    The invention relates to pump construction. The aim of the invention is to reduce the size of the pump, which is achieved by introducing a system of forced circulation lubrication into the pump with means for cooling the lubricating fluid. The pump includes a housing and a pair of piston-cylinder, forming a working chamber. The drive element - the slider is mounted on the eccentric of the drive shaft. The pump has a forced circulation lubrication system that includes a storage tank, an injection lubrication pump, a recirculation collector, a recirculation pump, an overflow channel with a control unit for regulating the filling of the recirculation collector. A heat exchanger in the form of a system of heat exchange tubes through which the pumped medium passes through the pump is introduced into the accumulator tank, which removes heat from the lubricating fluid in the accumulator tank. The lubricant is supplied to the piston, reducing the frictional force and heat removal resulting from the operation of the pump. 11 3.p. f-ly, 6 ill. "OU)

    The piston machine, in particular, the nopuiHenofi pump, comprises a housing 1, at least one pair of pistons 2 or 1 lr to form a working chamber 4 of variable volume, at the pump it is filled with working chambers that are 1 star older than 1 star.
    The piston 2 is provided with an elastic, deformable 1-lang-like sealing element 5 for sealing the working chamber 4. The piston 2, when the rotary driving element slider 6 is installed, mounted on the eccentric of the drive shaft 7, is brought into reciprocating motion , while the cylinder 3 at the end facing the driving element slider 6 is encompassed by a driving link in the form of the glass 8, the bottom of which is arranged to be in contact on the plane with the driving element slider 6, its outer walls are in contact with the housing 1, t The cup wall 8 in combination with cylinder 3 and body 1 form additionally a variable volume chamber 9, and its internal walls together with the end of cylinder 3 form an auxiliary chamber 10, with an additional 9 and auxiliary 10 chambers communicating with each other by means of a throttle channel 11, which can being formed by an annular gap between the inner surface of the walls of the glass B and the outer surface of the cylinder 3, the Additional chamber 9 is connected with the storage tank 13 made in ide annular chamber in the housing 1, concentrically situated axis of rotation of the drive shaft 7. The storage container 13 is filled with lubricating fluid. Piston 2 using prhtkiny
    14 is pushed to the bottom of the glass, and each working chamber 4 is provided with a suction
    15 and 16 discharge valves for alternating communication with the suction 17 and discharge 18 manifolds.
    The piston machine is equipped with a lubrication device, made in the form of a system with forced circulation including an accumulation tank 13, a lubrication pressure pump 19, a recirculation collector 20, a recirculation pump 21 and an overflow channel 22 with a governing body 23 having a float 24 placed in recirculation collector 20. The stencil organ 23 serves to regulate the filling of the recirculation collector 20. The lubricant from storage tank 13 through channel 25 enters the pump suction line 19 cm. from where channel 26 is fed through filter 27 to ring-shaped manifold 28, from which pressure lubricant through pressure channels 29 and 30 with integrated throttles 31 and 32, respectively, goes to separate cylinders 3. Pressure channel lubricant 29 is supplied for lubrication the contact zone of the sealing element 5 with the cylinder 3 and is diverted from this zone into the auxiliary chamber 10, from where it passes through the throttle channel 11 to the additional chamber 9. Since the additional chamber 9 is through an equalized channel 12 having more The cross section communicates with the storage tank 13, the pressure in the additional chamber 9 is always lower than the pressure in the auxiliary chamber 10, which ensures that the lubricating fluid is directed away from the contact zone of the sealing element 5 with the wall of the cylinder 3. Through the channel 30, the lubricating fluid is supplied under pressure the lubrication zone of the grinding cup 8 with the housing 1, from where through the channels 33 it enters the contact zone of the bottom of the glass 8 with the slider 6 and is withdrawn from this zone into the recirculation collector 20. The recirculation pump 21 draws liquid from irkul insulating collector 20 and the channel 34 returns it to the storage tank 13.
    In order to prevent foaming in the system of forced circulation lubrication, the rotor 35 of the recirculation pump 21 has several knurled slots 36, which are similar to the blades of a radial centrifugal pump. When the rotor 35 rotates, which is in retaining slots 36, the lubricating fluid, due to significant centrifugal forces, undergoes separation into lubricant with a greater or lesser content of the liquid phase or, conversely, with a lower or higher content. eat gas or foam.
    In the area of the vent 37, having an angular extent of less than 180, from the retaining slots 36 of the rotor 35 in the radial direction, with a corresponding deceleration, only that part of the lubricant that contains very little gas or foam is ejected. After the passage of the window 37, the retaining slots communicate with a diversion window 38 into which that part of the lubricant which contains a large amount of gas or foam falls, and this part of the lubricant through the channel 39 (FIG. 3) returns to the recirculation collector 20 through the channel 34. Windows 37 and 38 are located jumpers 40 and 41, during passage of which the ends of the slatted slots 36 are closed, and jumper 41, which has a significantly greater angular extent, serves to separate the phases of the lubricating fluid with different densities. The lubricant from the recirculation collector 20 is fed to the recirculation pump 21 via a channel 42.
    In addition, for separating gas and foam, a recirculation pump 21 is provided with a slit cavity 43 located in a radial direction around the rotor 35, in which, as the latter is rotated, a radial, circulating trajectory stream is created (Fig. 4), which facilitates the collection of lubricant liquids with low gas content in the outer radius of the area, retaining slots 36 and, if necessary, cause a partial return of the foam collected in the radially inner region of the retaining slot 36 in the direction of the pump suction chamber.
    The piston pump is also equipped with a pump 44 for pumping the pumped medium, which is, for example, a pump. Q 5

    1Gp, axial vane pump, the rotor of which is placed in the bore 45 of the housing 1, and mounted on the end 4G of the drive shaft 7 (not shown in Figures 1 and 5 of the pump roir).
    The pumped medium is supplied to the pump 44 in its suction cavity 47 through the opening 48 in the cover 49, and discharged from the cavity 50 through radial channels 51 into the annular suction manifold 17, from which the pumped medium along the axial channels 52 (figure 5 shows only one such channel), the number of which is equal to the number of pa6o4trx cylinders. enters the suction valve 15 of the corresponding working chamber 4.
    Thus, the pumped medium at the inlet of the piston machine is under excessive pressure, which ensures reliable filling of the working chamber 4 at the suction stroke. The piston machine is equipped with a device for cooling the lubricating fluid, including a heat exchanger through which the pumped medium flows, the flow of which is created by the pump 44. The heat exchanger is located in the storage tank 13 for the lubricating fluid and includes a system of channels through which the pumped medium flows. The channel system of the heat exchanger includes a channel 53, made coaxially to the channels 52 and communicated with the suction manifold 17. Each of the channels 53 enters a ring-shaped collector channel 54 formed in a roof 49. A connecting node 54 is connected to the channel 54 via a radial channel 55 with an adjustable throttle 56 distribute 57, located in the accumulation tank 13, Diametrically opposite to the distributor 57 in the accumulation tank 13 is located another connecting node-collector 58, which by means of a radial channel 59 communicates with the suction cavity 47 of the pump 44 of the swap. The distributor 57 and the collector 58 are fixed in the end wall of the housing 1 and are interconnected by a system of heat exchange tubes 60 arranged ring-shaped in the accumulation tank 13.
    Piston machine, in particular the pump works as follows.
    In case of shrouting G7ripol 1st dad 7, the piston 2 with glass 8 is rotated by means of a rotary driving element 6 in a reciprocating motion, which leads to a periodic increase and decrease in the volume of the working chamber A. At the same time, the MefiHo with the drive shaft 7 is driven
