    There is proposed an installation for measuring quantities of liquid (of the liquid measuring motor type) with two cylinders of which the pistons cooperate by means of cranks. Each piston has a crank-pin. To vary the crank radius of a crank-pin and thereby vary the stroke of a piston for the fine adjustement of the traversing fluid quantity, the excentricity of the pin is adjustable with respect to the crank-shaft in two parts. To this effect, the pin pivots on a turning portion of an excentric sleeve, said sleeve being closely connected by a worm screw to the crank-shaft. Both pins are arranged on a guiding disk with an angle of 60<o> with respect to their axes, they are supported by roller bearings and cooperate with the pistons which are connected to two mutually guided parallel spiders.

    专利说明:

    The invention relates to flow meters that can be used to measure fluid flow.
    The aim of the invention is to improve the measurement accuracy.
    FIG. 1 shows a device for measuring a descent, longitudinal section; in fig. 2 is the same cross section.
    The device contains pistons 1 and 2 located opposite to the axis of the crankshaft and interacting with two crankpins 3 and 4 in such a way that one of the two pistons reciprocates while the other piston passes a dead point. On the sides, the housing is closed with lids that restrict the separate working chambers 5. At the bottom dead spots, both pistons form a common working chamber 6.
    Both crank pins are mounted on a guide disk 7 located concentrically between the shaft sections 8 and 9 between the cross curtains. With respect to the axis of this guide disc 7, both crank pins 3 and 4 are eccentric and fixed to the guide disc at an angle of 60 (figure 2). The crank pin 3 converts the reciprocating movement of the piston 1 into the rotary movement of the shaft part 8, while the crank neck 4 converts the reciprocating of the piston .2 into the rotary motion of the shaft part 9.
    The relative movement of the pistons to each other is transmitted to the two Hbie crank of the crankshaft neck 3 and 4 through cross slides 10 and 11, conjugated to its piston and acting as a crank with a straight offset, one end of which is rigidly connected to the piston. Thus, the cross link 10, connected to the piston 1, interacts with the crank pin 3, and the cross link 11, connected to the piston 2, with the connecting rod neck 4.
    The cross-curtains of both pistons are parallel to each other at a certain distance and, for the straight linear direction of the ends of the curb, at the fixing point with the piston are provided with longitudinal cuts 12 and 13, in which the sliders 1.4 and 15 are made of plastic, are fastened

     using screws 16 and 17 on the neighboring cross-curtains.
    The bottom of the installation and the change in stroke of the piston 2 can vary the eccentricity of the crank neck 4. To this end, the crank neck is installed in the eccentric rotating together with the shaft part 9 the sleeve 18, which is held with geometric closure in the direction of rotation of the shaft part 9 by means of the movable screw 19. In the quiescent position, the worm is held to the spring 19 by a spring 20,
    The eccentric sleeve 18 and the worm to 19 are closed with the provision of hermetically j-o screw seal 21. After screwing the screw cap onto the support flange, which serves as a support for the eccentric bushing, as well as half of the cylinder body, screw): the cap can be sealed, for which a stopper 22 is provided, which is sealed.
    In order to transfer the crankshaft crankshaft crankshaft to the crankpins, the cross curtains 10 and 11 are provided with guide rails 23 and 24 in the form of longitudinal grooves that run transversely to the reciprocating movement of the piston and the axis of the crank pin and perceive the supporting rollers 25 and 26 covering the crankpins 3 , four,
    The upper part of the crankshaft 8 above the cylinder body is connected to a rotary damper 27, having distribution channels for supplying the measured liquid to separate working chambers and diverting it to the drain.
    about
    The device works as follows.
    The fluid j entering the housing, the flow rate of which is to be measured, displaces both pistons, which are driven by the crank mechanism to rotate the crankshaft. The stroke of the piston 1 is determined by the eccentricity of the crank pin 3 and is constant. By changing the eccentricity of the crankpin neck 4 with the aid of a screw 19 in the eccentric sleeve 18, the piston pitch 2 can be set and further adjusted. A crankshaft driven in rotation is connected to provide a drive with an indicator device (not shown) by which the value of the flow rate of the fluid can be calculated.
    3
    The device is applicable not only to measure fluid flow rates, but also to measure the flow of gaseous media.
