    Radial piston pump, particularly for liquids, comprising at least one radial cylinder, at least one radial piston with associated piston head, at least one piston guide shoe, at least one eccentric element, and a device for attachment of the radial piston with the piston guide shoe or shoes. The piston heads contact with their bearing surfaces the bearing surfaces of the associated piston guide shoe or shoes, but the piston heads are not attached with the piston guide shoes at their bearing surfaces. On the side not contacting the piston head the piston guide shoe contacts the eccentric element. The piston head has an outer shoulder, which is grasped by the device for attaching the radial piston with the piston guide shoe or shoes. This device comprises a connecting sleeve associated with each individual radial piston, which embraces with an inner flange the outer shoulder of the associated piston head. The connecting sleeve has an outer sealing shoulder adjacent the piston guide shoes, which grips the piston guide shoe or shoes. The connecting sleeve has on its end adjacent the radial piston a spring retaining ring, to which a spring holding ring on the associated radial cylinder is positioned opposite thereto and corresponds. Between the spring retaining ring and the spring holding ring a compressible spring is positioned, which surrounds the radial piston.

    (54) RADIAL PISTON PUMP (57) The invention improves the service life of the pump. Cylinders 2 are located in the housing 1 in a star-shaped manner. In cylinders 2 there are piston groups, each of which has a piston 3 with a support shoe made of two parts. The guide part 4 belongs to the piston 3. The support part 5 is installed with the possibility of contact with the eccentric 6. Both parts 4.5 are interconnected between

    fight with the formation of a spherical hinge on the contacting surfaces i7, 8. On the piston 3 there is a supporting Idisk 10. Parts 4, 5 of the shoe are connected by an I coupling in the form of a stake, an element 14, covering part 5 and attached to disk 10 with screws 15 installed for 1
    The invention relates to pump construction, in particular to radial piston pumps for hydraulic media.
    The aim of the invention is to increase the service life.
    Fig, 1 shows a piston group of a radial piston pump, a slit; in fig. 2 is a view A of FIG. one.
    The radial piston pump comprises a cylindrical housing 1 with star-shaped cylinders 2 with piston groups installed in them, each of which has a piston 3 with a support shoe made of a two-part component, a guide 4 belonging to the piston 3, and a support 5 installed with the possibility of contact with the eccentric 6, which are conjugated with each other with the formation of a spherical hinge on the contact 1 | ruler surfaces 7 and 8. The porpen 3 has an outer hinge flange 9 for mounting the support disk 10. The piston group is equipped with troystvom for forcibly urging the bearing portion of the shoe 5 to the eccentric 6, the drive shaft 11, 12 comprising a compression spring enclosing the cylinder 2 and radially disposed between the cylindrical body adjacent to the washer 1 13 and support disc 10 piston. The guide 4 and the support 5 of the shoe part are connected by a coupling sleeve in the form of an annular element 14, which encloses the basic part 5 of the shoe and is attached to the basic disk 10 by means of screws 15 installed radially relative to the annular element 14.
    When the radial piston pump is operating, the spring 12 acts on
    Ideally, relative to element 14. For pressing part 5 to eccentric 6, a spring 12 is installed, which, together with element 14, provides for forced driving of piston groups, not allowing depressurization and the appearance of shock loads. zp f - ly, 2 ill.
