    摘要: A radial piston device (100) includes: a housing (102), a pintle (110), a rotor (130), a plurality of pistons (150) and a drive shaft (190). The radial piston device also includes a mechanism for minimizing deflection or curvature of the pintle shaft (112), which may be caused by a resulting pressure applied to the pintle shaft. In one example, the mechanism may be implemented by at least partially supporting the rotor by the housing with a bearing while the rotor is also supported by the pintle shaft with another bearing.

    摘要: A hydrostatic radial piston machine includes a radial cylinder block with cylinder bores which extend from an outer circumferential surface of the radial cylinder block into an interior of the radial cylinder block a number of pistons which corresponds to the number of cylinder bores; a cam ring and ends of the pistons which face away from the radial cylinder piston block are supported movably on an inner circumferential surface of the radial cylinder block during a rotation of the radial cylinder block; two control plate elements which extend respectively with a face oriented towards the radial cylinder block towards a central plane of the radial cylinder block, which central plane is perpendicular to the rotation axis. Each control plate element includes a bearing portion in which radially acting forces are transferable to a respective mating surface in the housing or housing cover mounted in the housing.

    摘要: A rotary pump is provided having a chamber arranged in a body and a displacement member disposed in the chamber for reciprocating therein. A drive member is used to move the displacement member within the chamber in response to relative rotation between the body and the drive member. A radial valve arrangement may be used to time when the chamber is in fluid communication with inlet and outlet ports on the pump.

    摘要: A rotary pump such as a rotary fuel injection pump comprises a pump body; a rotor rotatably supported by the pump body and responsive to mechanical pulses to pump a fluid; and a stator ring (208) supported by the pump body and having a ring of projections (209) arranged to deliver mechanical pulses to the rotor when the rotor rotates relative to the stator ring. The stator ring (208) has a vibrational mode which is induced by delivering the mechanical pulses to the rotor. The pump body supports the stator ring across an interface which is a complete annulus or a partial annulus. In order to reduce the transmission of vibration from the stator ring to the pump body, the interface and/or stator ring incorporate cavities at the antinodes of the vibrational mode of the stator ring.

    摘要: A radial hydrostatic motor (radial piston machine) has a cylinder spider rotationally fixed and secured against axial displacement on a shaft and having a plurality of radial bores with pistons and sliding blocks that slide on the inner face of a hub ring or bushing. The bores communicate through control slots with high/low pressure delivery channels that open laterally into the cylinder spider in order to control the hydraulic media flow rate. Two mutually spaced rotors have bores with intercommunicating opposite control slots. Between both rotors is provided a housing intermediate partition having control disks opposite to the rotors and provided with channels which correspond to the control slots.

    摘要: A hydrostatic displacement machine has in a revolving cylinder block several displacement elements movable in a guideway and having a radial position during the rotation of the cylinder block determined by a nonrotating displacement ring. The displacement elements, viewed axially, are retained on the displacement ring by two retaining rings. The retaining rings feature relative to the displacement ring a radial seal. The axial seal of the retaining rings is effected in standstill, relative to the housing or housing lid, by way of spring elements, and during the pumping operation, by a contact force which is indirectly dependent on the operating pressure.

    摘要: The ease of assembly of a radial plunger pump is improved while preventing an external leakage of liquid. A pump housing 2 in the form of a cylinder having a closed bottom contains a pintle 4 therein, which is secured to the bottom of the pump housing 2 by a bolt 6. A rotor 8 is rotatably fitted around the pintle. The rotor is formed with a plurality of radially extending cylinder bores 8a, in each of which a plunger 10 is slidably disposed. A guide ring 16 is disposed around the rotor. A motor 20 is fastened to and secured to the opening of the pump housing, and includes a drive shaft which is connected to the rotor to drive it for rotation. By allowing parts to be assembled into the pump housing in one direction, the ease of assembly is improved while preventing a liquid leakage.
