摘要： A hydraulic control unit includes a plurality of radial pump units driven by a common drive means. Each of the pump units is provided with an individual control assembly in the form of a control lever for rotating a cam which adjusts the eccentricity of a guide ring coupled to the radial pistons of a pump unit. In this way, the direction and magnitude of flow from the pump is controlled, being fed to or from the pump through a pair of conduits. The conduits are connected to a valve which, in response to the direction of flow in the conduits, is shifted to direct fluid flow in one of two directions through a hydraulic work unit. The valve also serves to direct fluid received from the work unit to a common condenser.

摘要： A hydrostatic radial piston engine with two rotors that are supported on an axle so that they can rotate easily thereon. The rotors have a plurality of radial bores with displacement elements (pistons with slide ring) therein, sliding on the inside of a piston ring. The bores are connected via control slits with transport channels (high-pressure/low-pressure) that open on a side on the rotors for the purpose of controlling the transport of the pressure medium. The two rotors can be rotated easily on the axle which mounted on an intermediate bottom. The intermediate bottom is disposed between the rotors. Check plates are disposed on the ends of the axle which take up the axial forces produced by the pressure medium in the control slits of the rotors. The piston rings are supported in the intermediate bottom by a common connecting shaft.

摘要： The folded channel radial pump assembly (10) comprises a housing (12) having therein a stepped diameter bore (14) receiving a rotor (30). The rotor (30) is attached by way of a flexible coupling (50) with the output shaft (61) of an electric motor (60) attached to the housing (12). The rotor (30) includes one or more intake (26, 36) and exhaust (28, 38) ports, the ports (26, 28, 36, 38) being radially aligned and communicating with the stepped bore (14). The rotor (30) includes one or more pairs of radial openings (70, 72; 170, 172) disposed substantially parallel to one another and each pair connected by way of an axial passageway (74; 174), one radial opening (70, 170) of the pair being aligned axially with the respective set of intake (26, 36) and exhaust (28, 38) ports and the other radial opening (72, 172) having therein a resilient mechanism (77, 177) biasing a piston ( 76, 176) and follower mechanism (75, 175) outwardly into engagement with an eccentric diameter section (24, 124) of the stepped bore (14). Rotation of the rotor (30) by the motor (60) causes the follower mechanism (75, 175) and piston (76, 176) to reciprocate within the other radial opening (72, 172) and effect the movement of fluid between the intake (26, 36) and exhaust (28, 38) ports.

摘要： The invention relates to a radial piston type pump comprising a casing, a shaft, two or more piston carriers mounted on and driven by the shaft, and a curved track surrounding the piston carriers. The piston carriers are axially movable on the shaft and pressure chamber and scaling means are provided between adjacent carriers to bias them in opposite directions against the internal casing walls which form a chamber in which the carriers are rotatably mounted. Fluid inlet and outlet means in one of these casing walls has fluid communication with the inlet and outlet passages in the carriers and the biasing of a carrier against this wall serves to provide sealing between the relatively rotating surfaces to minimize the leaking of fluid between these surfaces.
