摘要： The invention relates to a hydraulic motor, which comprises a surrounding frame casing; an internal cylinder block with radially arranged cylinders and a stationary axle of the hydraulic motor attached thereto; pistons reciprocating in the cylinders and bearing the inner surface of the frame casing, which surface is formed as a running surface guiding the movement of the pistons; a fluid distributor mounted around the axle to rotate together with the frame casing, for the distribution of the hydraulic fluid into cylinder chambers and away therefrom via openings provided in the cylinder block; and feed and exhaust channels for the hydraulic fluid. The object of the invention is to improve such a hydraulic motor by compensating, without complicated balancing elements, the force caused by the pressurized hydraulic fluid and separating the fluid distributor and the cylinder block. This has been solved according to the invention in such a manner that a ring space is formed between the fluid distributor and the axle, by means of stepped counter surfaces of the axle and the fluid distributor, said ring space being formed in the feed channel for the hydraulic fluid.

摘要： A radial piston device such as a radial piston motor (10) has a rotor assembly (34) rotatably positioned within a cylindrical race (43) which is movable to a first displacement position by a first piston (52) and a second displacement position by a second piston (53). A pintle (26) extends into a bore (36) of a rotor (33) of the rotor assembly (34) and has first and second ports (27,28) for delivering fluid to and from the rotor (33). In order to reduce the size of the radial piston device and to minimize the number of external lines, a control valve (66) is positioned within a bore (59) of the pintle (26) and selectively controls fluid flow from one of the first and second ports (27,28) to the first and second pistons (52,53) for shifting the cylindrical race (43) between the first and second positions.

摘要： A hydraulic-powered motor for stepwise operation has a plurality of radial pistons in a rotatable cylinder block, the pistons engaging a cam track having a number of indentations which is different from the number of the pistons. Electrically operated valves are provided and are energizable in sequence to apply pressure pulses to the pistons to cause stepwise rotation of the cylinder block. Detent means may be provided to prevent rotation of the cylinder block in the absence of a pressure pulse to any one of the pistons.

摘要： A radial type hydraulic pump motor according to the present invention has pistons, each of which is formed at its head portion with a concave or convex spherical surface. Engaged spherically with said spherical surface head portion is a piston shoe whose outer planar portion is slidably engaged with the inner planar portion of a crescent-shaped segment arcuately engaged with the inner peripheral surface of a drum case. Said piston shoe is formed at its outer planar portion with a hydraulic recess equal to the effective pressure receiving area of piston in area. Said recess is maintained in communication with a cylinder chamber. Accordingly, said spherically engaging portion and arcuately engaging portion make little sliding movements and only the outer planar portion of piston shoe and the inner planar portion of segment mutually make sliding movement under little contact pressure, thereby causing little wear to said engaging portion and sliding portion.

摘要： A variable displacement fluid transducer including a plurality of radial pistons arranged in pairs on a rotating piston barrel. Cam tracks circumscribe the pistons and convert the reciprocation of said pistons into rotary motion of a shaft means, or viceversa. Piston chambers provided in the barrel couple the pairs of pistons, and the cam tracks are adjustable to vary the displacement of the transducer by changing the relative reciprocating movement of the pistons comprising each pair.

摘要： The rotary cylinder block of a radial piston machine surrounds a control member whose outer surface has high pressure ports and low pressure ports communicating with the cylinders during rotation. The outer cylindrical surface of the control member also has a pair of circumferentially aligned first and second high pressure balancing grooves on either side of the high pressure ports and a pair of circumferentially aligned first and second low pressure balancing grooves on either side of the low pressure ports. The control member is formed with preferably straight diametrical ducts connecting the first and second high pressure balancing grooves with the first and second low pressure balancing grooves located on the same side of the high pressure and low pressure ports, respectively. The high pressure balancing grooves and the low pressure balancing grooves are filled, respectively, with high pressure fluid and low pressure fluid from the high pressure and low pressure ports, respectively, through the gap between the inner surface of the cylinder block and the outer surface of the control member so that the pressure fluid in the balancing grooves substantially centers the cylinder block on the control member.

摘要： The inward pressure exerted by the cylinder rotor of a hydraulic radial piston machine on the stationary control member on which the rotor rotates, is compensated by balancing chambers on control portions between the high and low pressure ports of the control member. Fluid under high pressure is supplied from the high pressure port to the respective control portion on which the inward pressure of the cylinder of the piston in the inner radial dead center position acts. The conduit system of the control member includes check valves preventing communication between the high pressure port and the low pressure port.
