摘要： An hydraulic centrifugal piston motor having mulitple piston circumferentially disposed at right angle to shaft axis, having a rotational power moment that occurs twice each revolution for each cylinder. The power stroke for each cylinder would occur for a duration of 90 degrees twice during each 360 degree operating cycle. Hydraulic input is applied to opposing pairs of cylinders and overlap of successive power strokes provide rotational balance and cancels net reaction forces applied to the bearings. Another feature of the motor would be the particular design of the power transfer device. The thrust of the power transfer device is applied axially to the drive shaft providing a smooth transfer between the hydraulic input power and the mechanical output power.

摘要： A flow divider assembly for use with a hydraulic pump provides flow to separate drive motors for use in a vehicle or other application. A pair of flow divider motors may be mounted on a block and have a common axis of rotation. The ratio between the two may be controlled by adjustment of the angles of the respective thrust bearings of the flow divider motors. A valve may connect the outlet of one of the flow divider motors or the outlet of the other flow divider motor. passage to the second outlet passage. Additional bypass valves may be provided to permit direct connection between the hydraulic pump and the separate drive motors.

摘要： A hydraulic rotating axial piston engine having a housing, enclosing a cylinder barrel journaled in the housing for rotation around a barrel axis. The housing also has a number of circumferentially arranged cylinders with a number of pistons reciprocating between two defined end positions. The pistons cooperate with an angled plate in order to obtain the reciprocating movement. The axial piston engine has an input/output shaft, and the cylinder barrel has channels connecting each cylinder to port(s) in the cylinder barrel. The ports alternatively act as inlet and outlet ports. The housing has an inlet and outlet channel, each having a kidney-shaped port, facing towards the inlet and outlet ports of the cylinder barrel. The kidney-shaped ports communicate with a number of the ports at the barrel. The cylinder barrel ports extend in both directions outside the cylinders in the two circumferential directions of the cylinder barrel. The channels open to the cylinders along the peripheral wall of each cylinder, and the opening to the cylinders has substantially the same area as the area of the ports of the barrel.

摘要： A hydraulic device (1) comprises a housing (2) and a shaft (3) which is rotatable about a first axis of rotation (4). The shaft (3) has a flange (8), a partly spherical portion (16) and a plurality of pistons (9), which are fixed to the flange (8). The device (1) also has a plurality of cylindrical sleeves (11), wherein each sleeve (11) has a sleeve bottom (13) comprising a sleeve opening (14) including a centreline (23). The sleeves (11) cooperate with the pistons (9) to form respective compression chambers (12) of variable volume. A barrel plate (15) is mounted on the partly spherical portion (16) and has barrel plate ports (21) including respective centrelines (22). The sleeves (11) are rotatable about a second axis of rotation (19) which intersects the first axis of rotation (4) by an acute swash angle. The barrel plate (15) is coupled to the shaft (3) in rotational direction thereof by means of a plurality of pin-groove couplings creating a plurality of pivot axes (24) about the second axis of rotation (19). The widths of the grooves (18) allow the pins (17) to move within the respective corresponding grooves (18) in rotational direction about the second axis of rotation (19) under operating conditions. The relative position of the shaft (3) and the barrel plate (15) in rotational direction about the second axis of rotation (19) is adapted such that under operating conditions each centreline (22) of the respective barrel plate ports (21) fluctuates in rotational direction about the second axis of rotation (19) with respect to the centreline (23) of the corresponding sleeve opening (14) within a range in which the centreline (23) of the sleeve opening (14) lies.

摘要： In a bent axis type axial piston motor, so as to smoothly rotate a drive shaft without lowering motor efficiency and brake the drive shaft if necessary, when the drive shaft is rotated through a cylinder block by causing piston rods to reciprocate, relative rotation between separate plates and friction plates is allowed by removing a pressing force applied by a braking piston, and when the separate plates and the friction plates are pushed to a brake force receiving plate by the braking piston, relative rotation between the separate plates and the friction plates is restrained and thus the drive shaft is braked. Restriction members are disposed between a casing and the brake force receiving plate so as to restrain the brake force receiving plate from moving relative to the casing along the axis of the drive shaft.

摘要： In a bent axis hydraulic machine, a back plate and cylinder barrel vary in distance from a drive plate as a stroke angle of the cylinder barrel changes, thereby minimizing unswept fluid volume in the cylinders of the barrel at any stroke angle. Distance is controlled by one or more rollers, engaging respective tracks that define a profile of contact that determines the distance as a function of the stroke angle. Telescoping fluid supply channels are employed to maintain a fluid supply to the cylinder barrel as the distance changes.

摘要： Mounting structure for housing-free hydraulic axial piston machines of the bent axis or swash plate design, having a closing plate on which a cylinder block unit with displacing pistons arranged therein is supported, and having a drive or driven shaft. The mounting structure here is designed in the manner of a basket and has a receptacle for the drive or driven shaft and at least two struts which are in each case connected at one end to the receptacle and at the other end to the closing plate in such a manner that the closing plate, the cylinder block unit and the drive or driven shaft are held—analogously as in a housing—in a functionally ready position.
