摘要： An integrated hydrostatic transmission has a housing comprised of two separable elements detachably joined together along a substantially horizontal parting plane. A hydrostatic transmission including a hydrostatic pump, a hydrostatic motor, and a center section is separately mounted within the housing. The center section comprises a generally L-shaped member having a hydrostatic pump and motor mounting surfaces thereon disposed at right angles to each other. A pair of fluid ports is on each of the mounting surfaces, and internal passageways are in the L-shaped member connecting each of the fluid ports on one of the mounting surfaces with one of said fluid ports being on the other of the mounting surfaces. The L-shaped member comprises first and second legs integrally joined and extending at right angles to each other, with the first leg normally extending in a horizontal direction, and the second leg normally extending in a vertical direction. The first leg has upper and lower surfaces with the pump mounting surface being located on the upper surface. The pump is mounted on the pump mounting surface and has an axis of rotation. The second leg has a first surface extending upwardly from the upper surface of the first leg, and a second surface opposite and parallel to the first surface of the second leg with the motor mounting surface being on the second surface of the second leg. The motor has an axis of rotation perpendicular to the axis of rotation of the pump being mounted on the second surface of the second leg. The pump has an input power shaft extending through the housing.

摘要： A hydraulic axial piston motor or pump (8) of the type in which a rotor (10) has an odd-numbered plurality of cylinder ports (30) with which the arcuate ports (40,42) of a port plate (36) successively register. The port plate (36) is provided with fluid exchange ports (44,46) through which cylinders (16) communicate with a hydraulic capacitance system (81,82,84,86,93). The capacitance system (81,82,84,86,93) urges fluid into each cylinder (16) of the rotor (10) through an exchange port (44) after the associated cylinder port (30) has departed from registration with one arcuate port (40) but before the associated piston (14) has reached its bottom-dead-center position (72), and receives fluid from each cylinder through an exchange port (46) after the associated piston has begun its compression stroke but before the cylinder port has begun to register with a second arcuate port (42). Urging fluid into each cylinder eliminates cavitation effects that would otherwise result from having too large a decompression zone (68- 67), while receiving fluid from each cylinder prevents excessive pressurization that would otherwise result from having too large a precompression zone (67). The invention thus enables the use of arcuate ports (40,42) which subtend the more limited angular ranges required to provide a pump or motor that operates with a constant number of high-pressure cylinders and, consequently, with a constant clamping force between the rotor (10) and the port plate (36).
摘要翻译：一种液压轴向活塞马达或泵（8），其中转子（10）具有奇数个多个气缸端口（30），端口板（36）的弓形端口（40,42）依次与其连接寄存器。端口板（36）设置有流体交换端口（44,46），气缸（16）通过该流体交换端口与液压电容系统（81,82,84,86,93）连通。电容系统（81,82,84,86,93）在相关联的气缸端口（30）已经脱离与一个弧形对准的位置之后通过交换口（44）将流体推动到转子（10）的每个气缸（16）端口（40），但在相关联的活塞（14）已经到达其下死点位置（72）之前，并且在相关联的活塞已经开始其压缩冲程之后但在之前气缸端口已经开始向第二弧形端口（42）注册。将流体推入每个气缸消除了由于具有太大的减压区（68-67）而导致的空化效应，同时从每个气缸接收流体可以防止由于具有太大的预压缩区域而导致的过大的加压（67）。因此，本发明使得能够使用弧形端口（40,42），其对准提供用恒定数量的高压气缸操作的泵或电动机所需的更有限的角度范围，并且因此在两者之间具有恒定的夹紧力转子（10）和端口板（36）。

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： There is disclosed a hydrostatic motor provided with radially arranged hydraulic cylinders provided with radial pistons composed of pairs of pistons with different diameters fitted one into the other. The motor is selectively operable in either of two operating conditions, in a first of which the large and small pistons move as a unit in a heavy duty operation, and in a second of which only the small pistons move in a low duty operation. The motor includes a rotor and a stator, duct means arranged in the stator for the supply of pressure fluid to the pistons, a change-over unit within the motor, and a fluid distributor unit housed in the stator. The motor of the invention employs virtually the same distributing circuits during its operation in both its heavy duty and its low duty modes of operation.

摘要： An axial piston machine of the swashplate type has a movable valve plate at the piston end of the cylinder block, and displacement of the valve plate by a stroke control mechanism changes the tilt of the block. The valve plate has a front face subjected to the hydraulic end thrust of the cylinder block and a back face shaped conformably to and engaged with a cylindrical slideway in the machine body. The valve plate is guided against displacement in the direction of the axis of tilt by side surfaces of the machine body. At least one of the front and back faces is spherically arched to cause the hydraulic end thrust to urge the valve plate in a direction to keep one of its sides in continuous contact with a cooperating side face in the machine body. This prevents jamming and wedging of the valve plate in the slideway when the tilt of the cylinder block is adjusted, regardless of the existing load.

摘要： A pressure-responsive control body for use in a fluid handling device such as a hydraulic or pneumatic pump, compressor, motor, transmission or the like is movable axially in a housing and has a stationary control face adjacent to a control face of a fluid handling rotor. A fluid flow control area is formed between the control faces and two fluid containing pressure chambers are formed in the housing by two shoulders of the control body. The middles of the pressure chambers are eccentric relative to the rotor. The cross-sectional areas of the pressure chambers are a little larger than the cross-sectional area of the high-pressure equivalent zone of the fluid flow control area and the pressure centers of the high-pressure zones of the fluid flow control area and of the respective pressure chambers are located on an axis which is parallel to the axis of the rotor and one chamber extends in part radially beyond the control face of the control body. The housing is provided with a separable closing member for one of the pressure chambers.
