摘要： A neutral by-pass for hydraulic fluid in a hydrostatic transmission is provided by an essentially closed conduit comprising a pair of bores and a channel communicating the pair of bores, all formed in the cam ring of the transmission. When the neutral point is attained, the bores will be communicated with oil dampening pistons in communication with the hydraulic fluid supply passages and the fluid pressure between the passages will be equalized. This will operate from either the forward or reverse direction. As the cam ring is angularly moved, essentially closed conduit is moved away from the dampening pistons, so there can be no fluid flow therethrough. When this occurs, all fluid flow goes to the motor rotor, causing output rotation.
摘要翻译：静液压传动装置中的液压流体的中立旁路由一个基本封闭的导管提供，该导管包括一对孔和连通一对孔的通道，全部形成在变速器的凸轮环中。当达到中性点时，孔将与与液压流体供应通道连通的止油活塞连通，并且通道之间的流体压力将相等。这将从正向或反向工作。当凸轮环成角度地移动时，基本封闭的导管从阻尼活塞移开，因此不会有流体流过其中。当这种情况发生时，所有流体流向电动机转子，导致输出旋转。

摘要： A piston machine, particularly a radial piston machine which includes a pintle supporting a rotor which has a plurality of radially extending bores in which radial pistons are guided. These bores are in communication with control chambers formed in the pintle. One of the chambers is a high-pressure chamber and the other is a low-pressure chamber. Pre-control grooves and additional passages are provided at the control chambers to prevent, during the operation of the radial piston machine the occurrence of pressure shocks at the inner and outer dead centers.

摘要： A variable displacement fluid pump comprises a rotor rotatably disposed within a housing, an eccentric ring movable close to and apart from the rotor to change a first eccentricity between a center of an inner periphery of the eccentric ring and a fixed center of rotation of the rotor so as to vary a displacement of the pump, and a plurality of pumping chambers each having a variable volume which changes sequentially to introduce thereinto fluid from an inlet port and to discharge therefrom fluid to a discharge port as the motor rotates. The rotor is so disposed that the fixed center of rotation of the rotor is spaced apart by a predetermined second eccentricity from a locus of the center of the inner periphery of the eccentric ring towards the discharge port.

摘要： In order to stabilize the line pressure developed by a line pressure regulator valve and simultaneously control the operation of a variable capacity pump in a manner that the latter exhibits the desired degree of response to changes in the line pressure, a flow restriction is defined in the bore of the valve itself. This flow restriction is defined between the wall of the bore in which the spool is disposed and a portion of the spool which extends between two adjacent lands and which has a diameter which is slightly smaller than that of the bore.

摘要： A vibration reducing shoe for biasing a cam ring of a variable displacement ball pump into engagement with a surface of the pump housing. In a hydrostatic transmission having a variable displacement pump and a fixed displacement motor a pair of shoes are located within bores in the pintle. The shoes are slidably received in the bores and exert a force against the cam ring which is proportional to the pressure of the fluid used to rotate the motor. Since the pump is reversible, one shoe is in fluid communication with one of the passages directing fluid to the motor and the other shoe is in fluid communication with the other passage. Accordingly, the force exerted on the cam ring by the shoes increases and decreases with increases and decreases in the pressure of the fluid from the pump to the motor.

摘要： The pump has a regulating element whose position is controlled by means of a first and second piston. The first piston is kept under pressure by the output pressure of the pump. The output side of the pump is also connected to a throttle valve which has a cross-section allowing fluid flow which varies as a function of pressure. The pressure difference created at the throttle valve output relative to the throttle valve input acts on a three-position three-port control valve which control the pressure on the second piston accordingly. The second piston has a larger diameter than the first piston.
