摘要： The invention relates to a hydraulic planetary piston type machine and particularly to the rotary slide valve thereof. This type of machine has a rotary piston gear having rotational and orbital movement and a cardan type shaft connects the slide valve to the piston gear. The valve has inlet and outlet, annularly shaped, axially spaced distributor grooves in axially spaced relation. Alternately arranged inlet and outlet stub grooves extend axially from the distributor grooves into axially overlapping relation. The stub grooves in the valve have a commuting action with circumferentially arranged ports in the casing to provide for feeding and exhausting pressurized fluid to and from expanding and contracting chambers formed by the piston gear. In smaller machines the correspondingly smaller flow passages present sufficient flow resistance to substantially affect the efficiency of the machine. In the machine disclosed herein the stub grooves are provided with oblique or curved sections so that the resistance to fluid flow between the distributor grooves and the stub passages is reduced and the efficiency of the machine is thereby substantially increased.
摘要翻译：本发明涉及一种液压行星式活塞式机械，特别涉及一种其旋转滑阀。这种类型的机器具有旋转和轨道运动的旋转活塞齿轮，万向型轴将滑阀连接到活塞齿轮。阀具有沿轴向间隔开的入口和出口，环形的，轴向隔开的分配槽。交替布置的入口和出口短管槽从分配器槽轴向延伸到轴向重叠的关系。阀门中的短管槽具有在壳体中周向布置的端口的通勤作用，以提供加压流体进入和从由活塞齿轮形成的膨胀和收缩室的排出。在较小的机器中，相应较小的流动通道具有足够的流动阻力，从而基本上影响机器的效率。在本文公开的机器中，短管槽设置有倾斜或弯曲部分，使得在分配器槽和短截线通道之间的流体流动阻力减小，从而显着增加了机器的效率。

摘要： Disclosed herein is a rotary engine operable as an internal combustion engine or powered from an external source, the engine comprising essentially three parts: (1) an outer housing or body, (2) a valve shaft extending axially through the body and having an eccentric mounted thereon, and (3) a rotor journalled on the eccentric. The shape of the internal surface of the housing and the rotor is such as to define a plurality of variable volume working chambers between the rotor and the housing. The rotor and internal surface of the housing may be cylindrical with the variable volume working chambers formed by sealing means projecting from the rotor in contact with the internal surface of the housing. The rotor and internal surface of the housing may also have a multi-lobed configuration with there being one less projecting lobe on the rotor than lobes in the housing with the projecting lobes of the rotor being essentially the same size and shape as those of the housing.

摘要： An arrangement for minimizing the pressure differential across shaft seals is characterized by a pump powered by the rotative force of a shaft to pump a fluid from a reservoir chamber into a chamber next-adjacent to each shaft seal. When the pressures in the chambers adjacent to the seals exceed a predetermined magnitude, a pressure relief arrangement is opened, thus venting the chambers and maintaining the differentials across the seals as minimal as possible.

摘要： Axial flow paths are established between the ring gear of a rotatable fluid displacing device and the housing of an associated control valve by radial clearance passages formed in the ring gear and spacer in axial alignment with axial flow passages of the housing through which threaded fastener shanks extend to hold the ring gear, spacer and housing assembled. The gaps between the internal teeth of the ring gear are radially extended to receive the fasteners therethrough with a close assembly clearance along radially outer portions of the fastener shanks.

摘要： A progressing cavity, positive displacement rotary pump for liquid or semiliquid material, having a specially designed flexible coupling shaft for connecting a drive shaft to an orbital rotor. The pump components include a tubular stator with an interior helical surface and a hollow tubular orbital rotor within the stator operably connected to the shaft and having an exterior helical surface. The rotor and stator define therebetween sealed pumping cavities that advance axially as the rotor rotates and orbits within the stator. The rotor has a tapered socket with a polygonal transverse cross-section (e.g., pyramid-shaped) at its outer end. The rotor is coupled to the rotor drive shaft by the flexible coupling shaft that extends through the hollow rotor and that has an enlarged tapered head formed to fit tightly in the socket and be retained therein by a threaded fastener. The opposite end of the coupling shaft is connected to the drive shaft outside of the rotor. The coupling shaft flexes to accommodate orbital movement of the rotor during operation of the pump. Also, a unique seal retainer is used to locate a packing-gland-type shaft seal for the drive shaft. The retainer facilitates removal and replacement of the seal components.

摘要： A fluid operated device in which an externally toothed rotor is rotatably disposed in a chamber and an internally toothed member is orbitally but not rotatably disposed in the chamber about the rotor. The rotor and orbital member are operative upon relative rotation to form fluid containing pockets therebetween and suitable fluid ducts are provided for conveying fluid to and from the fluid containing pockets. The orbital member is provided with means to cooperatively engage the housing to limit, or prevent unidirectional rotational motion of the orbiting member but to allow orbital movement about the axis of rotation of the rotor.
