摘要： A rotor for a rotary screw machine has helical lobes (12) and grooves (14). A shell structure (18) forming the external surface of the rotor is made of pressed metal power. The rotor is manufactured by cold isostatic pressing of a powder in a vessel having a surface shaping rotor. The pressure is applied radially by means of a cast bag in which high pressure liquids acts. After the pressing process, the rotor blank is sintered and attached to a shaft (16).

摘要： An internally meshing gear-pump, or motor comprises inlet and outlet ports 27,28 for the working fluid through a sealing plate 5 mounted on the shaft 1, an externally-toothed gear 2 is longitudinally displaceable relative to internally-toothed gears 3,4 to vary the pump or motor displacement, a sealing member 6 is secured to the end-face of the gear 2 which separates the displacement chambers 29,30 from the varying volume spaces which may be filled by controlled working fluid formed in both longitudinal and diametrically opposite regions 11,12. When the gear 2 is moved longitudinally from the maximum displacement position to the extreme left to a reduced capacity position and thus varies the output of the pump or motor mounting these machines back-to-back or in other combinations, a continuously variable and or differential transmission of working fluid may be obtained. Additionally electrical windings 85,86 may be mounted in the casings 7,8.

摘要： An outer envelope trochoidal device is provided. The device includes a rotor shaft and rotor assembly, the rotor assembly having a peripheral surface that defines a trochoidal curve and includes a first and a second rotor half. Each rotor half has a trochoidal profile surface and an inner circular surface. The rotor shaft includes secured thereto a cylindrical sleeve that includes a radial flange to which at least one of the rotor halves is secured. The rotor halves are secured to each other by counterbolt means extending laterally through the rotor halves. One rotor half can include a tapped hole in the outer peripheral surface of the rotor and a channel extending from the end of the tapped hole to the sleeve on the rotor shaft. A chamber is defined by a portion of the sleeve and a portion of the rotor half pinned to the sleeve, the chamber being in fluid communication with the channel. When a fluid under pressure is injected into the channel and thereby the volume through the tap hole, the rotor halves are caused to separate and disengage the rotor shaft.

摘要： A rotary fluid pressure device (11) is disclosed of the type having a fluid displacement means (17), an inlet port (57), an outlet port (61) and a valve means (55) which cooperates with a housing (21;101;201) to define a main flow path communicating from the inlet to the volume chambers of the mechanism (17) and then to the outlet. The device includes an arrangement such as an orifice (89) or shuttle valve (111) having its inlet in communication with the main flow path downstream of the contracting volume chambers (29). The motor includes a lubricant flow path (81,83; 107,109; 207) which provides lubricant to the bearings and shaft splines. The orifice (89) or shuttle valve (111) provides a generally constant flow of lubricant despite variations in the motor load or motor speed.

摘要： A rotary hydraulic vane pump is disclosed of the type including a cam ring (19) defining an internal cam surface (21). The pump also includes a rotor (25) which defines a plurality of slots (27) which receive roller vanes (29). The internal cam surface includes a discharge arc surface portion (65) which is the cam fall portion of the cam surface. In one aspect of the invention, it is recognized that flow turbulence, pressure pulses and noise is caused by a slight net increase in the volume of a contracting fluid chamber (57) during cam fall, and that this increase is caused by radially inward movement of the roller vane during cam fall. In another aspect of the invention, the discharge port (59) is located such that fluid communication between the contracting fluid chamber and the discharge port does not occur until after the net increase in the volume of the contracting fluid chamber has ceased, and a net decrease in the volume of the chamber has begun.

摘要： The invention relates to a fluid pressure operated motor or pump of the type having a gerotor displacement mechanism which normally includes inner and outer wheel and ring gears which in operation have relative rotational and orbital movement therebetween. Such devices inherently have a form of valving wherein, with a commutating type of action, fluid is directed from the casing inlet to expanding chambers of the gerotor and directed from collapsing gerotor chambers to the casing outlet. Two embodiments are presented in which the first has the casing thereof fixed in space. In both units the commutator valving includes valving patterns in two valve plates attached to opposite sides of the casing and in the wheel gear which has orbital movement relative to the casing. The commutating valving arrangement has control ports on opposite sides of the unit for feeding and exhausting motive fluid to and from the unit and auxiliary ports on opposite sides of the unit to balance or equalize the pressure forces on each side thereof. Bolts are used for fastening the tightening together the casing side plates. These bolts are also used as guides for the orbital path of the ring gear and holes are provided in the ring gear to accommodate the bolts.

摘要： A rotary fluid pressure device (11) is disclosed of the type including an internal gear set (17) wherein the toothed members (23,27) define expanding and contracting volume chambers (29). The device further includes relatively movable valve elements (19,55) having engaging valve surfaces (71,73). One of the valve elements defines fluid passages (67) communicating with the volume chambers and the other valve element defines a plurality of valve passages (63,65). There is provided a secondary valving including a fluid passage (7) defined by the first valve element and a fluid passage (77) defined by the second valve element, the secondary fluid passages being in fluid communication when the respective volume chamber is approaching its minimum volume position to prevent trapping of fluid, and as it is leaving its minimum volume position, to prevent cavitation.
