Abstract: The invention relates to the distributor valve aspects of an internally shafted orbital piston machine. The distributor valve includes a fixed and movable valve part with the movable valve part being biased against the fixed valve part by an axially movable plunger. A central bearing bushing between the fixed and movable valve parts provides for precise centering of the movable valve. The fixed valve part is formed by brazing together two annular elements.

Abstract: The invention relates to a pump assembly which may be utilized as a fuel oil pump and which has constructional features which minimize the possibility of air binding. The assembly has a rotating casing member in which pumping elements are housed and which is surrounded by a casing so as to form a suction chamber which surrounds the rotating casing member. The rotation of the casing member causes liquid in the suction chamber to also rotate and form a ring of liquid. The rotating casing member has an eccentrically positioned inlet which passes through the ring of liquid so formed once during each cycle of rotation and this insures the introduction of liquid, as distinguished from only air, into the inlet.

Abstract: The invention relates to an oil pump assembly comprising a casing in which pumping elements are disposed and in which fluid intake and exhaust passages are formed. A bypass passage with valve means therein is between the intake and exhaust passages. An electromagnet is mounted in the casing and the armature thereof is associated with and operates the valve means. The electromagnet is controlled jointly with the motor which drives the pump assembly in a manner such that the valve means are closed when pump assembly is operating and open when the pump assembly is turned off. The opening of the valve means in this manner permits pressurized fluid to be bypassed to the intake passage such that the usual pressure regulating and cut-off valve connected to the exhaust or pressure outlet side will close instantaneously upon the motor being turned off by reason of the instantaneous reduction of pressure caused by the instantaneous bypassing of the pressuized fluid.

Abstract: The invention relates to a pressure regulating valve assembly for pumps. The assembly includes two relatively movable pistons with one being a setting piston acted upon by supply pressure and a rated spring and the other being a regulating piston which controls a return orifice and is acted upon by the supply pressure and a differential spring. The supply pressure for the regulating piston is delivered through a modulated restrictor passage with the pressure drop in the restrictor passage corresponding to the quantity of pressurized fluid delivered therethrough. The regulating piston is hydraulically loaded by only a differential pressure which provides a greater ease in movement and allows a relatively weak differential spring to be utilized.

Abstract: The invention relates to a rotary piston type machine of the type which utilizes a gerotor mechanism for the expansible chambers. In the prior art the ring member of the gerotor normally or often has seven internally extending teeth and holes are normally provided in the seven teeth to accommodate seven screw bolts used for clamping together the casing parts. In the machine hereof the gerotor ring member is clamped between two side disks which in turn are disposed in counterbores of concentric casing collar portions which collar portions are in axially spaced relation to each other when in their clamped positions. Only four screw bolts are utilized for clamping together the casing parts and these bolts are positioned radially externally of the gerotor ring member and the two side disks thereof.

Abstract: The invention relates to fluid pressure motors and pumps of the type having a gerotor displacement mechanism. The rotary type valving for gerotor mechanisms has first and second sets of alternately arranged ports which have sequential fluid communication with ports of stationary passage which are connected to the displacement chambers. Optimum efficiency normally requires that these ports be formed and positioned with great precision. Auxiliary passages associated with the teeth of the gerotor mechanism itself, and which connect adjacent displacement chambers, effects a precise internal distribution of fluid so that only a gross of coarse fluid distribution is required of the valve ports and the fine or delicate distribution needed for optimum efficiency is performed by the auxiliary passages.
