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 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.
