Abstract: The invention relates to a gerotor type rotary piston machine. The casing has a main axis and the gerotor gear set includes an externally toothed star member which is rotatable about its own axis and orbital about the casing main axis. A main drive shaft is rotatable about the casing axis and a universal type wobble shaft connects the main shaft to the gerotor star member. An annularly shaped valve is mounted in said casing for rotation about the casing main axis. The valve is in surrounding relation to the wobble shaft and is driven by the wobble shaft. An annularly shaped pressure plate which is nonrotatable but is capable of a small amount of axial movement is positioned behind the valve. The pressure plate is biased against the valve by pressurized fluid from the inlet port to provide sealing for both sides of the valve. Sealing rings are provided at the rear of the pressure plate betwen it and the casing to prevent leakage from the high pressure inlet regions to the low pressure outlet regions.

Abstract: The invention relates to a one-way valve and to a method for manufacturing a one-way valve. The method involves drawing a cupshaped housing from sheet metal in several stages and punching a valve seat in the bottom of the cup. A shoulder is formed in the housing by means of a profiled drawing mandrel and by fitting a washer against the shoulder to serve as a backing member for a tapered spring.
