Abstract: The specification describes a rotary piston compressor with a double-arcuate trochoidal casing track, with which a triangular piston, rotating on an eccentric shaft, makes constant sliding contact at its corners. Transfer flow pockets are provided via which the following working chamber already shuts off, and in the vicinity of the dead center position, is connected for a short time with the compression chamber coming in front of it. The transfer flow recesses are provided in at least one side part of the compressor, extend under its housing casing and extend so far inwards radially in its side wall that they are not swept by the sealing strip. Their timing edge, lying to the fore in the direction of rotation of the piston, is determined by the position of the preceding piston corner of the chamber located in the dead center position. Their timing edge, which is to the rear in the direction of rotation of the piston, is determined by the position of the same piston corner at the time of uncovering the inlet port following this preceding chamber.

Abstract: A delivery valve, especially for a rotary piston compressor, which valve is adapted to be inserted into an opening provided in the compressor housing and extending substantially parallel to the axis of the compressor housing. The compressor housing has a bore in which is fitted a sleeve which has tangentially directed valve slots and forms a valve seat. The sleeve surrounds a member which over its entire length has an approximately horseshoe shape. That portion of the horseshoe shaped part which is located opposite the open side thereof faces toward the valve slots and has a greater bending radius than the sleeve. The free ends of the horseshoe shaped part which define the open side of the horseshoe shaped part are bent back toward the outside of this part while the lateral flanks of the horseshoe part bear against the sleeve. The flanks of the horseshoe shaped part have tangentially directed lateral perforations in which are guided parallel strip-shaped cutouts or tongues of a resilient sheet metal the marginal portions of which are clamped into the bent back portions of the horseshoe shaped part, the arrangement being such that the cutouts bear against the sleeve in front of the valve slots when the valve is closed.

Abstract: A pressure valve arranged in a rotary piston compressor which valve is mounted in a passage or bore of the housing casing of the compressor. The last mentioned passage is axis parallel to the rotary piston compressor axis. The valve has a cylindrical cross section and can be inserted into the passage or bore parallel to the compressor axis behind an outlet opening in the track of the housing casing through a side wall of the compressor. The valve seat is formed by a longitudinally slotted tubular part which exerts a radially outwardly directed resilient force. The slotted tubular part comprises segmental valve opening slots extending parallel to the side walls of the compressor. Over the slots are located valve lugs or tongues which are cut from a thin-walled tube arranged with a precise fit in the tubular part while the roots of the valve lugs or tongues are connected to the thin-walled tube. An additional tube is with precise fit inserted into the thin-walled tube. Cut out of the additional tube are stroke-limiting lugs or tongues which are located behind the valve lugs or tongues and are curved toward the interior of the thin-walled tube, the roots of the stroke-limiting lugs or tongues being connected to the additional tube.

Abstract: A compound supercharged rotary piston engine device in which a rotary piston compressor is interposed between a pair of rotary piston engines to form a unit. A single shaft extends through the unit and has coaxial eccentrics for the engines and an eccentric displaced 180.degree. therefrom for the compressor. The compressor supplies primary combustion air to the engines and also supplies air thereto for afterburning uncombusted fuel entrained in the exhaust gases of the engines. The air supply from the compressor to the engines takes place in a set of passages in the walls which separate the compressor from the engines and the passages are under the control of the pistons of the device.
