ABSTRACT:
A rotary piston internal combustion engine includes two side parts and a casing cover part with a trochoidal shaped dual-arc casing inner surfacing of a fluid-cooled housing. An eccentric shaft passes axially through the housing. A triangular piston is journalled on an eccentric of the eccentric shaft with three corners of the piston gliding along the casing inner surfacing in a continuous sliding engagement. A belt drive connects the eccentric shaft with a refrigeration compressor of the same type of construction as the internal combustion engine. A fan wheel is arranged and joined by a universal coupling joint as to a telescopic part that is nonrotatable although axially shiftable relative to a mating telescopic part connected with an output shaft of the internal combustion engine connected by a first universal coupling joint and connected by a second universal coupling joint relative to the fan wheel. The telescopic parts include a polygon cross section for the inner part and an outer part which surrounds the inner part with a corresponding polygon-cylindrical inner shape slidable in the axial direction as is necessary to take up vibration impacts between the internal combustion engine fixed in a tubular frame and the fan wheel mounted in the housing frame. A shift between cooling operation and heating operation is made possible via a vaporization valve so that cooling medium circulation can be returned to the refrigeration compressor brought to a standstill when the circulation is switched to heating operation.
