Abstract
A rotary piston compressor of trochoidal type construction with a 1:2 step-up transmission gearing and operating in slip contact. The compressor has a side inlet with an inlet port control edge located in leading direction of piston rotation. A piston edge portion moves ahead and coincides with the inlet port control edge before the piston is located in its dead center position. A peripheral outlet port is provided having a control edge. A follower piston lobe at the same time traverses the peripheral outlet port to uncover it. The control edge of the inlet port which trails in the direction of rotation coincides with a trailing piston edge portion when the follower piston lobe is behind the outlet port in the direction of rotation.
