Rotary piston machine or power unit - has six pistons arranged in star formation about seventh piston, creating small and large working chambers on rotation

摘要

The piston machine has a set of six triangular rotary pistons arranged in the form of a star about an inner (central) triangular rotary piston of the same size. On the rotation of all the pistons, alternately enlarging and reducing spaces (chambers) are created which are used as working chambers. The arrangement can be constructed and installed as a working machine or as a power unit. In the latter case the design can be for a two-stroke or four-stroke petrol or diesel engine. ADVANTAGE - Has a compact construction giving a uniform scavenging action and improved exhaust gas values.
