Patent attributes
An oscillating piston engine comprises a housing in which at least one piston is arranged which can revolve in the housing about an axis of rotation which is fixed in relation to the housing, and which performs when revolving about the axis of rotation reciprocating pivoting movements about pivot axis extending perpendicularly to the axis of rotation between a first end position and a second end position, the at least one piston having a running element which runs, as the piston revolves about the axis of rotation, along at least one control cam which is configured in such a way that the pivoting movements of the at least one piston are derived from the revolving movement of the running element along the control cam. A second running element mounted to the piston and/or a negative-pressure source applying a negative pressure to the backside of the piston are provided for assisting the return of the piston from the first end position to the second end position of the pivoting movement of the piston.
