Abstract (en)
[origin: WO9002867A1] A reciprocating piston engine with a cylinder crankcase (5) with curved cylinder walls (4) and a circular internal cross-section has a reciprocating piston (7) with integrated connecting rod shaft (8) and a circular connecting rod eye (9) which acts as a counterweight. This allows the centre (1) of the piston to trace curves of given shape, which results in a floating movement of the reciprocating piston (7) with very small lateral forces. The larger lateral amplitudes which result require special sealing strips (14) with corresponding pressure springs (15).
