ABSTRACT:
An oscillating type piston is connected to an output shaft of an electric motor through a crankshaft. The piston is provided with a lip ring that slidingly contacts a cylinder. The motor is rotated forward and reversely by using a control circuit. Thus, different regions of the piston are subjected to a load during forward rotation of the motor and during reverse rotation thereof. Accordingly, wear of the lip ring can be distributed to different regions thereof.
