Abstract

PURPOSE: To prevent contamination of the working volume from foreign matter and lubricants by coupling a piston having a dynamic clearance seal to a crankshaft to be driven rotatably and air-tightly sealing the volume housed by the crankshaft from the working volume. CONSTITUTION: The crankshaft of a motor 32 housed within a housing 30 is axially supported by bearings 36, 38 and the volume 41 housing the crankshaft 34 and the space housing the motor 32, are sealed air-tightly by a fixing seal 40. Furthermore, within the housing 30, two piston sections 48,54 are integrally fitted and the piston section 48 is coupled to the crankshaft 34 by way of a con rod 42. In this instance, the piston section 54 is formed by providing a labyrinth seal and the like as a dynamic clearance seal 62. Between the flange 68 of a sleeve 50 and a butt 70 of a sleeve 56, the opening end of a bellows 66 for sealing the working volume 58 from the volume 41 is made to hold securely the flange part.
