Abstract
PURPOSE: To increase the volumetric efficiency of the compressor and improve the durability thereof by sporadically providing depressions on the outer peripheral surface of a piston and applying a resin film on the outer peripheral surface.
CONSTITUTION: A piston 2 is fitted in a cylinder bore 1 of a compressor. A cylinder block 3 and the piston 2 forming the cylinder bore 1 are made of metal materials of systems having thermal expansivities in a substantially similar degree. Depressions are sporadically formed on the outer peripheral surface of the piston 2. A film 4 made of a resion is applied onto the outer surface of the piston 2, and the surface is formed into a cylindrical surface having no depression nor projection. Upon driving of the compressor, the sliding operation is performed between the inner peripheral surface of the cylinder bore 1 and the outer peripheral surface of the film 4.
