Abstract
A piston type compressor has a housing, a crank chamber and a drive shaft supported by the housing. A front restriction and a rear restriction are located in the housing. The front and rear restrictions restrict axial movement of the drive shaft. The front restriction restricts forward movement of the drive shaft. The rear restriction restricts rearward axial movement of the drive shaft. A first clearance is located between the rear end of the drive shaft and the rear restriction when the drive shaft is restricted by the front restriction. A second clearance is formed between the piston and a valve plate when the drive shaft is restricted by the front restriction and when the piston is in the top dead center position. The first clearance is narrower than the second clearance. The method of assembly the piston easily sets the first clearance.
