Abstract
A variable displacement compressor includes a cylinder block having cylinder bores and a center bore, a drive shaft extending into the center bore through a crank chamber, an adjusting screw threaded into the center bore for axially supporting one end of the drive shaft via a thrust bearing and adjusting an axial gap of the thrust bearing, a plurality of pistons provided in the cylinder bores and moved reciprocally with the rotation of an inclined plate, and a belleville spring interposed between the thrust bearing and the adjusting screw. The adjusted spring force of the belleville spring is always added to an axial force applied to the drive shaft. The repeat of contact/release between the rotor and the thrust bearing, that is caused by the periodic increase/decrease of the compression reactive force, is prevented, and the axial vibration of the drive shaft is prevented.
