VARIABLE DISPLACEMENT TYPE SWASH PLATE COMPRESSOR

摘要

PURPOSE: A variable displacement type swash plate compressor is provided to allow clearance by forming a penetrating channel on a hub-bush assembly coupled to a driving axis to allow foreign matters to be discharged. CONSTITUTION: At least one foreign matter discharge unit is formed in a hub-bush assembly to discharge foreign matters generated during rotation. The foreign matter discharge unit is a foreign matter discharge hole(274) formed along a corner of a bush coupling groove(273) formed on a center of an axis coupling part(271) of a hub(270) to penetrate the hub. The foreign matter discharge hole extends clearance between an inside of the axis coupling part and a bush(280) coupled through the bush coupling hole. Foreign matters generated by interference or vibration are discharged through the foreign matter discharge hole penetrating the hub through the corner of the bush coupling hole. Reliability of a compressor is secured thereby as torque is kept constant by securing fixed clearance and excluding interference.
