STRUCTURE FOR A CHECK VALVE OF A VARIABLE-CAPACITY COMPRESSOR FOR A VEHICLE CAPABLE OF PREVENTING THE INFLOW OF FOREIGN MATERIALS REMAINING IN AN AIR CONDITIONING SYSTEM INTO A COMPRESSOR

摘要

PURPOSE: A structure for a check valve of a variable-capacity compressor for a vehicle to prevent the inflow of foreign materials is provided to effectively prevent the inflow of foreign materials remaining in an air conditioning system into a compressor while the inflow of a refrigerant is not obstructed by installing a filter on the inner wall of a valve seat.;CONSTITUTION: A structure for a check valve of a variable-capacity compressor for a vehicle comprises a first refrigerant outlet(31), a pair of second refrigerant outlets(32), a third refrigerant outlet(33), a refrigerant guide groove(21), and a filter. The first refrigerant outlet is longitudinally formed in the front side of a cylindrical body part of a valve case. The pair of second refrigerant outlets is formed in both sides of the cylindrical body part. The bottom of the second refrigerant outlets is higher than the bottom of the first refrigerant outlet. The third refrigerant outlet is formed on the cylindrical body part while facing the first refrigerant. The bottom of the third refrigerant outlet is higher than the bottom of the second refrigerant outlets. The refrigerant guide groove inclines upward on the inner wall of a valve seat. The filter is closely fixed on the inner wall of the valve seat to prevent the inflow of foreign materials remaining in an air conditioning system into the valve case through a refrigerant inlet.;COPYRIGHT KIPO 2013
