METHOD FOR LEAK TEST ANALYSIS OF ELECTROMAGNETIC CONTROL VALVE USING IN EXTERNAL VARIABLE DISPLACEMENT TYPE COMPRESSOR FOR AIR CONDITIONING CONTROL SYSTEM IN AUTOMOBILES

摘要

The present invention relates to an electromagnetic control valve (ECV) used for a variable displacement swash plate type compressor for a vehicle air conditioning system. The present invention provides a method to design a variable capacity type compressor electromagnetic control to design a variable capacity type compressor electromagnetic control valve for a vehicle air conditioning system based on a leakage analysis capable of performing a leakage test analysis inside a valve body from a discharge port (P_d) to a crankcase port (P_c) of a variable displacement swash plate type compressor electromagnetic control valve (ECV) for a vehicle air conditioning system; and designing an electromagnetic control valve based on the result. As such, the efficiency of a variable capacity type compressor is improved, and the overall performance such as ride comfort and fuel efficiency of a vehicle can be improved.
