A STUDY ON INNER FLOW PRESSURE CHARACTERISTICS OF AUTOMOTIVE VARIABLE DISPLACEMENT SWASH PLATE TYPE COMPRESSOR ECV

Vehicle air conditioner compressors have a great effect on the power efficiency and fuel efficiency of the vehicle. The ECV (Electromagnetic Control Valve) of the automotive air conditioner compressor must be precisely controlled. An understanding of the relevant functional elements of the ECV (Electromagnetic Control Valve) with the development of the technology should be done. The force, pressure, and temperature acting on the valve components are analyzed and applied to practical applications. In Variable Displacement Swash plate type Compressor, we analyze the refrigerant flow pressure characteristics inside the valve on the effect of valve activation.
