ECV controls the discharge of the Variable Compressor of the cooling cycle of the automobile A/C system. ECV receives the electrical signal [0-1.0A] from ECU and supplies of the flow (refrigerant) of discharge pressure [Pd] to the swashplate control case by proportional control using the suction pressure[Ps] / discharge pressure[Pd] of the

DCV (Discharge Check Valve) prevents the external movement of the refrigerant inside the variable swashplate compressor up to certain pressure level to maintain the swashplate at 0° when the variable compressor does not operate and to avoid performance degradation during

The valve was developed as cost-effective compared to existing models by improving the assembly method and changing the material [Brass -> PA46]. The valve shuts off the oil flow when the air-conditioner of the Variable Compressor is OFF with improved noise by assembling the SDD (Suction Damping Device) in the Rear Head Suction
