CONTROL VALVE FOR A COMPRESSOR WITH A VARIABLE CAPACITY, CAPABLE OF INCREASING THE PERFORMANCE OF THE COMPRESSOR BY PREVENTING AN OPERATION DELAY CAUSED BY LIQUID REFRIGERANT

摘要

PURPOSE: A control valve for a compressor with a variable capacity is provided to improve initial operation performance by preventing an operation delay caused by liquid refrigerant.;CONSTITUTION: A control valve for a compressor with a variable capacity comprises a valve body(100), an operating unit(300), and a driving unit(200). A control flow path is opened in a normal mode, and first and second additional flow paths are closed to control an angle of a swash plate by adjusting the pressure of a crank chamber. The refrigerant in a discharge chamber flows into the crank chamber. The operating unit moves when the pressure of the crank and suction chambers are abnormally high so that the first and second additional paths are connected each other to be opened. The refrigerant in the crank chamber flows through the first and second additional paths, and is supplied to the suction chamber to lower the pressure of the crank chamber.;COPYRIGHT KIPO 2013
