Document Type and Number:
WIPO Patent Application WO/2013/058598
Kind Code:
A3
Abstract:
The present invention relates to a control valve for a compressor which is coupled with a swash plate arranged at a crank chamber, compresses a refrigerant that has been suctioned into a suction chamber using a plurality of reciprocating pistons, and discharges the compressed refrigerant to a discharge chamber.
The control valve for the compressor comprises: a valve body having an internal space; an operating unit which can reciprocate in the internal space of the valve body; a driving unit which is provided in the internal space of the valve body to enable the operating unit to reciprocate according to the current applied from the outside; an air supply flow channel in which a bleed valve chamber is formed therein and which connects the crank chamber with the discharge chamber between inner walls of the valve body; a first bleed flow channel which connects the crank chamber with the suction chamber between the inner walls of the valve body; a second bleed flow channel which is formed along an axial direction through the bleed valve chamber and is connected to the first bleed flow channel; an air supply valve unit which is connected with the operating unit to enable the operating unit to reciprocate, and selectively opens and closes the air supply flow channel and the first bleed flow channel; and a bleed valve unit which is provided in the inside of the air supply valve unit and opens and closes the second bleed flow channel according to the pressure of the suction chamber. Thus, the present invention can stably perform operations by minimizing the influence on the crank pressure.
