Abstract
Disclosed herein is a smart control valve for compressors that is capable of easily accomplishing compression and communication in a compression chamber of a cylinder, without performing the repetitive on/off operation of the compressor, to change the capacity of the compressor. The smart control valve comprises a valve body mounted on a cylinder including refrigerant inlet and outlet ports, a valve inlet port formed at the valve body and communicating with the refrigerant inlet port of the cylinder, a valve outlet port formed at the valve body and communicating with the refrigerant outlet port of the cylinder, an actuating groove disposed under the valve inlet port and the valve outlet port of the valve body, and an actuator disposed in the actuating groove for performing a linear reciprocating movement in the actuating groove as a solenoid is operated.
