PROBLEM TO BE SOLVED: To effectively exert a bleeding function without depending on pressure to be sensed by a pressure sensitive part in a control valve for a variable capacity compressor with the sensitive part.SOLUTION: A control valve 1 comprises: an auxiliary valve element 36 which is integrally provided at an end of a power element 6 opposite to an actuation rod 38, attached, detached to an auxiliary valve seat 34, opens, and closes an auxiliary valve; and a spring 40 which energizes the auxiliary valve element 36 in a valve closing direction. Then, a load of the spring 40 is set so that the auxiliary valve element 36 is seated on the auxiliary valve seat 34 to function as a fixed end of the power element 6 in a state that control current of a main valve is supplied to a solenoid 3, the auxiliary valve element 36 is separated from the auxiliary valve seat 34 to integrally displace with the power element 6 when current equal to or more than a setting value larger than the control current is supplied to the solenoid 3. |
