1. A control valve, provided in a refrigeration cycle, for controlling a flow of refrigerant, the control valve comprising:
a body having a lead-in port through which the refrigerant is led in, a lead-out port through which the refrigerant is led out, and a valve hole formed in a refrigerant passage joining the lead-in port to the lead-out port; a valve element that opens and closes a valve section by moving toward and away from the valve hole; a drive section that generates a drive force used to open and close the valve section; a shaft one end side of which connects to a movable member of the drive section and another end side of which connects to the valve element, the shaft transmitting the drive force, generated by the drive section in a direction of axis line, to the valve element, wherein the shaft is so provided as to run through an insertion hole formed in the body; and a sliding mechanism that directly or indirectly applies a sliding resistance to an actuation of the valve element, wherein the sliding mechanism is configured such that a magnitude of the sliding resistance affected to the valve element is varied by a position of the valve element in the direction of axis line in the body. |
