ABSTRACT:
A capacity control valve where a valve section is caused to be in contact with and separated from a valve seat by a valve rod to control the flow rate of pressurized fluid. The capacity control valve includes a first valve rod having a valve section and having a first peripheral surface formed on its outer periphery, a first valve chamber having a valve seat that comes into contact with and is separated from the valve section and having a first path into which pressurized fluid flows, and a valve housing having a through-hole that is movably fitted on the first peripheral surface of the first valve rod. The through-hole of the valve housing has a first tapered surface diverging as it goes away in the axial direction from the first valve chamber.
