Capacity control valve

A capacity control valve comprising:

• a valve housing that is provided with a suction port through which a suction fluid of a suction pressure passes and a control port through which a control fluid of a control pressure passes;
• a CS valve that includes a CS valve element which is axially driven by a solenoid and a CS valve seat which is provided between the suction port and the control port and is brought into contact with and separated from the CS valve element;
• and
• a biasing member configured to bias the CS valve element in a valve closing direction of the CS valve,
• wherein a space is formed inside the valve housing and partially defined by an axial end face of the CS valve element,
• the CS valve element is disposed between the space and the solenoid in an axial direction and between the suction port and the space in the axial direction,
• the CS valve is configured to open and close a communication between the control port and the suction port,
• the suction fluid flows into the space through the suction port,
• the CS valve element is provided with a through hole extending in the axial direction, and
• the space and the suction port communicate with each other by way of the through hole, and
• wherein the space is closed except that the space communicates with the through hole.
