摘要:
A control valve includes a valve chamber. A valve body is located in the valve chamber. A first regulator regulates the movement of the valve body. A first spring urges the valve body towards the first regulator. A sensing member divides a sensing chamber into a first pressure chamber and a second pressure chamber. The sensing member moves in accordance with the pressure difference. A regulator surface regulates the movement of the sensing member. A temporary chamber is formed between the sensing member and the valve body when the valve body is disconnected from the sensing member. The temporary chamber is connected to the second pressure chamber. A second spring urges the sensing member toward the regulator surface. An actuator applies a force to the valve body that is opposite to the force of the first spring and that of the second spring in accordance with commands from an external controller.
