A control valve has a valve housing (45). A valve chamber (46) and a pressure sensing chamber (48) are defined in the valve housing (45), respectively. A pressure sensing member (54) is located in the pressure sensing chamber (48). A pressure sensing rod (41) is slidably supported by the valve housing (45). A valve body (43) is accommodated in the valve chamber (46). An end of the pressure sensing rod (41) is connected to the pressure sensing member (54) and the other end of the pressure sensing rod (41) contacts the valve body (43). A solenoid chamber (63) is defined in the valve housing (45). A stationary iron core (62) is located between the valve chamber (46) and the solenoid chamber (63). A solenoid rod (40) extends through and is slidably supported by the stationary iron core (62). An urging force applied to the pressure sensing member (54) by an actuator through the solenoid rod corresponds to a target value of the pressure difference. The pressure sensing member (54) moves the valve body (43) such that the pressure difference seeks the target value. <IMAGE>
