Cylindrical member is provided with an actuator therewithin so that the actuator may be held by the cylindrical member. A support member 051452225 is fixed in position by means of the counter member and the guide is inserted into a hole opened at a position below a lower end portion of the actuator. A lower end side of the actuator is engaged with an upper surface of the support member and a pressing spring is interposed between the support member and the engaging portion of the cylindrical member to press a valve body against a valve seat formed in the valve base, whereby closing the said valve so that the pressing spring may be compressed by an output of the actuator during the time when the actuator is acting to separate the valve body from the valve seat, whereby opening the valve.
