Abstract: An inlet flow passage, a valve seat section, and a valve chamber are formed within a flow passage block. An operation chamber, a rocking chamber, and a drive chamber are formed within a case along a reference plane. A valve rod is brought into contact with and separated from the valve seat section by reciprocating through the operation chamber in an extending direction thereof. A piston rod reciprocates through the drive chamber in an extending direction thereof. A lever member is received in the rocking chamber and has a support shaft section. The distance between the center of the support shaft section and a second contact position where the piston rod contacts the lever member is set greater than the distance between the center of the support shaft section and a first contact position where the valve rod contacts the lever member.
