摘要:
A valve seat member is fixedly received in a lower end portion of an elongated body. The valve seat member has a valve seat and an injection port at its lower end portion. A valve element is axially movably received in the body. The valve element is fully lifted from a position where a valve portion formed on the lower end of the valve element sits on the valve seat to a position where an upper end portion of the valve element is brought into abutment with a stopper of the body. This fully lifted amount is determined by the thickness of a shim interposed between a first receiving surface of the body and a second receiving surface of the valve seat member. The lower end portion of the body and the valve seat member are welded over the entire periphery.
