A stop member is provided to prevent the withdrawal of the plunger, and structure is provided to prevent the disengagement of the stop member from a valve body. Specifically, the valve body is formed with a detent, and a retainer which supports the stop member is formed with a detent which is engageable with the detent on the valve body. The retainer is disposed externally of the stop member, and the detents on both the valve body and the retainer are effective, when engaged, to prevent the disengagement of the stop member from the valve body.
