Abstract
A coupling that permits a connection to be made to a fluid system with a minimum of included air, even though the coupled device is not pre-filled. The coupling is particularly advantageously employed as part of a sampler used to take fluid samples for analysis as to air content. It includes a valve housing, a valve seat slidable within the housing and a valve closure member slidable within the seat. A lost motion mechanism allows joint movement of the seat and closure member prior to disengagement of the seat from the closure member. The fluid passage by which fluid is withdrawn from the system extends through the closure member.
