ABSTRACT:
A coupling member is provided for coupling a refrigerant line to a refrigerant port of a refrigeration system. The coupling member includes a generally cylindrical body member having a proximal end portion, a distal end portion, a radially inwardly facing surface defining an axially extending interior passageway, and a radially outwardly facing surface. The radially inwardly facing surface includes a circumferential fluid passageway portion. A radially extending fluid inlet passageway extends between the circumferential fluid passageway and the radially outwardly facing surface. An inner sleeve member is disposed in the axially extending interior passageway for axial movement therein. The inner sleeve member includes a wall having a radially inwardly facing surface defining an interior of the inner sleeve member, and a radially outwardly facing surface defining a boundary of the circumferential fluid passageway. A pin depressor member is disposed at least partially in the interior of the inner sleeve. A control cap member is adjustably positioned with respect to the body. A member is also provided for coupling the control cap member and the inner sleeve member so that adjustment of the axial position of the control cap member imparts axial movement to the inner sleeve member and the pin depressor member.
