Abstract
A female coupling member includes a body portion, a slideable sleeve positioned in the body portion and an axially extending stem valve sealingly engageable with the sleeve. Axial movement of the sleeve relative to the stem valve opens the female coupling member to the flow of fluid. The stem valve is provided with a cavity sized to receive a protruding nose of a male member to be attached thereto. The slideable sleeve and the stem valve are designed to receive the male coupling member including its flat insertion end and protruding nose with minimal air inclusion and minimal fluid loss upon disengagement.
