ABSTRACT:
A fluid coupler having a female coupling member with an incorporated valve and a male coupling member for detachable insertion into one end portion of the female coupling member. The female coupling member has an annular flange which projects inwardly thereof to define a valve seat and a head portion having a diameter larger than the inside diameter of the annular flange and cooperative therewith to form the valve. A compression spring biases the valve member forwardly into a closed position. When the male coupling member is inserted, the valve member is biased against the force of the compression spring to open the valve and allow fluid flow from the valve into the male coupling member.
