Abstract:
A flat-face coupler assembly for releasably coupling a fluid conduit and operative to release residual fluid pressure when disconnected from the conduit. The coupler includes a housing having a central stem centrally located having at least one end fixed in order to inhibit relative movement between the central stem and the coupler housing. The central stem defines a flat-face on a distal end that is engageable with a nose member of a male fitting. A tubular stem seat is supported for reciprocal sliding movement that at least surrounds a portion of the central stem and movable between at least two positions. In one position, the tubular stem engages the central stem in order to block communication between a port that communicates with the male fitting, and a main fluid chamber defined at least partially between the tubular stem seat and central stem. In this one position, the main chamber is also communicated with drain. When the male fitting is inserted into the coupler port, it moves the stem seat to a second position at which the port is communicated with the main chamber and fluid communication between the main chamber and drain is blocked. When the male fitting is disconnected from the coupler, the stem seat moves to its one position, closing off communication of the port with the main chamber while communicating the main chamber with the drain in order to discharge residual pressure. The flat-face coupler can be mounted in a manifold assembly and form part of a hydraulic system for operating a hydraulic attachment.

Claim (Index 6):
The flat-face coupler assembly of  claim 2  wherein said one end of said seat includes an inner chamfer that is sealingly engageable with a seal carried by an enlarged diameter portion of said distal end of said central stem.
