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 10):
A flat-face coupler assembly for releasably coupling pressurized fluid conduct to a fluid pressure operated attachment, comprising:\n a) a coupler housing; b) a central stem centrally held within said housing, at least one end of said central stem being rigidly held to inhibit relative movement between said central stem and a body member of said coupler assembly; c) said central stem defining a flat-face on a distal end of said central stem, said flat-face abutably engageable with a nose member forming part of a male fitting that can be releasably connected to one end of said coupler assembly, said one end of said coupler assembly defining a fluid port for receiving or discharging pressurized fluid; d) a tubular stem seat supported for reciprocal, sliding movement within said coupler housing, said stem seat surrounding at least a portion of said central stem, said tubular stem seat being movable between at least first and second positions; e) a main fluid chamber at least partially defined between said central stem and said tubular stem seat, said main fluid chamber communicating with a second port spaced from said first port, said second port adapted to receive pressurized fluid for delivery to said main chamber or for discharging pressurized fluid from said main chamber; f) one end of said tubular stem seat operative to control fluid communication between said first port and said main chamber, said one end of said tubular stem seat engageable with said distal end of said central stem to block communication between said first port and said main chamber, while concurrently communicating said main chamber with a drain passage; g) said tubular stem seat including an abutment that is engageable by a portion of said male fitting such that said tubular stem seat is moved to its second position as said male fitting is connected to said coupler; h) said tubular stem seat being configured to block communication between said main chamber and said drain passage when said tubular stem seat is in its second position, whereby said main chamber is connected to said drain passage when a male fitting is not connected to said coupler and said first port is fluidly connected with said main chamber while said main chamber is not in fluid communication with said drain passage when said male fitting is attached to said coupler.
