Integrated pressure exhaust valve and fluid coupling

An integrated pneumatic coupling moiety and pressure exhaust valve comprising:

• a hollow body having a pneumatic pressure inlet port on one face of the body, an exhaust opening on the opposite face of the body, and a pneumatic pressure outlet port at an end of the body;
• a seal on the inlet port, a wing on the body, and a pocket complementary to the wing, the seal, wing and pocket conforming to SAE J318;
• and
• a check valve means in the body for
• (a) permitting air flow from the inlet port to the outlet port and preventing air flow from the exhaust opening when air pressure at the inlet port is greater than air pressure at the outlet port, and
• (b) permitting air flow from the outlet port to the exhaust opening and preventing air flow to the inlet port when air pressure is greater at the outlet port than at the inlet port.

An integrated fluid coupling moiety and pressure exhaust valve comprising:

• a hollow body having a valve chamber therein;
• a fluid inlet port to one side of the chamber from one face of the body;
• a fluid exhaust port from an opposite side of the chamber to the exterior of the body;
• a fluid outlet port from an end of the chamber to the exterior of the body;
• resilient seal means carried by the body about the inlet port;
• separate complementary male and female coupling configurations carried on the body at spaced locations about the inlet port adapting the body for fluid-sealing and locking engagement with a second coupling moiety having corresponding coupling configurations by placing the moieties in face-to-face engagement and twisting one relative to the other;
• and check valve means movable in the chamber in response to pressure differentials for closing the exhaust port from the chamber and for affording fluid flow from the inlet port to the outlet port when fluid pressure at the inlet port is greater than that at the outlet port, and for closing the inlet port from the chamber and for affording fluid flow from the outlet port through the exhaust port when fluid pressure at the outlet port is greater than that at the inlet port.
