Patent attributes
A valve for supplying pressured air to vehicle air bags, includes a shuttle (20) with a valving member (80) having a precision polished seal surface (86) that presses against a precision polished sealed-against housing lower surface (50) of a housing (14) that confines the shuttle to sliding left and right. A recess (90) in the valving member can connect first and second holes (52 and 56, 58) in the housing lower surface, or isolate the holes from each other. The shuttle includes a shuttle frame (70) with a vertical bore (74) that receives a guiding part (82) of the valving member. A conduit extends from the valving member recess to a sealed region (102) at the top of the vertical passage to pressurize the sealed region with pressured air, to push down the valving member against the housing lower surface.
