ABSTRACT:
The invention provides a quick exhaust valve which allows compressed air to be smoothly supplied to and discharged from an air bag. The exhaust valve operates reliably even at low pressure or small quantity of air, and is capable of a quick exhaust of air. A valve body (11) has an opening (18) for connecting an exhaust port (17) to an air bag (A), and an inlet port (16) for compressed air. In this valve body (11), a valve member (13) comprising an opening/closing piece (20) for the exhaust port (17) and an opposing piece (21) for the inlet port (16) is arranged so it is movable in a direction to open and close the exhaust port (17). The opening/closing piece (20) and the opposing piece (21) of the valve member (13) are formed into an angle, preferably acute. This allows the opening/closing piece (20) to close the exhaust port (17) when the compressed air from the inlet port (16) is supplied. When the supply of compressed air is stopped, the valve member (13) is moved by the air bag side pressure, causing the exhaust port (17) to open. Thus, a quick exhaust can be attained.
