Low profile discharge check valve

摘要

A low profile valve for discharging pressurized air to a system for utilizing such pressurized air. The valve includes a housing (24) for mounting in or to an associated structure (14), and has at least one opening (22) through which pressurized air is directed to and from the valve. A piston (20) is located in the housing for axial movement therein, and the piston has a face portion (18) containing a seal (34) for sealing the piston against a fixed surface (16) of the associated structure. In addition, a spring (26) can be located about the piston for biasing the piston in the direction of the fixed surface.
