Abstract: The integrated air tool and pressure regulator assembly allows several air tools to operate from a single air compressor, using a simplified air hose distribution system. An operator may independently adjust the regulated pressure of the integrated air tool and pressure regulator assembly to compensate for varying working conditions. A greater air hose supply pressure may be used, as regulation of air pressure is accomplished at the integrated air tool and pressure regulator assembly. The increased air transport efficiency allowed by the integrated air tool and pressure regulator assembly of the present invention may provide for the use of smaller diameter hose, which may be lighter, more flexible, less costly, and the like.

Abstract: A head pressure relief assembly for relieving pressure in the head assembly of an air compressor may include an exhaust valve post formed in the head assembly and an exhaust valve assembly comprised of a flapper valve. An aperture may be formed through the exhaust valve post for venting the head assembly prior to start of the compressor assembly. The flapper valve is capable of engaging the exhaust valve post to close the aperture at least partially for preventing flow from the head assembly through the aperture during the compression stroke of the compressor assembly piston. A head pressure relief assembly may also include an aperture disposed in the head assembly, a connecting tube therefor, or a check valve.
