ABSTRACT:
Intake or exhaust reed valves of a compressor or vacuum pump have T-shaped flappers which are received in similarly T-shaped pockets so as to be substantially flush with the valve plate. A dirt trap groove is formed in each pocket adjacent to the hinge line of the flapper, a corner relief groove surrounds lands which support the flappers in their associated pockets above the groove, and the extending-part of each pocket widens in the direction away from the cross-part of the pocket. The mating T-shapes of a flapper in a pocket restrain the flapper in the pocket without interfering with the opening and closing motion of the flapper.
