ABSTRACT:
In lieu of the customary concentric annuli upon which to receive a ported valving plate, the seat has a plurality of lands at a common radial distance inwardly from the periphery thereof. The separations between the lands, circumferentially, define additional, fluid flow paths which increase the efficiency of the plate valve in which the seat is employed. Too, as the lands are circumferentially non-continuous, unlike the known, concentric annuli, surface-tension adhesion of the ported, valving plate is greatly minimized.
