摘要:In lieu of the customary concentric annuli upon which to receive a ported valving plate, the at has a plurality of lands at a common radial distance inwardly from the periphery thereof. The parations between the lands, circumferentially, define additional, fluid flow paths which increa the efficiency of the plate valve in which the at 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.
