摘要： A rotary end face seal assembly to seal a fluid under pressure includes a pair of annular mating ring seal faces (24, 32) with one of the faces defining a sealing interface between radially inner and radially outer peripheral edges (36, 38). A plurality of hydro-pad recesses (44) are formed radially inwardly from the peripheral edge of one of the seal faces at the pressure side of the seal assembly at peripherally spaced intervals and a plurality of feeder grooves (60) are formed radially inwardly from the same peripheral edge of the seal face between at least some hydro-pad recesses. The radial extent of the feeder grooves is longer than the radial extent of the hydro-pad recesses. In one form a feeder groove is disposed between adjacent hydro-pad recesses. In another form a feeder groove is disposed between adjacent pairs of hydro-pad recesses.
