An improved rotary mechanism of the type having elongated seals for sealing the interface between a housing and a rotor mounted for movement therein, the seals being of the type which sealingly engage a relatively movable surface moving in a direction substantially longitudinally of the seals. The seals are provided with a plurality of recesses on both sides of the sealing surface along the length thereof, with the recesses on one side being staggered with respect to the recesses on the other. The sum of the width of adjacent recesses on opposite sides is substantially equal to or greater than the width of the sealing surface of the seal if the recesses were not present.
