    摘要: In a rotary mechanism of the Wankel type, a sealing device for each of the apex portions of the rotor which sealing device comprises a seal blade disposed for reciprocation toward and away from the trochoidal surface of the mechanism housing and a pressurized fluid actuating means responsive to the angular velocity of the rotor and coacting with the seal blade to hold the latter out of engagement with the trochoidal surface at a predetermined rotor angular velocity.
