ABSTRACT:
Gas seal characterized in that a groove is formed on a rotor or on a sealing piece slidably embedded in the rotor. An apex seal, outwardly urged in the radial direction, is slidably inserted in the groove and both ends of the apex seal are so supported by a corner seal block that the apex seal does not slip out of the rotor. At the same time the seal block assures air-tightness of the rotor ends, thereby effectively sealing the rotor against the housing.
