ABSTRACT:
The actuator comprises a piston (34) which has a stepped portion (36) formed with an annular groove (38) at its end projecting out of a cylinder (16). An annular protective sheet (50) is slipped on the stepped portion (36) and it comprises at its radially inner edge (52) inwardly projecting, resilient tongues (54) which are arrested in the annular groove (38). An annular elastic sleeve (46) is arranged behind the protective sheet (50), thereby being protected against heat, and provides sealing as against the piston (34), on the one hand, and the cylinder (16), on the other hand.
