Abstract

In the appts. the front plates (5, 6) are connected with a piston (7), in the rear end (7A) of which radial (8), movably activatable recesses (10) are received in shape-matching recesses (10). A casing enclosing the piston has receiving openings (12) for piston parts (13) and radial receiving recesses for the respective coupling pieces. A housing enclosing the casing has an internal axially extending hole for receiving the piston and casing displaceable in it. Receiving recesses (17) are arranged in the housing. The effects of the expulsion device (1) firstly produces the outward thrust of both plates together and then only the rear plate after change of the coupling pieces (9) between the recesses. The piston is connected with the front plate by means of a bolt (20) extending from its rear end. The housing is divided and formed by two tubular parts screwable to each other. The parts can be locked to each other by a lock part (23).
