Abstract

The cylinder and piston components are axially displaceable in separate stages relatively to one another for activation of separately movable expeller plates (2,3). The plates (2) located foremostly in an axial direction are connectable with the displacement piston (7) and is formed by a telescopic piston with connection for releasable coupling of the piston parts (10,11) in an extended position, independently of the rear expeller plate (3) connection with and activation by the displacement cylinder (6). Between the piston (7) and the cylinder (6) are means for their releasable connection, formed by a number of radially movable force transmission pieces, which in a position radially extended from the piston are held in a freely coupled position, but in the radially drawn-in position are received in a recess (28) in the piston for force transmission and cooperate connection of the cylinder and the piston (6,7).
