The invention relates to a pneumatic working cylinder with pneumatic end-position damping In order to dampen the piston movement in a working cylinder as uniformly as possible before the end position is reached, a longitudinal bore (21) and several transverse bores (20) connected to the longitudinal bore (21) are provided, as shown in Fig. 1, in a damping piston (7) arranged coaxially on the main piston (4). When the damping piston (7) plunges into a damping space (blind hole 9) provided with a sealing element, the longitudinal bore (21) and the transverse bores (20), after crossing the sealing element, gradually connect the damping space (9) to the working chamber to be vented. High pressure peaks in the damping space and thus uncontrolled spring-back of the damping piston (7) and thus also of the main piston (4) are prevented by this measure. <IMAGE>
