Abstract

In the pneumatic linear drive with a cylinder (1) and a piston (2), clamping bodies (3) are arranged in two peripheral grooves (2.1). The clamping bodies (3) can be put into a clamping position or into a free-running position by tilting. There are two rings of clamping bodies (3) at the piston which serve to lock the piston (2) in one or the other direction of movement. Allocated to each ring of clamping bodies (3) is a thrust ring (14, 15) which after being acted upon by compressed air tilts the clamping bodies (3) into their free-running position so that the piston (2) in the cylinder (1) can perform a linear movement in the released direction. The locking of the piston by the clamping bodies (3) in any position has the advantage that, in contrast to known linear drives, the entire piston area is available for being acted upon by compressed air. The two rings of clamping bodies (3) are acted upon via a servo-valve (6) and a control valve (5a, 5b) allocated to one ring each. <IMAGE>
