ABSTRACT:
A hydraulic cylinder (10) is disclosed comprising a cylinder housing (12) with a housing bore (14), a piston (16) held longitudinally displaceably in the housing bore, a piston rod (18) allocated to the piston and a fixing element (20) which before a first cylinder operation is detachably connected with the piston rod and fixes this in a predetermined stroke position in relation to the cylinder housing and is designed to release the piston rod in relation to the cylinder housing on the first cylinder operation. According to the invention, before the first cylinder operation the fixing element in a first position is detachably connected with a center area (22) of the piston rod and on cylinder first operation can be moved from the first position to a second position area (24), in particular stationary in relation to the piston rod, in which it can be fixed for further cylinder operations. The result is a simply designed hydraulic cylinder in which the fixing element provided for temporary tying of the piston rod in particular leaves untouched the end of the piston rod facing away from the piston and also does not hinder further the operation of the hydraulic cylinder.
