An arrangement for setting the piston stroke of a pressure medium-activated piston-cylinder means (1 ) of the type that comprises a cylinder (2) in which is placed an extended piston rod (12), one end of which extends out through an opening (7) in an end wall (6) that is part of the cylinder and to the second end of which is attached a piston, whereby the piston rod (12) can be displaced between an inner and an outer end position through the influence of the piston. The piston rod (12) comprises a first part (13) and a second part (21 ), one of which is taken up in the other in a manner that allows sliding, and a junction (18) provided with a groove (27) in the form of a screw, which junction can be rotated relative to the two parts (13, 21 ) but cannot be displaced axially relative to one of the parts, whereby the degree to which one part is taken up into the second part can be determined by rotating interaction with the junction (18). |
