Abstract
The arrangement comprises a pressure medium cylinder (2) provided with two cylinder spaces (2a, 2b) and two pistons (3a, 3b), and a control valve (12). The control valve (12) can be placed in at least three control positions but in only one at a time. In each control position, the pressure fluid is arranged to affect both cylinder spaces (2a, 2b) of the cylinder (2) such that in the control position concerned, the pistons (3a, 3b) always settle in a certain predefined position.
