Abstract: A hydraulic switching device for use in a circuit comprises at least two movable drive units producing movement in a functional direction or a counter-direction. The drive units can be pressurized with a pressure medium via at least two connection lines. Externally controllable selector switches are provided for controlling the pressurization so that exactly one controllable selector switch is provided for each drive unit and at least two drive units are interconnected via logical AND and/or OR valve elements so that at least with introduction of force to the first drive unit in the functional direction, a force release of the second drive unit is possible, and with an introduction of force to the first drive unit in the counter-direction, an introduction of force to the second drive unit in the functional direction, in the counter-direction or a force release is made possible.

Abstract: A hydraulic switching device (1; 101) for use in a circuit (7; 107) that comprises at least two movable drive units (2; 3) with a first direction of movement in the functional direction or a counter-direction, where said drive units can be pressurized with a pressure medium via at least two connection lines (13, 26; 24; 31), whereby externally controllable selector switches (14; 15; 16) are provided for controlling the pressurization with a pressure medium, is designed so that exactly one controllable selector switch (14; 15; 16) is provided for each drive unit (2; 3; 6) and at least two drive units (2; 3) are interconnected via logical AND and/or OR valve elements (22, 25; 141, 142, 143, 144) so that at least with a resulting introduction of force to the first drive unit (2) in the functional direction (F), a force release of the second drive unit (3), and with an introduction of force to the first drive unit (2) in the counter-direction (G), an introduction of force to the second drive unit (3) in the funct
