Abstract
A device for actuating a plurality of hydraulic control cylinders having a pressure regulating valve with a first and a second pressure regulating output, a first selector valve connected downline from the pressure regulating outputs, a second selector valve connected downline from the first selector valve, having a plurality of individual pressure outputs, where the second pressure regulating output is optionally assignable through the first and second selector valves to one of the individual pressure outputs, and the particular individual pressure outputs that are not assigned to the second pressure regulating output are assignable to the first pressure regulating output.
Claims8
A device (1) for actuating a plurality of hydraulic control cylinders (15, 17, 19, 21, 23, 25, 27, 29), comprising:
- a pressure regulating valve (41) with a first and a second pressure regulating output (45, 47);
- a first selector valve (51) connected downline from the pressure regulating outputs (45, 47);
- a second selector valve (53) connected downline from the first selector valve (51), with a plurality of individual pressure outputs (33, 35, 37, 39);
- wherein the second pressure regulating output (47) is optionally assignable through the first and second selector valves (51, 53) to one of the individual pressure outputs (33, 35, 37, 39), and the individual pressure outputs (33, 35, 37, 39) that are not assigned to the second pressure regulating output (47) are assignable to the first pressure regulating output (45).
A hydraulic shift transmission comprising a device (1) for actuating a plurality of hydraulic control cylinders (15, 17, 19, 21, 23, 25, 27, 29), including:
- a pressure regulating valve (41) with a first and a second pressure regulating output (45, 47);
- a first selector valve (51) connected downline from the pressure regulating outputs (45, 47);
- a second selector valve (53) connected downline from the first selector valve (51), with a plurality of individual pressure outputs (33, 35, 37, 39);
- wherein the second pressure regulating output (47) is optionally assignable through the first and second selector valves (51, 53) to one of the individual pressure outputs (33, 35, 37, 39), and the individual pressure outputs (33, 35, 37, 39) that are not assigned to the second pressure regulating output (47) are assignable to the first pressure regulating output (45).
