Embodiment Construction
[0030] figure 1 A first embodiment of the valve device according to the invention is shown, showing the housing 1 and the actuating part 2 . The operating element 2 has a lever 3 . The operating member 2 can be rotated relative to the housing 1 by operating the lever 3 . To this end, the actuating element 2 is mounted rotatably in the housing 1 and in a tubular part 7 . The tubular part 7 is connected to the housing 1 or formed integrally therewith. When the operating element 2 is actuated, it simultaneously moves the push rod 8 . The push rod 8 is used to transmit the rotary motion to the slide valve consisting of two ceramic discs 4, 5, which can be twisted relative to each other according to the rotary motion. The ceramic discs 4, 5 have a row of holes and channels which function as valves of the valve means. On one position of the valve device, free passage (travel position) is formed between the pneumatic connecting pipe 18 and the pneumatic connecting pipe 19, the ...

The invention relates to a valve device for manually varying the level of an air-sprung vehicle, having a housing (1) and having a manual operating element (2) which is moveable relative to the housing (1), wherein the operating element (2) can be set into various positions by means of a rotational movement and can be latched into predetermined positions by means of a mechanical locking device (12, 26), wherein the locking device (12, 26) acts between the operating element (2) and the housing (1). Proceeding from this, a valve device is specified which can be designed with or without a dead man function without a significant change to the construction being required for this purpose, and here, permits an automatic return into the drive position.; For this purpose, an unlocking device (13,22, 24, 27, 28, 34) is provided which removes the latching action of the locking device (12, 26) when an electrical and / or pneumatic signal is applied.
Description
technical field [0001] The invention relates to a valve device for manually changing the horizontal position of an air suspension vehicle. Background technique [0002] A valve arrangement according to the classification is disclosed by the applicant company as a so-called rotary slide valve. The disclosed rotary spool valve is used to control the raising and lowering of air-suspended vehicles, such as the raising and lowering of interchangeable car chassis and saddle trailer chassis. For this purpose, the rotary slide valve has a manually operated part in the form of a lever, which can be turned from the middle position into the first position by turning to the right and then into the second position by further turning to the right, and correspondingly by turning to the left into the third and fourth positions. Location. The intermediate position is used here as a driving position, in which the rotary slide valve pneumatically connects the air spring valve of the air susp...
