<p>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.</p> |
