Embodiment Construction

[0030] figure 1 shows an equivalent diagram of an exemplary level control system 1 with a pressure medium supply device 3 which in this embodiment comprises a Pressure generating assembly 5. In principle, a hydraulic pressure medium supply is also conceivable.

[0031] A supply valve 17 is arranged downstream of the pressure medium supply device 3 in the direction of a plurality of support assemblies 9 - 15 , such as pneumatic springs. Functionally arranged between the supply valve 17 and the support assembly 9-15 is a single distribution valve 19 as part of a complete valve assembly 17, 19 comprising only the The supply valve 17 and the distribution valve 19. At least three support assemblies can be selectively actuated by means of the distribution valve 19 in order to adjust, for example, the horizontal position of the vehicle cabin.

[0032] The supply valve 17 is designed as a 3-position / 3-way directional valve and has a blocking position “b” in the direction of the di...

Abstract

The invention relates to a pressure medium supply device comprising a certain number of valves which are connected to the pressure medium supply device by means of a connecting line, two individuallyswitchable valves being arranged in a common housing.

Description

technical field [0001] The invention relates to a pressure medium supply device according to the preamble of claim 1 . Background technique [0002] In the case of pressure medium supply devices, for example for chassis or cabin mounts, the individual components are supplied by different manufacturers and fixed in defined positions during assembly. The pressure medium supply is partly a component of an active system which is often supplied as an equipment option. There is therefore considerable assembly effort between simple passive systems, such as mechanical cabin mounts, and active, adjustable cabin mounts. However, both systems must often be able to be assembled on one production line. Contents of the invention [0003] The object of the present invention is to further develop a pressure medium supply device in order to reduce the assembly effort to a minimum. [0004] The object is achieved in that at least two individually switchable valves are arranged in a commo...
