Problems solved by technology

[0006] A hitherto unresolved problem with leveling valves is that in rare cases, when the air pressure on the supply side of the leveling valve is disrupted, for example due to unforeseen damage to the fluid conduit, air can accidentally supply port egress, potentially crashing application components

Embodiment Construction

[0036] exist figure 1 , Figure 1a and Figure 1b A leveling valve 101 according to a preferred embodiment of the present invention is depicted in . The leveling valve 101 comprises valve means 103 for directing air between the plurality of application elements 205a, 205b and the source 207 of pressurized air or the discharge port 3 . The valve device 103 is a valve disc device. It comprises a first valve disc 107 and a second valve disc 109 . The first valve disc 107 and the second valve disc 109 of the valve arrangement 103 comprise respective flow portions forming a flow path for guiding air through the valve.

[0037] The first valve disc 107 and the second valve disc 109 are rotatable relative to each other. exist figure 1 In the preferred embodiment, the first valve disc 107 is mounted stationary inside the housing 140 of the leveling valve 101. The second valve disc 109 is mounted rotatably inside the housing 140 . The housing 140 of the leveling valve 101 inclu...

Abstract

The invention relates to a leveling valve for discharging and supplying air from and to a plurality of utilization elements (205a, 205b), in particular pneumatic suspension bellows, the leveling valve(101) comprising a valve arrangement (103) for directing air between a source (207) of pressurized air, an exhaust port (3) and said utilization elements (205a,205b), and a supply port (1) in fluid communication with the valve arrangement (103) and the source (207) of pressurized air. In particular, the invention suggests that a check valve (5) is mounted upstream of the valve arrangement (103),the check valve (5) being configured to allow fluid flow from the supply port (1) towards the valve arrangement (103) and to block fluid flow from the valve arrangement (103) through the supply port (1).

Description

technical field [0001] The invention relates to a leveling valve for discharging air from and supplying air to a plurality of applied elements, in particular pneumatic suspension airbags, the leveling valve comprising: valve means for Air is directed between a source of pressurized air, a discharge port, and the application element; and a supply port in fluid communication with the valve arrangement and the source of pressurized air. Background technique [0002] A leveling valve of the above-mentioned type is known, for example, from WO 2010 / 089089. Furthermore, a leveling valve of the above-mentioned type is known from EP2806194A1. [0003] Leveling valves of known type are commonly used to adjust the vertical clearance of a vehicle, such as a truck or other utility vehicle, relative to ground level. Depending on the load situation of the vehicle or depending on the dynamic forces acting on the applied element, such as the airbag of the vehicle's air suspension, it is ne...
