Embodiment Construction

[0035] exist Figure 1a A leveling valve 101 according to a preferred embodiment of the present invention is shown in and in Figure 1b Its enlarged cross-sectional view is shown in figure 2 A simplified illustrated embodiment is shown in . Therefore, about Figure 1a , Figure 1b with figure 2 Further descriptions are made in the same terms.

[0036] The leveling valve 101 includes a valve arrangement 103 for use in a plurality of application elements 205a, 205b (eg Figure 5Shown) and the pressurized air source 207 or discharge port 3 directs air. The valve arrangement 103 is preferably a valve disc arrangement. 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. The first valve disk 107 and the second valve disk 109 are rotatable relative to each other. The first valve disc 107 is...

Abstract

The invention relates to a leveling valve for discharging and supplying fluid, specifically to a leveling valve (101) for discharging and supplying air from and to a plurality of utilization elements(205a, 205b), in particular pneumatic suspension bellows, the leveling valve comprising: a valve arrangement (103) for directing air between a source (207) of pressurized air, an exhaust port (3) andsaid utilization elements, a supply port (1) in fluid communication with the valve arrangement (103) and the source (207) of pressurized air, and an exhaust port (3) having an exhaust air channel (a)for discharging exhaust air. In particular, the invention suggests that the exhaust port (3) comprises at least one air-permeable damping element, which is at least partly positioned within the exhaust air channel (a).

Description

technical field [0001] The invention relates to a leveling valve for exhausting air from and supplying air to a plurality of application elements, in particular pneumatic suspension bellows, the leveling valve comprising: valve means, said valve means means for directing air between a source of pressurized air, a discharge port, and the application element; and a supply port in fluid communication with the valve means and the source of pressurized air; Exhaust passage for exhaust. Background technique [0002] Leveling valves of the aforementioned type are known, for example, from WO 2010 / 089089 or EP 2 806 194 A1. [0003] Leveling valves of known type are 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 air suspension bellows of the vehicle, it is necessary in certain cases to i...
