Problems solved by technology

In particular, valve seals that are continuously exposed to pressure or are continuously subjected to high temperatures or temperature changes can be very difficult to meet requirements in terms of robustness or lifetime, which can lead to shortened maintenance intervals or, in the event of a fault, functional out of order

Embodiment Construction

[0023] In the following figures, the same reference numerals denote the same or the same type of components.

[0024] figure 1 A first embodiment of the valve according to the invention is shown. The illustrated valve 10 comprises a valve housing 14 with a valve seat 12 , wherein a valve body 16 is located inside the valve housing 14 , which is movable relative to the valve housing 14 . The upper part of the movable valve body is designed as an electromagnetic actuation device 36 . The electromagnetic actuating device 36 can be designed, for example, as a simple permanent magnet and exerts a force for moving the valve body 16 by energizing a coil winding, not shown, arranged on the valve housing 14 . A space 18 is formed between the valve body 16 and the valve housing 14 , which is divided into regions by the seal 20 and the O-ring 30 at the sealing point 28 . The O-ring 30 can generally be made of an elastomer material here. The seal 20 arranged at the sealing point 28 co...

Abstract

The present invention relates to a valve (10) having a valve body (16) that is movable in a valve housing (14) opposite a valve seat (12), wherein a space (18) is formed between the valve body (16) and the valve housing (14), said space being partitioned or limited by means of at least one seal (20). The invention provides that the at least one seal (20) comprises a carrier element (22) made from metal.

Description

technical field [0001] The invention relates to a valve with a valve body movable relative to a valve seat in a valve housing, wherein a space is formed between the valve body and the valve housing, which space is separated or delimited by at least one seal. Background technique [0002] Valves, in particular pneumatic valves, generally have several seals for separating individual working chambers or individual functional chambers between the movable valve body and valve housing or for sealing the valve housing. The seal is usually realized as an O-ring or as a seated profile seal, respectively, from an elastomer material. However, elastomeric materials are subject to aging processes, which leads to a reduced resetting capacity under loaded conditions and the resulting leakiness of the seal. [0003] Especially in the field of commercial vehicles, robustness and a long service life, ie a long average operating life, are important prerequisites for operation. The average op...
