Problems solved by technology

However, this involves a special shaping of the main body which has a negative effect on the manufacturing costs, as well as a negative effect on the mounting of the sealing disc
In addition, according to this design, only one of the two axial end faces of the sealing disc is provided as a sealing face suitable for cooperating with the valve seat, which is not conducive to changing the configuration of the multi-way valve

Embodiment Construction

[0034] The multi-way valve designated as a whole with the reference number 1 contains a valve part 4 which is arranged linearly displaceable in the valve chamber 2 of the valve housing 3 . A possible movement of the valve part 4 is also referred to below as a switching movement 5 and is indicated by a double arrow in the drawing.

[0035] In order to generate the switching movement 5 , the multi-way valve 1 is equipped with a drive 6 , which is preferably of the electrically actuatable type. The electrical contact mechanism 7 of the drive device 6 allows the transmission of electrical actuating signals for actuating the drive device 6 as required, which in turn then positions the valve part 4 accordingly.

[0036] The multi-way valve 1 is preferably an electro-fluid pre-controlled structure type. Correspondingly, the valve element 4 is a component of the fluidically actuatable main valve 8 of the multi-way valve 1 , and the drive device 6 is an electrically actuatable pilot v...

Abstract

Provided is a multi-port valve (1) equipped with a valve member (4) movable in a valve chamber (2) of a valve housing (3). The valve member has a main body (23) and an elastically-deformable formed sealing plate (24) fixed thereto. The sealing plate (24) axially cooperates with at least one annular valve seat (15, 16) opposite thereto and arranged on the valve housing (3). Thus, in order that the sealing plate (24) is not deformed excessively during its engagement with the valve seat (15, 16) by fluid forces acting on it, the sealing plate (24) is enclosed exclusively by a supporting ring (42) just fixed on its radial outer circumferential surface.

Description

technical field [0001] The invention relates to a multi-way valve with a valve housing, in which a valve cavity is formed, in which a valve element is arranged, the valve element can move axially during a switching movement, The valve element has a main body, the main body has a peripheral outer circumferential surface, the main body has at least one elastically deformable annular sealing disc protruding radially relative to the outer circumferential surface, and the sealing disc has two axial end faces facing each other, In this case, at least one axial end face is located axially opposite an annular valve seat which is supported relative to the valve housing, which surrounds the overflow opening and can be closed with its two The end face rests on the sealing disc, and the overflow opening connects the two valve cavity parts of the valve cavity. Background technique [0002] Known from DE 20 38 846 A is a multi-way valve constructed as described above, where it has a valv...
