Abstract

A magnetic valve includes a valve component and a valve body that engages around a region of the valve component in a hood-like manner and in a sealing manner in at least one sealing region. A flow chamber is formed between the valve body and an end face of the valve component. The valve component has an axially running through-channel with a constant cross-section which passes through the end face and which opens into the flow chamber so as to form an axial duct for a fluid. The valve body has a through-opening that is fluidically connected to the flow chamber and is configured to be closed by a closing element that is movably arranged on a valve body face that faces away from the flow chamber. The end face is configured as a type of lip seal ring.

First claim

The invention claimed is:

1. A magnetic valve, comprising:
a valve component having an upper end portion;
a valve body surrounding the upper end portion of the valve component in a hood-like manner and in a sealing manner in at least one sealing region; and
a flow chamber defined by the valve body and the upper end portion of the valve component,
wherein the valve component has an axial through-channel which passes through the upper end portion and opens into the flow chamber to form an axial passage for a fluid, the through-channel having a constant cross section,
wherein the valve body has a through-opening that is fluidically connected to the flow chamber, the through-opening configured to be closed by a closing element that is movably arranged on a side of the valve body which faces away from the flow chamber, and
wherein the valve component includes a depression formed in the upper end portion, the depression spaced apart a first radial distance from the through-channel and spaced apart a second radial distance from the at least one sealing region.

2. The magnetic valve of claim 1 , wherein:
the valve component has a lower end portion arranged opposite the upper end portion, and
a rigidity of the valve component at the upper end portion is less than at the lower end portion due to the depression.

3. The magnetic valve of claim 1 , wherein the depression is positioned radially inwardly of the at least one sealing region.

4. The magnetic valve of claim 1 , wherein the depression is positioned radially between the through-channel and the at least one sealing region.

5. The magnetic valve of claim 1 , wherein the depression is a groove that opens directly into the flow chamber.

6. The magnetic valve of claim 1 , wherein the depression is a circular groove.
