Embodiment Construction

[0033] refer to Figure 1 to Figure 4 , shows a first preferred exemplary embodiment of a fluid valve 1 according to the invention. In this example, the fluid valve is a gas injection valve, which can be used to control the supply of gas into a combustion chamber of an internal combustion engine of a motor vehicle. The fluid valve 1 comprises a valve housing 2 which in this example has several parts and extends along a longitudinal central axis L from a fluid inlet 3 to a fluid outlet 4 of the fluid valve 1 . In this example, the fluid valve 1 comprises a first valve assembly 5 and a second valve assembly 6 adjoining said first valve assembly downstream with respect to the fluid passage direction FD. The first valve component 5 has a valve needle 7 and an electromagnetic actuator 8 . The valve needle 7 is displaceable in the cavity 9 of the valve housing 2 along the longitudinal center axis L (that is to say in the axial direction). The electromagnetic actuating device 8 ha...

Abstract

The invention relates to a fluid valve (1), which has a first valve assembly (5) having a valve needle (7) and an electromagnetic actuating device (8). According to the invention, the electromagneticactuating device (8) has an armature (10), which is coupled to the valve needle (7), and a pole piece (11). The armature (10) has an armature locating surface (15) on an armature locating side (14) opposite the pole piece (11), and the pole piece (11) has a pole piece locating surface (17) on a pole piece locating side (16) opposite the armature (10). For advantageous further development, according to the invention, the first valve assembly (5) has a deformable first ring element (19) and a deformable second ring element (20), wherein, when viewed along the longitudinal center axis (L), an inner contour (23) of the first ring element (19) extends outside an outer contour (24) of the second ring element (20). The invention further relates to a method for controlling the supply of fluid by means of a fluid valve according to the invention.

Description

technical field [0001] The present invention relates to a fluid valve, in particular a gas valve, comprising a valve housing extending along a longitudinal central axis from a fluid inlet to a fluid outlet and comprising at least one first valve assembly, wherein the first valve assembly has a valve a needle and an electromagnetic actuator, wherein the valve needle is movable in a cavity of the valve housing along the longitudinal central axis, wherein the electromagnetic actuator has an armature coupled to the valve needle and a pole part coupled to the valve housing, wherein the armature has an armature stop surface on an armature stop side opposite the pole part, and the pole part has an armature stop surface opposite the armature has a pole part stop surface on the pole part stop side. Background technique [0002] In the coming years, the proportion of pneumatic vehicles will increase more and more. However, the additional cost of additional pneumatic operation is an ...
