Embodiment Construction

[0023] The figures each show schematically a valve module 1 of an injection valve designed for use on a fuel cell or a gas engine of a motor vehicle and for regulating a fluid flow from an inflow side 3 to an outflow side 5 .

[0024] According to known designs, the gas injection valve can be constructed as a multi-part housing, in which a solenoid operating unit is arranged with a field coil which surrounds the described valve module 1 .

[0025] The valve module 1 contains a valve sleeve 7 which can be produced by deep drawing or other forming techniques and consists of a non-magnetic material. A soft magnetic valve armature 9 having a valve closing element 11 for cooperating with a valve seat 13 of a valve seat body 15 is arranged axially displaceable in the valve sleeve 7 .

[0026] In the embodiment shown, the valve seat 13 is formed on a valve seat body 15 which is inserted into the valve sleeve 7 and fastened thereto, for example by welding, the valve seat body 15 in th...

Abstract

The invention relates to a valve module for supplying in particular gaseous media to an internal combustion engine. The valve module has a valve sleeve (7) in which a valve armature (9) having a valve closing member (11) is guided so as to be axially moveable relative to a valve seat body (15), which has a valve seat (13) and is fixedly arranged in the valve sleeve (7), in order to set a fluid flow between an inflow side and an outflow side (5). Here, according to the invention, a sealing device (21) which is composed of at least two annular sealing beads (22, 22', 22'') is provided, and the sealing device (21, 21', 21'') is arranged with respect to at least one passage opening (17) such that the at least one passage opening (17) is situated between the sealing beads (22, 22', 22'') in the closed position of the valve module (1).

Description

technical field [0001] The invention relates to a valve module of the type defined further in the preamble of claim 1 for supplying, in particular, a gaseous medium to an internal combustion engine. Background technique [0002] Such a valve for controlling fluids is known from DE 103 19 920, where this known solenoid-actuated valve comprises a valve closing element which controls the fluid flow from the inflow side to the outflow side and is connected with the A valve seat configured as a flat seat, which is formed on the valve plate, acts together. [0003] In the region of the valve seat, the valve contains a sealing element which is arranged on the end face of the valve closing element and has one or more sealing lips. The sealing element can be annular and engage in a corresponding annular groove on the end face of the valve closure element. [0004] Such known injection valves or injection valves (Einblasventil) are designed especially for gaseous media, and they are...
