    Abstract: The invention relates to a gas valve for dispensing a gaseous fuel into an intake tract of an internal combustion engine, comprising an electromagnet (1) and an armature (2) which can be moved in a reciprocating manner and interacts with the electromagnet (1) and which, in the direction of a valve seat element (3) in which at least one passage opening (4) is formed, is subjected to the spring force of at least one closing spring (5). According to the invention, the armature (2) is designed as a disk-like composite element, which comprises at least two parts (1.1, 1.2, 1.3) preferably three parts, arranged concentrically with one another and located in one another, of which at least one part (1.1) is formed in the shape of a ring and forms a sealing face (6) that interacts with the passage opening (4).

    Abstract: The present invention refers to a valve assembly (2) for an injection valve (1), in particular for an injection valve (1) for injecting CNG, the valve assembly (2) comprising: a housing (3) providing a fluid inlet (4) and a fluid outlet (5) and a fluid path (6) extending between the fluid inlet (4) and the fluid outlet (5), a needle (7) within the housing (3) wherein the needle (7) is movable along a longitudinal axis (L) of the valve assembly (2), a first valve seat (10) and a first valve closing part (9), wherein the first closing part (9) is movable by the needle (7) between a closing position where the first valve closing part (9) is in contact to the first valve seat (10) for closing the fluid path (6) in between and an opening position where the first valve closing part (9) is spaced apart from the first valve seat (10) for opening the fluid path (6) in between. In order to improve such valve assembly (2) the invention suggests that the valve assembly (2) comprises a second valve seat (13) and a second valve closing part (12), wherein the second valve closing part is movable by the needle (7) between a closing position where the second valve closing part (12) is in contact to the second valve seat (13) for closing the fluid path (6) in between and an opening position where the second valve closing part (12) is spaced apart from the second valve seat (13) for opening the fluid path (6) in between. The Invention also refers to an injection valve (1) comprising a valve assembly (2) according to the invention.

    Abstract: Um bei einem trockenlaufenden Gasventil mit elektromagnetischer Betätigung hohe Öffnungsgeschwindigkeiten erzielen zu können, ist vorgesehen, den Angriffspunkt des Magnetankers 22 und den Anschlag am radial innen liegenden Führungsbereich 16 des Ventilelements 2 anzuordnen. Damit kann das Ventilelement 2 aufgrund der sich ergebenden reduzierten Durchbiegung kompakter und leichter gebaut werden und der Restluftspalt reduziert werden, was höhere Öffnungsgeschwindigkeiten ermöglicht.
