A valve assembly (3) comprising a valve body (5), a valve needle (7) and a first guiding element (19) for axially guiding the valve needle (7) is disclosed. The first guiding element (19) is bottle shaped and is axially deformable at least in part. It is f...

An electromagnetic valve (10) includes a valve member (14) located within a valve body (16), and adapted to move in slidable manner within a bore defined in the valve body (16). The movement of the valve member (14) is selectively allowing fluid/fuel flow ...

The injector (1) has a linearly movable valve needle (7) e.g. hollow or solid needle, for opening and closing a combustion-chamber side injection aperture (5) of housing (2). A solenoid (11) linearly moves an armature (13). A sleeve is attached to the arma...

Valve assembly (11) for an injection valve (10), comprising a valve body (14) including a central longitudinal axis (L), the valve body (14) comprising a cavity (18) with a fluid inlet portion (42) and a fluid outlet portion (40), the fluid inlet portion (...

Valve assembly for an injection valve, injection valve and method for assembling a valve assembly of an injection valve. The invention relates to a valve assembly (11) for an injection valve (10) and a method for assembling a valve assembly (11). The valve...

Injection valve (2) comprising a valve body (4) with a central longitudinal axis (L) and a first cavity (16) and a second cavity (18). The injection valve (2) further comprises a valve needle (10) being axially moveable at least in the second cavity (18) a...

During the duty cycle of an injection valve (10), pressure waves are generated inside the fluid chamber (14) of the injection valve (10) that deteriorate the operation of the injection valve (10). In order to absorb theses pressure waves, a bellows (22) is...

The present invention provides a fuel injector including a housing, an armature (46), an armature bias spring (32), a needle (68), and a seat (64). The armature (46) has an armature passage (54) including a first portion (90) and a second portion (92). A f...
