Fuel injector valve

The valve (1) has a housing (2) comprising a housing part (3) and a throttle plate (4), and a control valve body (11) arranged in a control valve area (9) of the housing part. A sealing sleeve (20) is arranged at the body, and acts together with a valve seat surface (21) of a seal seat (22). The body has an outer thread (27), and the sealing sleeve has an inner thread (28), where the outer thread stays in engagement with the inner thread. The body is adjustable along a longitudinal axis, where a connection between the valve area and a low pressure area (10) is controlled by the seal seat.
