Valve for metering a fluid, in particular, a fuel injector

Abstract

The valve according to the present invention, in particular, a fuel injector, is characterized by having an improved sealing at its spray-side end. The fuel injector (1) includes an excitable actuator (15) for actuating a valve closing body (12), which together with a valve seat surface (14) formed on a valve seat body (13) forms a seal seat, and spray openings (4) formed downstream of the valve seat surface (14), and a valve seat support (10), which accommodates the valve seat body (13), forms a portion of a valve housing (22) and is fixedly connected to the valve seat body (13). A plastically deformable sealing element (45) is introduced into an annular gap (35) between the valve seat support (10) and the valve seat body (13) to avoid corrosion and damage of a weld seam (30). The fuel injector is particularly suitable for directly injecting fuel into a combustion chamber of a mixture-compressing spark ignition internal combustion engine.
