Control valve for e.g. pump-nozzle fuel injector, has valve needle displaceably supported and partially moved in valve sleeve, A-valve formed between valve sleeve and valve needle, and B-valve formed between valve body and valve needle

摘要

The valve (10) has a multipart valve element (200) that is adjustably fixed to a valve body (100). The valve element has a valve sleeve (210) that is displaceably supported opposite to the valve body, and a valve needle (220) is displaceably supported and partially moved in the valve sleeve. An A-valve (230) is formed between the valve sleeve and the valve needle, and a B-valve (240) is formed between the valve body and the valve needle. The valve needle is adjustably supported at an end section (225) opposite to the valve sleeve in the valve body.
