Abstract

Fuel-injection valve (1) comprises a valve (18) with a corrugated washer (21) at least partly surrounding the periphery of a bolt section (20) of a valve bolt (24). The corrugated washer impinges upon the valve bolt in the direction of a starting position in which the connection between a valve chamber (17) and a low-pressure region (36) via a discharge orifice is closed and the connection between a high-pressure region (14) and the valve chamber via a bypass channel (19) is open. Preferred Features: The corrugated washer is made of sleeve-shaped sheet metal.
