Title: FUEL INJECTION VALVE
Abstract:
A fuel injection valve (31, 48), especially an injection valve for fuel injection systems of internal combustion engines, has an actuator which interacts with a first valve needle (35, 52). A first valve-closing body (36, 53) which is located on said first valve needle (35, 52) interacts with a first valve seat surface (37, 54) to form a first sealed seat (38, 55). A second actuator interacts with a second valve needle (39, 56), a second valve closing body (40, 57) which is located on the second valve needle (39, 56) interacting with a second valve seat surface (41, 58) to form a second sealed seat (42, 59).
