  • Injection valve with control valve
    Patent number: 6168132
    Abstract: The injection valve has a control valve with a control chamber in which a closing member is disposed. The closing member is pressed against a corresponding sealing seat by a pressure (e.g. fuel pressure) in the control chamber. The closing member merges into a rod that passes through a drain hole and is connected to a spring plate. The spring plate is preloaded against the housing by a compression spring in such a way that the closing member is pressed against an associated sealing seat. The closing member can be raised from the sealing seat by an actuator piston which rests against the spring plate.
