Abstract

A safety device for constant-pressure injection valve of an internal combustion engine. This device blocks the main supply line of the valve permanently and definitely in case the maximum admissible amount of injected fuel is exceeded or the control frequency for a given injected amount, less than the maximum admissible amount, is exceeded. The device is particularly applicable to diesel injection of the pressure-time type.
