    摘要: 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.

    摘要: A pump injector sends a premetered quantity of fuel to a needle type injector of the type including a piston and a discharge chamber. The injector includes a compression piston mechanically controlled by cam or eccentric having any form. The compression piston compresses fuel within a compression chamber. An injection piston is activated exclusively by the pressure within the compression chamber, opposed by an opposing return spring. The injection piston in turn compresses the fuel in an injection chamber designed to feed the injector. A pressure regulator limits the pressure in the compression chamber to a high, preset value independent of the speed and load of the engine.
