  • Continuously operating fuel injection system
    Patent number: 4523568
    Abstract: A continuously operating fuel injection installation which includes an air-quantity measuring device in the suction pipe and a fuel-quantity distributor controlled thereby, is equipped for use with a multi-cylinder aircraft engine, with an auxiliary device that serves to achieve the best possible power output, fuel economy and flight safety; for that purpose, a height control pressure regulator is connected to the control pressure line leading to the fuel-quantity distributor in parallel to a warm-up regulator, which meters the control pressure and therewith the fuel admixture corresponding to the air density changing with temperature and pressure; by interconnecting a fixed throttle between the control pressure line and the fuel return line to the fuel tank, an emergency operation of the engine is assured in case of failure of both regulators.

  • Device for detecting the failure of a sensor
    Patent number: 4521769
    Abstract: A device for detecting the failure of a sensor which is installed on machine elements which are fitted with rotating parts, a reference signal being obtained from the output signal of the sensor, the reference signal being compared, in a comparator, with the output signal of the sensor, the output pulses from the comparator being employed to trigger a retriggerable one-shot multivibrator circuit.

  • High pressure transducer
    Patent number: 4519254
    Abstract: A high pressure transducer, especially for ballistic pressure measurements, with a body member and a sensor part, the body member can be screwed into a threaded mounting bore provided in a structural component, whereby the body member comes into sealing contact with its sealing surface against a seating surface of the mounting aperture. The body member is provided with a recess, into which projects an extension on the sensor part to be secured along its end-face on the body member. An annular gap is provided between the extension of the sensor part and the recess in the body member, which causes the force flux lines produced by the sealing forces not to pass through the sensor part so that the latter remains unaffected by changing conditions of the force flux lines, i.e. by the prevailing tightening torques.
