    Abstract: A fuel injection pump for internal combustion engines having a plurality of pump elements 2, 3 disposed in a line, the injection quantity control of which is effected via a control slide 9 that is axially displaceable on the pump piston 9 and by controlling a relief conduit 22-25 of the pump work chamber 18, the control slides 9 being surrounded by partial suction chambers 8 that discharge into a main suction chamber 10 receiving a torque shaft 12 for axially actuating the control slides 9. These partial suction chambers 8 each have a separate partial inflow conduit 39 of defined length and cross section, which communicates with an inflow conduit 33, so that the same volumetric flow is metered to each partial suction chamber in the manner of quantity division, while the main suction chamber 10 is retained and the torque shaft 12 is disposed in it.

    Abstract: An electric centrifugal switch is proposed, in particular for the purpose of safety shutoff upon attainment of a shutoff rpm for fuel injection systems, electrically controlled in an open- or closed-loop manner, of internal combustion engines, which is not vulnerable to rotary oscillations and which effects a rapid shutoff. The centrifugal switch comprises a centrifugal pendulum secured by means of a metal band bearing on a revolving carrier element and a switch attached to the housing and provided with a switching distance from an actuation pin. The centrifugal pendulum carries a flyweight mass on the end of a first lever arm extending substantially in the direction of the rotary axis, and its second lever arm extending at least approximately rectangularly to the rotary axis, is held together with a metal band of the band bearing in constant contact on a roll-off surface located on the carrier element by a restoring spring and, in a preferred embodiment, by means of a supplementary spring element. The inclination and spring rate of the obliquely positioned restoring spring are so designed that the increase in spring force when the centrifugal pendulum is swinging outward is less than the corresponding increase in centrifugal force.

    Abstract: A displacement pickup for detecting positions of an adjusting device, in particular an adjusting device of fuel injection pumps. In an advantageous manner, an adjustment of the displacement pickup can be performed with the aid of a cylindrical tang, which is displaceable and fixable in a through bore in the wall of a housing receiving the adjusting device and through the interior of which an adjusting device of the displacement pickup can be adjusted from outside the housing. In a displacement pickup advantageously embodied as a rotary potentiometer, a contact means of a resistor (Ra) of the resistance course of the potentiometer can thus be adjusted.

    Abstract: PCT No. PCT/DE83/00074 Sec. 371 Date Dec. 5, 1983 Sec. 102(e) Date Dec. 5, 1983 PCT Filed Apr. 21, 1983 PCT Pub. No. WO83/04143 PCT Pub. Date Nov. 24, 1983.An electrical plug and socket connection which is suitable for Diesel engine unit governors containing oil under pressure and which given the hard operation prevailing in motor vehicles is embodied as tight with respect to pressure, lubricating oil and splashing water and as vibration-proof. The electrical plug and socket connection has a first plug part (3), which is directed in a pressure-tight manner out of a housing (1) of the governor and in which plugs (11) are disposed, likewise in a pressure-tight manner. A second plug part (16) having plug sockets (29) for receiving the insertion sections (12) of the plugs (11), which sockets (29) are disposed in a sealed manner with respect to splashing water and soiling, has means (22, 34, 39, 40) for the sealed and strain-relieved reception of a cable (33), the stranded conductors (32) of which are secured on the plug sockets (29). The second plug part (16) is held on the first plug part (3) so firmly, in the inserted state, by a covering connection nut (42) that no relative movement is possible between the plug parts (3, 16) and thus between the plugs (11, 12) and the plug sockets (29).
