Abstract
A fuel injection pump is proposed having a rotating distributor, which is axially adjusted by an electromagnetic final control element counter to the force of a restoring spring. The force of the restoring spring is transmitted via an intermediate ring onto a collar of an armature serving as a coupling element, with the armature being provided with an axial recess into which a fitting part of the core of the electromagnet can plunge when magnetic force is applied.
Claims11
A fuel injection pump having a housing comprising, a rotary distributor for determining injection duration and for injection timing, said rotary distributor positioned in a bore in said housing, an associated electromagnetic final control element and a control unit therefor, said electromagnetic final control element arranged to adjust said distributor counter to a restoring force, a transducer for detecting the axial position of said distributor, said transducer being connected to said electric control unit, means firmly joined to one end of said distributor, said means having an outer circumference including a collar, an intermediate ring supported on said collar, spring means urging said intermediate ring against said collar and means carried by said intermediate ring, said last named means adapted to transmit signals to said transducer.
