Patent number: 4320733Abstract: A fuel injection pumping apparatus of the rotary distributor type has an angularly adjustable cam ring to which is connected an arm. The arm is engaged by a surface on a linearly movable actuating member the position of which varies in accordance with the speed of the associated engine. The arm is also engaged with a cam connected to an operator adjustable member which is also coupled to an arrangement for controlling the amount of fuel supplied by the apparatus. The arrangement is such that movement of the operator controlled member effects an immediate adjustment of the timing of fuel delivery, the timing also varying as a result of speed variation.Type: GrantFiled: July 3, 1980Date of Patent: March 23, 1982Assignee: Lucas Industries LimitedInventor: Dorian F.

Patent number: 4318379Abstract: A control apparatus for a fuel injection pump of a diesel combustion engine is proposed, in which the fuel delivery adjustment element of the injection pump is moved to its zero adjustment position when the engine cuts off, is held in this position (roll-start lock), and can reach its start-position only in accordance with standard starting procedure. The control apparatus includes a hydraulically actuated correcting element, that can be placed under fuel delivery pump pressure by means of a directional control valve for displacing the fuel delivery adjustment element into its zero adjustment position. The correcting element is locked by a slide lock, likewise controlled by delivery pump pressure. The slide lock is brought into its blocking position when the delivery pump pressure drops sufficiently, and retracted only when the driver actuates the directional control valve and the delivery pump pressure increases when the engine starts.Type: GrantFiled: October 2, 1979Date of Patent: March 9, 1982Assignee: Robert Bosch GmbHInventor: Peter Knorreck

Patent number: 4313409Abstract: A centrifugal rpm governor, intended in particular for Diesel vehicle engines, is proposed, by means of which the supply quantity adjustment member of the injection pump is held in the stop position after the engine has been turned off, in order to prevent unauthorized and unintended starting of the engine. The governor is provided with a shut-off lever held in its operational position by a tension spring and by which lever the supply quantity adjustment member of the injection pump is displaceable into its stop position. The tension spring is embodied as a holding spring and so disposed that the shut-off lever both in its operation position and its shut-off position is drawn into the pertinent terminal position and held there. To this end, the force of the holding spring is greater than the force of a deviation spring attached to the control linkage.Type: GrantFiled: October 24, 1979Date of Patent: February 2, 1982Assignee: Nippondenso Co.
