Definitions

  • ABSTRACT In the fuel injection pump there is provided an adjusting member for the delivery per revolution controlled by a regulator.
  • This device comprises retractable stop means adapted to limit the stroke of the adjusting member, so that the delivery per revolution does not exceed a full load value. Control means for the retraction of said stop means are provided.
  • the invention relates to a device intended to limit the delivery per revolution of a fuel injection pump for an internal combustion engine, in which pump there is provided a regulating member for the delivery per revolution controlled by a regulator which is driven by the engine supplied by the pump.
  • the delivery per revolution takes values essentially variable according to the conditions of operations of the engine. These various values of the delivery per revolution are adjusted by the regulator. Generally, on the starting of the engine, by an electric starter for example, it is necessary for the delivery per revolution to be high in order to facilitate the starting of the engine. This high flow rate on starting is denoted by the term supercharge delivery.
  • the delivery per revolution of the pump is less than the supercharge delivery, the maximum value assigned to this delivery by the regulator being denoted by the term full load delivery.
  • This delivery corresponds to the optimal value enabling the creation of a maximum engine torque without the production of smoke due to unburnt fuel.
  • the regulator controls a rapid movement of the regulating member for the delivery perrevolution of the pump and, by.reason of the inertial forces which are applied to this regulating member, as well as to the moveable parts of the regulator, the value of the full load delivery can be exceeded.
  • a device intended for limiting the delivery per revolution of a fuel injection pump for an internal combustion engine in which pump there is provided a regulating member for the delivery per revolution controlled by a regulator which is driven by the engine supplied by the pump, is characterised by the fact that it comprises, on one hand, re-
  • tractable stop means adapted to limit the stroke of said regulating member so that the delivery per revolution does not exceed a full load value and, on the other hand, control means for the retraction of the abovesaid stop means adapted to come into action, especially on the starting of the engine, to enable the delivery per revolution to take values greater than those at full load.
  • the retraction control means are constituted by an electromagnet comprising a movable core adapted to cooperate, through a linking rod, with the retractable stop means.
  • the coming into action of the retraction control means may be servo'coupled either to the operation of the electric starter, or to the temperature of a fluid of the engine which is heated on the operation of this engine, for example the cooling water or the lubricating oil of the engine.
  • the regulating member for the delivery per revolution is constituted by a rack adapted to slide in its longitudinal direction, according to a first embodiment the plane of the arm, the pivoting axle of said arm being borne by a casing shielding the injection pump.
  • This pivoting axle of the arm is advantageously mounted eccentrically on a screw, so that, by rotation of the latter, an adjustment may be effected, in the direction of the axis of the rack, of the position of the arm.
  • the retractable stop means comprise a rod, substantially parallel to the rack and pivoted, especially by a spherical ball-joint, on an adjusting screw borne by the casing and parallel to the rack; this rod traverses, preferably, an aperture provided in a plate borne by the connecting rod of the electro-magnet of the control means, said aperture being elongated in the direction of the axis of the'rod; a transverse plate, connected to the rack, is provided to cooperate with the abovesaid rod when the latter is not retracted.

  • the middle plane of this arm is parallel to the axis of the rod 2 and to the axis of the electromagnet 14. Preferably, this plane is vertical as shown in the drawings.
  • the arm 24 is pivoted, at its end 24a, on an axle 25 perpendicular to the middle plane of the arm.
  • the axle 25 is mounted in eccentric manner on a screw 26, with a head having a blind hole, borne by the casing E and'blocked on the latter by a counter-nut 27 (FIG. 2).
  • the eccentricity between the axle 25 and the screw 26 is indicated by E in FIG. 2.
  • the arm 24 is comprised, transversely, between the rack 2 and the neighbouring wall of the casing E.
  • the concave portion of the arm 24 comprises a zone 28 of which the surface, when this arm occupies the position shown in FIG. 1, is substantially vertical.
  • the zone 28 is adapted to cooperate with the finger 29 borne by the intermediate part 4 and at right angles to the axis of the rack 2 and to the middle plane of the arm, as clearly seen in FIG. 3.
  • the zone 28 constitutes the portion of the concavity of the arm which is distant from the axle 25.
  • the intermediate portion 24c of the arm 24 is parallel to the rod 2 and traversed vertically by a housing 30 of which the planar cross-section, as visible in FIG. 3, is elongated in the direction of the rack 2.

  • the end 24b of the arm 24, spaced from the pivoting axle 25, comprises a fork 33 seen clearly in FIG. 3, extending the arm in the direction of the intermediate portion 24c.

  • a stop lever 34 is keyed on a rotary axle 35 of which an arm 36, accessible from the outside of the casing E, enables rotation in anticlockwise direction, when looking at FIG. 3, to actuate the stopping of the engine by annulation of the delivery of the pump.
  • This lever 34 cooperates with a pin 37 borne by the upper portion of the linking part 4.
  • the electromagnet 14 is subjected to voltage, so that the core 15 passes from the low position shown in FIG. 1, to its high position.

  • the rack 2 can then be moved freely in the direction of increasing the delivery per revolution. Due to the fact that the engine is in the course of starting, the regulator 3 controls a displacement of the rack 2 until the position corresponding to the supercharge flow-rate, which is greater than the normal full load delivery rate. As a result the finger 29 is brought close to the finger 22 and it is passed below the end 24b of the arm 24.
