Definitions

  • This invention relates to a centrifugal governor for the r.p.m. control of internal combustion engines operating on injected fuel.
  • the centrifugal governor is of the type wherein the governor member (such as a governor rod) displaces a fuel quantity control member of a fuel injection pump through an intermediate lever which is supported pivotally on a pin integral with an actuating member which serves for the arbitrary adjustment of said fuel quantity control member.
  • the centrifugal governor is further of the type wherein the traveling path of the fuel quantity control member in the direction of fuel increase is limited, on the one hand, by an abutment which is secured to the governor housing and adjustable in the direction of the pump axis and which determines the fuel quantities for full load, and, on the other hand, by a follower nose secured to said intennediate lever.
  • said governor member during change of r.p.m. shifts the location of its joint with the intermediate lever, said follower nose is displaced in alignment with the longitudinal axis of the intermediate lever and transversally relative to the direction of adjustment of the abutment.
  • a force accumulator which is loaded as soon and as long as the intermediate lever urges the fuel quantity control member to move beyond said abutment.
  • the abutment secured to the housing is displaceable in the axial direction of the pump and may be immobilized in any desired position.
  • the abutment is provided with a curved contour (adapter curve) which corresponds to or very closely approximates the r.p.m.-dependent course of fuel quantity requirements'necessary for a smokefree combustion or for particular operating conditions.
  • curve is used in its broad sense, thus including contours of linear configuration.
  • the fuel quantity control rod of the associated fuel injection pump is displaced, during r.p.m. change, as a function of said adapter curve.
  • actuating member which is jointed with an operator lever
  • a force accumulator is loaded and the governor member is displaced.
  • the fuel quantities delivered by the fuel injection pump for full load are, dependent upon the course of the adapter curve, increased or decreased in a predetermined manner.
  • centrifugal governor of the aforenoted type such as disclosed, for example, in German Pat. No. l,0l0,32l the curved contour of the abutment secured to the housing is provided with an additional portion which determines the maximum fuel quantities required for the starting of the engine.
  • the adjustable abutment is provided with a pivotable abutment plate having a contour constituting an adapter curve. Said plate may be immobilized in any set position.
  • the intermediate lever there is mounted a follower nose integral with a rocker and settable into a position from which, prior to the starting of the engine and during the motion of the actuating member into the full load position, it may be swung under the abutment plate.
  • the follower nose will engage the abutment plate in ranges beyond the starting r.p.m.
  • FIG. I is a longitudinal sectional view of a preferred embodiment of the invention.
  • FIG. 2 is a partial sectional view along line II-II of FIG. I;
  • FIG. 3 is a partial sectional view along line III-III of FIG. I.
  • FIG. '1 to the drive shaft of a schematically indicated fuel injection pump 1 of an internal combustion engine (not shown), there is keyed a conventional centrifugal governor generally indicated at II, the governor rod 12 of which is connected with an intermediate lever 14 by means of a pin I3.
  • the latter is affixed laterally to a slide member 15 and is jointedly connected with a lever 16 which, in turn, is pivotally secured to the governor housing 18 by means ofa pin 17.
  • the movements of the governor rod 12 are transmitted to a fuel quantity control rod 22 of the fuel injection pump I through an intermediate lever 14 pivotally held on a pin 19 of an actuating member 20, 25 and through an intermediate link 21.
  • the actuating member 20 is keyed to a shaft 23 rotatably held in housing 18. To shaft 23 there is also afi'lxed, outside housing 18, an operator lever 24. It is thus seen that the actuating lever 20 and the operator lever 24 form a bell crank turnable as a unit.
  • the pin 19 afi'ixed to a jointed link 25 of the actuating lever 20 projects with one end into a guiding slot 26 of the intermediate lever 14 and engages with its other end a curved slot 27, formed in a plate 29 pivotable about a pin 28 secured to the housing 18.
  • the plate 29 is. in its initial position, urged by a spring 30 into contact with an abutment 31 secured to the housing 18.
  • the plate 29 and the spring 30 serve as a force accumulator.
  • a rocker 33 provided with a follower nose 32.
  • the rocker 33 is further provided with an adjusting screw 34 secured by means of a U-shaped spring plate.
  • the screw 34 urged by a spring 35 into contact with the intermediate lever 14, determines the angular position of the follower nose 32 with respect to said lever I4.
  • a device which is formed of a bolt-shaped terminus 38 of the intermediate link 21, a spring 39 tensioned between a collar 36 and a snap ring 40 (both secured to the bolt-shaped terminus 38), a nut 41 and a counter nut 42 (both mounted on a threaded portion 37 of tenninus 38) and a jointed member 43.
  • the latter is held in the intermediate lever 14 by means of two lateral pins 44, which also carry the rocker 33.
  • the jointed member 43 is urged against a frontal face of the nut 41 secured by the counter nut 42.
  • the other end of the spring 39 engages the snap ring 40.
  • the maximum adjusting range is determined by the difference between the height of the collar 36 and the depth of a depression 45 in the jointed member 43. It is an advantage of the aforedescribed mechanism for fine adjustment that during the exact adjustment or readjustment for full load fuel quantities, the already set, rpm-dependent fuel delivery is not altered. Such alteration would, however, occur should the hereinafter described abutment itself be displaced along the fuel quantity control member 22.
  • the housing 18 has an opening normally closed by a lid 46.
  • abutment 48 for determining the full load fuel quantities delivered by the fuel injection pump.
  • the abutment 48 extends into the housing 18 with a leverlike abutment plate 50 provided with a contour edge 49.
  • the abutment 48 is built as follows: An abutment housing 52 secured to the face 47 by means of screws 51 is provided with guide faces 53 for a bearing block 54 and may be displaced by means of an ad justing screw 55 in the axial direction of the fuel injection pump 1.
  • the abutment housing 52 may be immobilized in its set position by means of a clamping plate 56 and a screw 57.
  • the bearing block 54 carries on an integral arm 58 extending into the housing 18, a pin 59 on which the abutment plate 50 is mounted in such a manner that it is adapted to pivot through an angle of about :l
  • the angular position of the abutment plate 50 is determined by means of a setting screw 61 and a spring'62.
  • the setting screw 61 is secured to the bearing block 54 by means of a nut 60.
  • a stop 63 secured to the driven side of the pump in alignment with the axis of the fuel quantity control rod 22.
  • the operator lever 24 is moved in the direction of arrow lV into the full load position, whereby the fuel quantity control rod 22 is shifted into the starting position by the actuating member 20, 25, the intermediate lever 14 and the intermediate link 21.
  • the intermediate lever 14 pivots about pin 13
  • the follower nose 32 is freely swung under the curve 49 of the abutment plate 50.
  • the starting position is limited by the abutting engagement of the fuel quantity control rod 22 with the stop 63.
  • the setting of the rpm. at which the follower nose 32 may just move past the abutment plate 50 is performed by moving the rocker 33 from its position of rest by means of the adjusting screw 34.
  • the fuel quantities are limited by the curved abutment edge 49, the inclination of which may be varied by the setting screw 61. It is noted that by inclination there is meant here the slope of the contour edge 49 in an imaginary fixed coordinate system.
  • the governor rod 12 of the centrifugal governor 1 I moves to the left (FIG. 1) in a known manner and carries with it the slide member 15.
  • the pin 13, guided by the lever 16, executes a stroke in addition to its longitudinal motion, and the intermediate lever 14 is pivoted about the momentary fulcrum 19 in such a manner that the follower nose 32 of the rocker 33 is brought into a position close to the off position shown in the drawing.
  • the fuel quantity control rod 22, by means of the intermediate link 21, is drawn into a corresponding position and, as a result, the fuel quantities injected into the engine are decreased.
  • the follower nose 32 despite its stroke motion caused by levers l6 and 14, may swing back under the abutment plate 50 during high r.p.m.'s by virtue of the spring-loaded rocker 33.
  • a decrease in the fuel quantities injected into the engine causes a drop in the r.p.m. and, as a result, the slide member 15 moves towards the right into a position corresponding to the full load position of the operator lever 24. in this position of the slide member 15, the follower nose 32 abuts against the curved edge 49. This position of the follower nose 32 is shown at 32 in a dash-dot line in FIG. 1. in this instance the pin 13 assumes a position shown at 13'.
  • the pin 13 shifts from its position 13' in the direction of its position shown in solid lines and the follower nose 32 slides on the curved edge (adapter curve) 49 and, for a lower r.p.m., assumes a position indicated, for example, at 32".
  • the adapter curve described by the follower nose 32 as it traces the edge 49 depends upon the curve slope which, as explained earlier, is variable by the setting screw 61. in position 32 the force accumulator 29, 30 is loaded: the plate 29 moves away from the abutment 31 against the force of the spring 30 into the dash-dotted position at 29".
  • the engine is stopped by setting the operator lever 24 in the off position as shown in the drawing.
  • the fuel injection pump may be shut off in a known manner by cutoff means (not shown) moving the fuel quantity control rod 22 against the force of the spring 30 independent of the position of the operator lever 24.
