Definitions

  • ABSTRACT A centrifugal r.p.m. governor for fuel injected internal combustion engines.
  • the governor includes a fuel quantity control rod of a fuel injection pump, an intermediate lever, a connecting structure connecting the control rod and the intermediate lever, an adaptor sleeve connected to the intermediate lever, centrifugal weights which are connected to the adaptor sleeve, an operating lever having a pin which engages the intermediate lever, an adaptor mechanism, an energy accumulator and a stop.
  • the adaptor mechanism has a spring as does the energy accumulator, which are tensed as soon as and for so long as the intermediate lever tends to move the control rod beyond a position determined by the adaptor mechanism.
  • the connecting structure has mounted thereto a first set screw a path-limiting structure and a counter stop.
  • the counter stop includes a member which engages the stop within the limits defined by the path-limiting structure. The movement of the counter stop member is in response to the movement of the operating lever, intermediate lever and adaptor sleeve.
  • the centrifugal r.p.m. governor of the type under consideration has a control member whose position changes in dependence on engine r.p.m. and in response to the centrifugal force generated by fly weights of the governor.
  • the control member actuates an intermediate lever which in turn acts on a control rod of the injection pump.
  • the intermediate lever is carried on a stud belonging to a pivotable setting member whose purpose is the arbitrary movement of the control rod.
  • the governor further includes an adaptor mechanism which limits the path of the control rod in the direction of increasing fuel quantity.
  • the mechanism consists substantially of an adaptor spring, a stop located in the governor housing and adjustable in the direction of the control rod and also of a counter stop disposed on a connecting member lying between the intermediate lever and the control rod. Further there is provided a spring of an energy accumulator which is tensioned along with the adaptor spring as soon and for so long as the intermediate lever tends to move the control rod beyond the position determined by the adaptor mechanism.
  • the adaptor spring is a part of the adjustable stop mounted in the govemor housing so that the entire stop mechanism is moved in the direction of motion of the control rod for achieving the adaptor path and this is done by an appropriate mounting of the stop and an appropriately adjusted stroke of the bearing member in which the stop is carried.
  • This adaptor mechanism is extremely difficult to adjust, is subject to frictional losses and requires a relatively large space which extends beyond the outer dimensions of the governor and this space requirement leads to difficulties in installation in the cramped assembly conditions in motor vehicles.
  • the adaptor spring is supported by the connecting member on the one hand and by the counter stop on the other hand, where the counter stop is part of a rocker arm which is pivotable about an axis located in the connecting member and within an angular sector which is limited by a first set screw and by a path-limiter on the connecting member.
  • the rocker arm In the vicinity of its pivotal axis, the rocker arm is equipped with a stop member which extends beyond the axis and is perpendicular with respect to the axis and which cooperates with a stop projection of the adjustable stop mechanism attached to the governor housing.
  • the counter stop which is embodied as a rocker arm has only negligibly small friction compared with the amount of friction of the longitudinal moving parts of the known adaptor system.
  • the adaptor elements which have been displaced into the interior of the governor make possible a diminution of the contruetional space requirements of the governor and in addition the setting of the full-load position of the control rod and of the adaptor path can be made by spatially separated adjustment elements, independently of one another and in a continuous manner.
  • a further improvement as to the setting capability of the present invention is given in that the pretension of the adaptor spring can be adjusted by a second set screw disposed in the connecting member and embodied as a spring support bearing.
  • the present invention is further embodied advantageously in that the two screws are disposed in the connecting member substantially parallel to one another and can be adjusted from the same side of the governor. This significantly simplifies the setting capability of the governor.
  • a further advantageous embodiment of the present invention provides that the stop in the rocker arm is the cylindrical stop stud of a further set screw which is screwed through the pivotal axis of the rocker arm and that the stop mounted in the governor housing is equipped with a pivotable stop lever of a known type provided with a stop projection.
  • the stop lever can be pivoted out of the path of the stop stud by a control lever, actuated by the adaptor sleeve, coupled to the stop lever and mounted in the governor housing.
  • the stop lever In other positions of the adaptor sleeve, however, the stop lever extends into the path of the stop stud.
  • the advantage of this disposition is that the additional set screw, together with the parts which serve for controlling an automatic surplus quantity permits, without exchange of governor elements and in a simplified fashion, the adjustment of the r.p.m. at which the pivotable stop lever arrives in the position which serves to limit the full-load position of the control rod.
  • the further set screw be disposed approximately parallel to the first or second set screw and that it may be adjusted from the same side of the governor which simplifies the setting of the governor in an advantageous manner.
  • FIG. I is a longitudinal sectional view of a first preferred exemplary embodiment of the centrifugal r.p.m. governor according to the present invention.
  • FIG. 2 is a longitudinal sectional view of a second preferred exemplary embodiment of the centrifugal r.p.m. governor according to the present invention.
  • FIG. 3 is a simplified representation of the essential constructional elements of the second exemplary embodiment in the position which they occupy at the beginning of the adaptation process.
  • FIG. 4 shows the elements of FIG. 3 in the position that they occupy at the termination of the adaptation process.
  • the embodiment of the centrifugal r.p.m. regulator or governor shown in FIG. I includes a housing 10 and a drive shaft I I extending from an injection pump (not shown) for internal combustion engines.
  • the housing carries a known centrifugal governor 12 which includes fly-weights 13 that extend, in a known manner, due to the effect of centrifugal force and against the force of regulator springs 14, from the axis of the drive shaft 11.
  • the regulatory motions of the governor are transmitted via an angled lever 15 to a governor or adaptor sleeve 16 serving as control member.
  • the adaptor sleeve 16 carries a sliding ring 17 equipped with a bearing stud 18 to which is coupled an intermediate lever 19 embodied as a twin armed lever whose one lever arm 19a is connected with the adaptor sleeve 16 and whose other lever arm 19b is pivotably connected to a connecting member 21 embodied as a double rail and ultimately to a control rod 22 of the injection pump.
  • the intermediate lever 19 is provided with a known slot and pin guide linkage 23 whose pivotal point is a pin 24 gliding in a slot and where the pin is part of a guide lever 25 which, in turn, is in fixed rotational connection with an opcrtaing lever 27 serving as a setting member.
  • a lever pin 26 is affixed to the governor housing 10.
  • the housing 10 also includes a support bore 28 whose axis is oriented in the same direction as the axis of the control rod 22 and which carries a stop 31 which in turn forms part of an adaptor mechanism 29.
  • a cylindrical portion 32 of the stop 31 within the support bore 28 is secured against rotation by a pin 33 engaging a groove 34.
  • the portion 32 is, however, adjustable in the longitudinal direction by a set screw 35 held in its installed condition by a lock nut 36.
  • a stop 31 and the other elements which serve to set and mount it in a separate housing within the governor housing 10.
  • Connected to the cylindrical portion 32 of the stop 31 is an abutment arm 37 which extends into the governor housing and whose extreme end is provided with a stop projection 38 bent at right angles to the plane of the figure.
  • the double rail 21 has two mutually parallel and identical rails 41 of which only one is shown. A second section through the apparatus is superfluous since the double rail 21 is completely symmetric and is shown sectioned along its longitudinal axis.
  • the rails 41 are connected to one another by two cross ties 42 and 43.
  • the rocker arm 44 serving as a counter stop and including a pivot pin 45.
  • the rocker arm 44 is a counter stop for the stop 31 and includes a centerpiece 46 which carries the pivot pin 45 and through which a bolt 47 may be pushed that extends at right angles to the rotational axis of the rocker arm 44 and which serves as a stop element by extending through the centerpiece 46 so that during longitudinal motions of the control rod 22, the bolt 47 makes contact with the stop projection 38 of the stop 31.
  • the rocker arm 44 has two lever arms 44a and 44b extending in the longitudinal direction of the double rail 21.
  • One of the lever arms 44a carries a support bearing 48 for an adaptor spring 49 while the other lever arm 44h moves between the path limiting cross tie 42 and a collar 51 of a first set screw 52. in the position in which it is shown. the rocker arm 44 attaches to the path limiting cross tie 42 due to the force of the adaptor spring 49.
  • the prctension P,- in the adaptor spring 49 can be adjusted by a second set screw 53 embodied as a spring support bearing.
  • the two set screws 52 and 53 are screwed into the two cross ties 42 and 43. respectively.
  • the governor housing 10 has an opening 56 closed by a cover 57.
  • the adaptor sleeve 16 contains a energy accumulator 58 consisting of a sliding bolt 59 and a spring 61.
  • This energy accumulator 58 serves as a drag link and is required in the centrifugal r.p.m. governor according to the invention because it operates as a variable r.p.m. regulator.
  • the spring 61 is matched with the spring 49 of the adaptor mechanism 29 for the control of the adaptation process.
  • the sliding bolt 59 is connected with the angled levers 15 by means of a lateral pin 62 and the distance between this lateral pin 62 and the bearing stud 18 is constant as long as the force exerted on the adaptor sleeve 16 does not exceed the pretension of the spring 61.
  • the operating lever 27 and hence the pin 24 is rotated in a clockwise sense in order to obtain a greater fuel quantity, and when, consequently, the intermediate lever 19 attempts to move beyond the position determined by the projection 38 of stop 31, then the spring 16 is compressed and pretensed in a known manner.
  • the relative motion between the transverse pin 62 and the adaptor sleeve 16 is made possible by longitudinal slits 63 in the wall of the adaptor sleeve 16 and the longitudinal motions of the transverse pin 62 are made possible by corresponding slits 64 in a travelling member 65 of the centrifugal governor 12.
  • FIG. 2 illustrates a second exemplary embodiment of the present invention and it differs from that in FIG. 1 only by the additional of new constructional elements which serve to make possible providing an automatic excess starting fuel quantity.
  • Corresponding parts of the two exemplary embodiments are provided with the same reference numberals. All movable elements of both exemplary embodiments are shown in their quiescent position (stop position).
  • the energy accumulator 58 has s sliding bolt 71 which is longer than the sliding bolt 59 of FIG.
  • the end of the control lever 75 facing away from the adaptor sleeve 16 carries a pin 79 engaging an enlongated hole 81 of a stop lever 82 and controlling its pivotal position.
  • the stop lever 82 has a stop projection 83 and is pivotably connected with a cylindrical portion 84 of a stop 85 carried within the governor housing 10.
  • the mounting and the adjustability of the cylindrical portion 84 are the same as in the case of the cylindrical portion 32 of FIG. 1.
  • the rocker arm 44 located within the double rail 21 differs from that in FIG. 1 in that the place of the bolt 47 of FIG. 1 is taken by the cylindrical stud 86 of a third set screw 87 and serving as a stop.
  • This third set screw 87 is screwed through the pivotal axis of rocker arm 44 formed by the centerpiece 46 and is secured in its installed position by a lock nut 88.
  • the third set screw 87 is positioned approximately parallel to the other two set screws 52 and 53.
  • FIGS. 3 and 4 serve for the illustration of the method of operation of the apparatus according to the present invention and they show the second exemplary embodiment of FIG. 2 in a simplified representation. Whereas in FIG. 2 all movable parts were shown during the stop position of the governor and when the operating lever was in its stop position, the operating lever 27 as shown in FIGS. 3 and 4 is in its full-load position or in that operational position which determines the maximum r.p.m. of the engine.
  • FIG. 3 the remaining movable parts of the governor are shown in the position which they assume at that r.p.m. at which the adaptor process is to begin.
  • the control lever 75 abuts at its stop 78 and fly weights 13 have assumed a position where, via angled lever 15, they have moved the transverse pin 62 and hence, the sliding bolt 59 into locations such that the head 72 of the sliding bolt 59 is no longer in contact with the transmitter pin 74 of the control lever 75.
  • the abutment stud 86 of rocker arm 44 abuts against the stop projection 83 of the stop lever 82 belonging to the stop mechanism 85 and the adaptor spring 49 is pretensed.
  • the lever arm 44b of the rocker arm 44 abuts against the collar 51 of the first set screw 52 and spring 61 of the energy accumulator 58 within the adaptor sleeve 16 is pretensed in such a way that a clearance a has been established between the head 72 and the adaptor sleeve 16.
  • FIG. 4 represents the positions of the governor parts which are assumed at the termination of the adaptor motions.
  • the fly weights 13 have assumed a position further removed from the drive shaft 11 due to the increased r.p.m. and the sliding bolt 59 of the energy accumulator 58 has been correspondingly moved to the right in the drawing and the head 72 of this sliding bolt 59 has again made contact with the governor sleeve 16.
  • the spring 61 of the energy accumulator 58 and the adaptor spring 49 within the double rail 21 are relaxed and the arm 44b of the rocker arm 44 now attaches to the path limiting cross tie 42 of the double rail 21.
  • the stop projection 83 of the stop lever 82 has resumed its original position but the rocking motion of the rocker arm 44 and the correspondingly changed position of the abutment stud 86 of the third set screw 87 have caused the control arm 22 to be moved from the position shown in FIG. 3 by an amount X in the direction of the arrow.
  • the two simplified representations of FIGS. 3 and 4 are also valid for the adaptation control in the first exemplary embodiment because in the fullload position. the stop lever 82 has not changed and remains in the same position as the abutment arm 37 provided with an abutment projection 38 belonging to the stop mechanism 31.
  • the fly weights 13 move outwardly and, via angle levers 15, move the adaptor sleeve 16 so that the intermediate lever 19 moves the connecting rail 21 and hence the control rod 22 in the direction of stop.
  • the head 72 of the sliding bolt 71 moves from the position shown to the right in the figure.
  • the control lever 75 is pivoted counterclockwise by the force of pressure spring 76 and thus moves the abutment lever 82 also in the counterclockwise sense so that the abutment projec tion 83 is moved upwardly toward the abutment stud 86.
  • the abutment projection 83 moves up against the abutment stud 86 until the regulatory motions of the fly weights 13, the adaptor sleeve 16 and the intermediate lever 19 have moved it so far to the left that it no longer makes contact with the abutment projection 83.
  • the abutment lever 82 can reach the position shown in FIG. 3 and when the r.p.m. decreases further, the abutment stud 86 moves up against the abutment projection 83 and at the lowest adaptation r.p.m., the rocker arm is moved into the position shown in FIG. 3 against the force of the spring 49. If the r.p.m. increases further. the adaptor sleeve 16, intermediate lever 19, the double rail 21 and the rocker arm 44 assume the positions shown in FIG. 4 where, as already described, the control rod 22 is moved in the stop direction through an adaptation distance .r.
  • the governor stops the fuel supply and the control rod 22 arrives at the stop position shown in FIGS. I and 2.
  • the first set screw 52 sets the adaptation paths .i' which the governor is to provide.
  • the second set screw 53 and. in the exemplary embodiment shown in FIG. 24, the third set screw 87 sets the point at which the abutment projection 83 moves out of engagement with the abutmcnt stud 86 and thus the control rod 22 can move beyong the full load position into the starting position.
  • This last mentioned setting is very important because, during the normal operation of the engine. an automatic delivery of of the starting excess quantity of fuel must not take place.
  • the position of the abutment projection 38 in FIG. 1 or of the abutment projection 83 in FIGS. 2-4 determines the position of control rod 22 governing the pre-load fuel quantity and can be changed by rotation of the set screw 35 (see FIG. 1.),
