Definitions

  • the present invention relates to a centrifugal speed governor, especially for prime movers, according to which the flyweights are adapted through the intervention of a springloaded adjusting sleeve and a linkage to act upon a member controlling the supply of fuel, preferably the control rod of an injection pump, while in addition to the control springs proper at the adjusting members, an additional spring acts upon a lever linked to the adjusting members which lever is through a delaying element yieldably joumalled in the housing.
  • the additional spring is frequently used for imparting upon the load-speed characteristic of the governor the inclination suitable for the operation.
  • a stiffer additional spring increases the so-called degree of non-uniformity of the governor (i.e. the difference between the idling speed and the speed of the prime mover under load) to a greater extent than does a sofl: additional spring.
  • degree of non-uniformity i.e. with a flat line of characteristic of the governor
  • the governor has the tendency to carry out a pendulum movement. If for reasons of operation it is necessary to have a smaller degree of non-uniformity, damping elements are provided in a manner known per se. In this way a non-periodic cushioning or damping can be realized.
  • an additional spring is interposed between the governor and the damping element.
  • This additional spring is so dimensioned that within its range of expansion during operation, the characteristic of the governor is directed upwardly to such an extent that the danger of obtaining a pendulum movement does not exist any longer.
  • the influence of the additional spring disappears when the damping member has adjusted itself to the new point of operation.
  • a governor which is more responsive and faster in its reaction reacts to a cyclic non-uniformity of the drive with a high frequency movement of the control rod.
  • the governor may itself become an amplifier for amplifying the oscillations when the non-uniformity at the drive is caused by the fundamental frequency of a system adapted to oscillate in the arrangement.
  • it is necessary to design the governor in such a way that it is slow to react to the adjustment of the governor. This, however, can bev effected only to such an extent as a stability reserve is available and the entire system will not have the tendency to carry out a rotary pendulum movement.
  • a centrifugal speedgovernor for prime movers in which the fly-weights act through a spring-loaded adjusting sleeve and a linkage upon a measuring element for the fuel supply, preferably the control rod of an injection pump, while in addition to the control springs proper the adjusting elements are also acted upon by an additional spring through a lever linked to the adjusting elements, is, in conformity with the present invention, characterized in that said lever in addition to an additional spring is operatively connected to a holding member of magnetizable material, which holding member is axially movably arranged in a magnetic field.
  • the magnetizable holding member For the function of the governor it is advantageous to design the magnetizable holding member with a length approximating the length of the coil while the adjusting holding means and housing parts consist of non-magnetizable material. As a result thereof, the influence of the change in the position of the holding member at the start of the movement will be rather high. Thisinfluence can be further increased or im proved by employing as holding member a rod magnet or an electromagnet. In the last mentioned instance, the change in the holding force of the holding member may be effected by increasing the magnetic induction of the electromagnet.
  • fly-weights 1 designed in the form of an angle lever are joumalled on the fly-weight carrier 2.
  • This carrier 2 is fixedly mounted on a driven control shaft 4 which is driven in conformity with the gears 3.
  • the fly-weights l are operatively connected through an anti-friction bearing 5 with the adjusting sleeve 6 and the control lever 7.
  • the adjusting sleeve 6 is acted upon by control spring 8 in a manner known per se.
  • the entire system is housed in a housing 9 which is partially filled with a lubricant.
  • An additional spring 10 acts upon adjusting sleeve 6 through the intervention of a two-arm lever 11 linked to the intermediate members 12, 13.
  • the other arm of the two-arm lever 11 is by means of a rod 22 pivotably connected to a piston which latter is guided with slide fit in a cylinder 15 at a low point of the housing 9 below the oil level. From the cylinder bottom, a connecting conduit 17 leads into the oil reservoir 18.
  • the cross-section of the passage 21 is, for obtaining the desired choke effect, adapted to be varied, for instance, by means of an adjusting element, such as a screw 19.
  • the outer channel or conduit mouth 20 is located as low as possible whereas the inner passage mouth 21 is located as high as possible.
  • the additional spring 10 is engaged by an adjusting screw 23 with transverse pins 24.
  • the windings of the additional spring 10 and the thread of the adjusting screw 23 have the same pitch. In this way it will be assured that the starting position of the two-arm lever l 1 during the adjustment of the additional spring 10 will not be changed.
  • the adjusting screw 23 is held in a threaded bore 25 and is secured in its respective position by means of a counter nut 26.
  • the desired speed adjustment may be obtained by a corresponding adjustment of a speed adjusting lever 27.
  • the lever 11 is through a rod 28 pivotably connected to a holding member 29 which is axially displaceably mounted in a housing part 30 and is surrounded by a coil 31 which is fixedly connected to the housing and is adapted to be passed through by a current.
  • the magnitude of the current of the coil is adjustable by standard devices not illustrated.
  • the holding member 29 comprises three parts of which the intermediate part 34 consists of magnetizable material whereas the end parts 32 and 33 consist of non-magnetizable material. It is likewise advantageous to make the housing part 20 as well as the rod 28 of non-magnetizable material.
  • the intermediate part 34 of the holding member 29 is held in its intermediate position. In this position, the holding forces are strongest whereas they greatly decrease when the holding member 29 is shifted.
  • the magnitude of the holding force may be adjusted by changing the intensity of the current in coil 31.
  • a centrifugal speed governor with resilient return mechanism so that with change of load there is previous centrifugal speed again attained after a short time without any diversion arising as a result of changed load condition, especially for internal combustion machine prime movers having predetermined speed maintained independent of loading condition at a time which includes: a governor housing, control shaft means for driving connection with a machine to be controlled, fly-weight means contained in said governor housing and keyed to said control shaft means for rotation therewith and adapted in response to an increasing speed of said control shaft means to move in one direction, spring loaded actuating means operatively connected to said fly-weight means for urging said fly-weight means to move in a direction opposite to said one direction, linkage means pivotally connected to said actuating means for controlling the fuel supply to the machine to be controlled, lever means pivotally connected to said actuating means, adjustable auxiliary spring means effective length of which is adjustable independently of said governor housing and operatively connected to said lever means for adjusting the same, holding means operatively connected to said lever means to oppose movement of
  • a fly-weight centrifugal speed governor according to claim 1, which includes control linkage means operatively connected to said actuating means.
  • a fly-weight centrifugal speed governor which includes electric coil means for creating said magnetic field, said magnetizable member having a length approximately equaling the length of said electric coil means, those parts of said governor which are adjacent said holding means being of a non-magnetizable material.
  • a fly-weight centrifugal speed governor according to claim 1, in which said holding means is formed by a permanent bar magnet.
