Definitions

  • flyweight governor The most important requirement a flyweight governor has to meet is that it should have a large working capacity. Where a flyweight governor is intended to be used in conjunction with an internal combustion engine of the fuel injection type, such a governor is in addition required to occupy as little space as possible, and the governor should be of simple and rugged construction. It is of prime importance that the friction between the moving parts of a flyweight governor should be kept at a minimum so as not to impair the working capacity and the sensitivity of the governor. In the manufacture of fiyweight governors intended for use in conjunction with fuel injection type internal combustion engines, i.e. in cases in which mass production procedures are applied, it is more over important to reduce production and assembling costs to a minimum.
  • flyweight governor including a plurality of flyweight mounted for pivotal motion radially of the governor shaft, which flyweights co-operate with a springloaded sleeve axially slidably supported by the governor shaft in such a manner as to cause any pivotal motion of the flyweights to produce an axial displacement of said sleeve, to meet the aforementioned requirements which are partly contradictory. It is another object of the invention to provide a flyweight governor of the general type mentioned whose construction permits the working capacity of the governor to be easily matched with the controlling force the governor is required to produce.
  • a flyweight governor of the type named a pot-like casing carried by the governor shaft and provided, in its cylindrical portion, with radial grooves adapted to receive and laterally guide a plurality of plate-like flyweights, the said casing being further provided with an annular groove receiving an annular wire serving as a pivot for the said flyweights.
  • the said casing of the flyweight governor is mounted for free ro tation and axial displacement in relation to the governor shaft, there being interposed between the casing and the governor shaft 2.
  • device adapted to dampen torsional vibrations the said device connecting the casing to the governor shaft for rotation therewith.
  • the easing of the flyweight governor is enclosed in a cup-like member formed of sheet metal, the cylindrical wall of the cup-like member forming an abutment limiting the outward pivotal motion of the flyweights.
  • FIG. 1 is an axial sectional view, partly in elevation, of one embodiment of a flyweight governor according to the invention
  • FIG. 2 is an end elevational view of the flyweight governor of FIG. 1;
  • FIG. 3 is an axial sectional view, partly in elevation, of a modified embodiment of the invention.
  • FIG. 4 is an end elevational view of the flyweight governor of FIG. 3.
  • FIG. 5 is a fragmentary cross-section along the line V-V of FIG. 4.
  • FIG. 1 the governor shaft 1 carrying a potlike casing 2 which is freely rotatable and axially displaceable in relation to the governor shaft.
  • A. damper disc 3 which, together with a sheet-metal cup 4 surrounding the casing 2, is secured to a sleeve 5 for rotation therewith, the said sleeve being press-fitted to governor shaft 1 and being secured by known means to shaft 1 for rotation therewith, connects the governor shaft 1 to the housing 2 so that these members rotate in unison.
  • a cup spring 6 bearing on the hub portion of easing 2 as well as on a circular clip 7 mounted in an annular groove provided in shaft 1 urges casing 2 against damper disc 3.
  • a plurality of flyweights 8 Disposed within casing 2 are a plurality of flyweights 8, the outer ends of the flyweights being engaged in radial slots 9 formed in the cylindrical portion of the pot-shaped casing 2.
  • a ring 19 made of spring wire forms a pivot for the flyweights 8.
  • the ring 10 is disposed in an annular groove 11 formed in casing 2.
  • a plurality of clips 12 made of spring wire retain the ring 10 in the groove 11.
  • the said clips 12 are bent to U-shape; they are disposed in axially extending grooves 13 formed in the peri hery of easing 2, one leg of each clip being clamped in position between casing 2 and the sheet-metal cup 4 surrounding the casing.
  • FIGS. 3 to 5 show a modified arrangement for locking and retaining ring 10 in position.
  • the groove 21 receiving ring 10 is undercut rather than being formed to have a semicircular cross-section as is the case with the aforedescribed annular groove 11.
  • the groove 21 affords axial support for the ring 10, such axial support being afforded by the clips 12 in the embodiment shown in FIGS. 1 and 2.
  • a screw 22 which is engaged in a threaded hole provided in a sector-shaped web 23 of casing 24, the construction of casing 24 in all other respects corresponding to that of the easing 2 described earlier.
  • the screw 22 has a tapered head 25 engaging the beveled ends of ring 10 so as to spread apart the ends of the ring in a tangential direction, the result of this arrangement being that ring 10 is fully engaged with groove 21 and is securely held in position.
  • flyweights 8 in the grooves 9 of casing 2 and the large number of grooves 0 available makes it possible, for example, to employ but -a small number of flyweights to obtain a correspondingly small working capacity of the flyweight governor of the invention, or to dispose a flyweight in each of the grooves for the purpose of obtaining the maximum working capacity of the governor, it thus being possible to adjust the working capacity in an almost stepless manner.
  • the flyweights 8 each carry a projection 14, the projections 14 of all flyweights used being engaged in an annular groove 15 formed in the control sleeve 16 disposed co-axially with the governor shaft 1.
  • the control sleeve 16 is guided by a sleeve member 17 supported for free rotation and axial displacement in relation to governor shaft 1.
  • the control sleeve 16 Upon the flyweights 8 being pivoted outwardly as a result of an increase in the speed of governor shaft 1, the control sleeve 16 will be displaced axially, producing a corresponding axial displacement of sleeve member 17.
  • Mounted within the sleeve member 17 is one race of a ball thrust bearing 18, the other race of bearing 18 being a press fit on a cylindrical portion of a thrust member 19.
  • Thrust member 19 is axially spring-loaded by known means (not shown).
  • a spring ring 20 located in an annular groove formed in sleeve member 17 serves to locate thrust bearing 18 in an axial direction
  • a fiyweight governor comprising a plurality of flyweights mounted for pivotal motion radially of a governor shaft, said fiyweights being in engagement with a spring loaded sleeve adapted to be axially displaced in relation to said governor shaft in such a manner that any pivotal motion of the flyweights will produce a displacement of said sleeve, a pot-shaped casing on said governor shaft, said casing including a cylindrical portion formed with radial slots adapted to receive and laterally guide a plurality of plate-like fiyweights, said casing being provided with an annular groove receiving a ring formed of wire and serving as a pivot for said fiyweights, said wire formed ring being held in position by a plurality of clips equidistantly spaced along the circumference of the ring, said clips being of U-shape and made of spring wire, said clips straddling the periphery of said casing to retain said ring in said annular groove formed in said casing.
