Fig. 1 is for a kind of schematic structure of the speed regulator of instruction book cylinder diesel, and wherein, single cylinder diesel has a gear chamber cover 20.As shown in Figure 1, the speed regulator of single cylinder diesel comprises a speed governing axle 13, speed-regulating handle 12, oil mass fork plate 14, governor lever 11, enriching spring 16 and an oil-limiter 15.Speed governing axle 13 is rotatably installed on gear chamber cover 20, and speed-regulating handle 12 is fixedly connected with speed governing axle 13, and oil mass fork plate 14 is also fixedly connected with speed governing axle 13.Governor lever 11 is with speed governing axle 13 for being connected rotationally, and governor lever 11 can rotate around speed governing axle 13.
In the speed regulator of single cylinder diesel, one end of enriching spring 16 is connected in governor lever 11, and the other end of enriching spring 16 is fixed on gear chamber cover 20.Oil-limiter 15 is installed on gear chamber cover 20, and oil-limiter 15 can lean speed-regulating handle 12, to limit the slewing area of speed-regulating handle 12, and then the slewing area (referring to the respective description in Fig. 4) of restriction speed governing axle 13.
As shown in Figure 2,14 of oil mass fork plates are fixed on the radially outer edge place of speed governing axle 13, and oil mass fork plate 14 has the confined planes 142 and 144 that is positioned at governor lever 11 both sides, when rotating speed governing axle 13, oil mass fork plate 14 promotes governor lever 11 and rotates, play volume read-out and the effect that subtracts oil mass, and the slewing area of adjusting lever is limited in confined planes 142 and 144 determined scopes, so also just limited the minimum and maximum fuel delivery of single cylinder diesel.
As shown in Figure 2, in a kind of exemplary embodiment of speed regulator of single cylinder diesel, on a confined planes 144 in two confined planes 142 and 144 of oil mass fork plate 14, can also be provided with a position limit pin 141 that is arranged in oil mass fork plate.Position limit pin also can be arranged on another confined planes 142, or is equipped with position limit pin on two confined planes.Oil mass fork plate 14 and position limit pin 141 have limited the slewing area of governor lever 11 when speed governing axle 13 rotates.
As shown in Figures 2 and 3, in a kind of exemplary embodiment of speed regulator of single cylinder diesel, the radially outer edge place of speed governing axle 13 offers screw 132, and oil mass fork plate 14 is fixed on screw 132 by threaded fastener 134, thereby makes oil mass fork plate 14 be fixed on speed governing axle 13.Although in the exemplary embodiment showing at Fig. 2, oil mass fork plate 14 is fixed on speed governing axle 13 by a screw fastener 134, it will be appreciated by those skilled in the art that also can be with two or more than two screw fasteners 134.Oil mass fork plate 14 relies on screw thread to be fixedly connected on speed governing axle 13, can conveniently install.
As shown in Figure 3, in a kind of exemplary embodiment of speed regulator of single cylinder diesel, on speed-regulating handle 12, comprise a folding face 122 that is parallel to speed governing axle center 131, oil-limiter 15 can lean on folding face 122, with the slewing area of restriction speed-regulating handle 12, and then the slewing area of restriction speed governing axle 13.
Fig. 4 is for the working procedure of the speed regulator of instruction book cylinder diesel, during single cylinder diesel starting, in the scope that governor lever 11 can limit at oil mass fork plate 14 around speed governing axle 13, rotate, governor lever 11 is under the effect of enriching spring 16, make governor lever 11 in oil mass maximum position (position in figure shown in solid line), can make diesel engine start under the state that does not pull throttle control handle.After just starting of diesel engine, the diesel engine speed regulation sliding plate (not shown) that is arranged on governor lever divergent ends leans governor lever 11, makes governor lever 11 turn to position shown in dotted line.Operator pulls throttle control handle subsequently, thereby pull speed governing tension spring 30,30 of speed governing tension springs pull speed-regulating handle 12, be withdrawn into the position shown in solid line in figure, the rotation of speed-regulating handle 12 simultaneously drives speed governing axle 13 and oil mass fork plate 14 to rotate simultaneously, and drive governor lever 11 to turn to position shown in dot and dash line in figure to the direction of Injection Pump oil mass increase, now enriching spring 16 is in extended state.
Due to the active force of the speed governing sliding plate active force much larger than enriching spring 16, so can ignore the active force of enriching spring 16 after starting.When operator carries out shut-down operation, speed governing tension spring 30 is return, speed-regulating handle 12, speed governing axle 13 and oil mass fork plate 14 are rotated simultaneously, and drive the direction that governor lever 11 reduces to Injection Pump oil mass to rotate, reach cut-out position and can make Injection Pump fuel cut-off, thereby diesel engine is quit work.After diesel engine quits work completely, enriching spring 16 is pulled to governor lever 11 position of Injection Pump oil mass maximum again.
The speed regulator that adopts single cylinder diesel of the present utility model, pulls throttle control handle without operator during diesel engine starting, and enriching spring can be drawn to governor lever separately oil mass maximum position, to facilitate starting; And after starting, due to the effect of the speed governing sliding plate effect much larger than enriching spring, thus fuel delivery can reduce immediately, thereby reduced starting smoke intensity.
