Embodiment
In order to the technical characteristics to invention, object and effect have understanding clearly, now contrast accompanying drawing and the specific embodiment of the present invention is described, accompanying drawing only understands the present invention for helping, not the practical structures of representative products and actual proportions, and label identical in the various figures represents identical part.
In this article, " schematically " expression " serves as example, example or explanation ", not should by being described to any diagram of " schematically " in this article, mode of execution is interpreted as a kind of preferred or have more the technological scheme of advantage.In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".
As shown in Figure 1, single cylinder diesel has a gear chamber cover 20.As illustrated in fig. 1 and 2, the speed regulator of single cylinder diesel comprises a speed governing axle 13, speed-regulating handle 12, governor lever 11, bounding means 14, oil-limiter 15 and an enriching spring 16, speed governing axle 13 is rotatably installed on gear chamber cover 20, and speed-regulating handle 12 is fixedly connected on speed governing axle 13.Governor lever 11 is connected to speed governing axle 13 rotationally, governor lever 11 has a supporting portion 112 can rotated around speed governing axle, supporting portion 112 offers a spacing hole 114, speed governing axle 13 offer a fixed hole 134 in the radial direction, bounding means 14 is fixed in fixed hole 134, and is arranged in spacing hole 114 movingly.One end of enriching spring 16 is connected to governor lever 11, and the other end 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 governing axle.
Fig. 3 is for illustration of the working procedure of the speed regulator of single cylinder diesel.During diesel engine starting, governor lever 11 can rotate in bounding means 14 and spacing hole 114 limited range around speed governing axle 13, governor lever 11 is under the effect of enriching spring 16, turn to the position in figure shown in solid line, now the fuel delivery of diesel engine is maximum, and operator does not pull throttle control handle to make diesel engine starting.After diesel engine just starts, speed governing tension spring 30 pulls speed-regulating handle 12, the rotation of speed-regulating handle 12 drives speed governing axle 13 and bounding means 14 to rotate simultaneously, and after bounding means 14 leans spacing hole right-hand member edge, governor lever overallly together along with the rotation of speed governing axle 13 can rotate (position in figure shown in solid line) to oil mass augment direction.
Owing to being arranged on the active force of active force much larger than enriching spring 16 of the diesel engine speed regulation sliding plate (not shown) of governor lever divergent ends, so the active force of enriching spring 16 can be ignored after starting.When operator is stopped, pull throttle control handle, speed governing tension spring 30 is return, make speed-regulating handle 12, speed governing axle 13 rotates together with bounding means 14, bounding means 14 lean spacing hole 114 left end edge after governor lever 11 can along with the rotation of speed governing axle 13 together to fuel delivery reduce direction rotate (position in figure shown in dotted line), reach cut-out position and can make Injection Pump fuel cut-off, thus diesel engine is quit work.After diesel engine stops completely, governor lever 11 is pulled to the maximum position of Injection Pump oil mass by enriching spring 16 again.
In exemplary embodiment as shown in Figure 3, the fixed hole 134 of speed regulator is pin-and-hole, and bounding means 14 is position limit pin.For realizing the object of fixing, fixed hole 134 also can be tapped hole, and bounding means 14 can be combined on the bolt of this tapped hole.
Fig. 4 schematically illustrates the shape of various spacing hole applicatory in speed regulator, situation when wherein dotted line represents that bounding means is in diverse location in spacing hole, as shown in the figure, spacing hole can be such as the circular hole as shown in figure (a), or the elongated hole in speed governing axis 132 direction along speed governing axle 13 of figure shown in (b), or the elongated hole of the circumference along speed governing axle 13 of figure shown in (c), or as figure (d) be depicted as governor lever bottom slot, rely on through speed governing axle bounding means to limit governor lever slewing area and move axially.Circular hole is easy to process, and the elongated hole along axis then can be avoided affecting slewing area because of moving axially of governor lever.Wherein scheme (a) and figure (b) needs to rely on speed governing axle bottom support to limit moving axially of governor lever, elongated hole circumferentially not only the bounding means that also can rely on easy to process to limit moving axially of governor lever.But figure (d) form relies on bounding means to limit moving axially of governor lever with figure (c).
Adopt the speed regulator of single cylinder diesel of the present invention, pull throttle control handle during diesel engine starting without the need to operator, governor lever can be drawn to oil mass maximum position separately by enriching spring, to facilitate starting; And after starting, because the effect of speed governing sliding plate is much larger than the effect of enriching spring, so fuel delivery can reduce immediately, thus reduce starting smoke intensity.In addition, have employed bounding means and make it to fix with speed governing axle, and speed governing axle can be made in the motion at spacing hole institute limited range, thus drive governor lever to rotate, to increase or to reduce fuel delivery, the structure of this speed regulator is simple, and installation and maintenance are convenient.
Be to be understood that, although this specification describes according to each embodiment, but not each embodiment only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for possible embodiments of the present invention; they are also not used to limit the scope of the invention; allly do not depart from the skill of the present invention equivalent embodiments done of spirit or change; as the combination of feature, segmentation or repetition, all should be included within protection scope of the present invention.
