Next consult Figure 19, it illustrates the sectional view of a preferred embodiment of jerk fuel injection pump 400 in oil-way system of the present invention.Jerk fuel injection pump 400 comprises upper pump casing 411, lower pump body 417, filler opening 413, oil outlet 412, outlet valve 415, outlet valve valve seat 410 and plunger 420.Right side cavity 421 and left side cavity 422 is provided with in upper pump casing 411; Upper pump casing 411 is linked together by joint 416 and lower pump body 417; Joint 416 is provided with seal ring with upper pump casing 411 and lower pump body 417 joint.Be equipped with outlet valve 415 in right side cavity 421 and left side cavity 422, outlet valve 415 is resisted against in outlet valve valve seat 410 by oil outlet valve spring 414; Right side cavity 421 communicates with filler opening 413, and left side cavity 422 communicates with oil outlet 412.Described lower pump body 417 is the inner housing having cavity, and plunger 420 is placed in the cavity of lower pump body 417; Oil pump spring 418 is installed in the cavity of lower pump body 417, and is resisted against the top of the cavity of lower pump body 417 by plunger 420; The lower end of described plunger 420 is provided with roller 419.
Plunger 420 is made up of plunger bushing (mark) and plug core (mark), plunger bushing is installed on lower pump body 417 also fixing, lower pump body 417 and upper pump casing 411 are sealed connected together by joint 416, and plug core moves up and down under the effect at intake cam 216.When plunger 400 is descending, filler opening 413 is opened, and the lubricant oil in oil sump 317 enters in the cavity 421 of right side, intake cam 216 turns over several angle, plug core is up, and now plunger bushing, plug core top and outlet valve form confined space, and plunger continues up, the lubricating oil pressure of plunger body raises, until after being greater than outlet valve 415 cracking pressure, extruding from oil outlet 412, enter oil road 311 and spray, then intake cam 216 continues to rotate, and enters next circulation.
When motor enter from air-inlet cavity 12 pressurized air start working time, bent axle on crankshaft system 200 rotates counterclockwise, the intake cam 216 that bent axle is connected by key also rotates along with rotating counterclockwise of bent axle 211, when bent axle turns over 75 degree, lower pump body 417 upper roller 419 of jerk fuel injection pump 400 slides into the basic circle disc of intake cam 216, owing to being provided with oil pump spring 418 in plunger 420, therefore move downward at the elastic force lower plunger 420 of oil pump spring 419, air in upper pump casing 411 is drawn out of, upper pump casing 411 inside produces pressure difference, and then the outlet valve 415 under filler opening 413 presses to the inner chamber of outlet valve valve seat 410, lubricant oil in oil sump 317 flows through filler opening 413 by oil input channel 310 from sucking-off in oil sump 317 and enters in the right side cavity 421 of upper pump casing 411 after fine cleaner 316 removal of impurities.
After intake cam 216 rotates 240 degree, protruding disc on intake cam 216 and roller 419 inconsistent, plunger 420 is moved upward, and oil pump spring 418 is compressed, and the lubricant oil in right side cavity 421 presses to rapidly in the left side cavity 422 of upper pump casing 411 by the extruding force of oil pump spring 418.The outlet valve 415 that the lubricant oil entered in the cavity 422 of left side backs down under oil outlet 412 is opened, and the lubricant oil in left side cavity 422 sprays from oil outlet 412 discharge currents through oil road 311 rapidly.
Lubricant oil in oil road 311 is divided into two-way footpath to circulate: a road is upwards oil duct 312, and another road is crankshaft lubrication oil duct 314.The upwards valve end of oil duct 312 first in lubricating engine control system 100, the lubricant oil come from valve end subordinate enters exhaust rocker arm 115, flows to exhaust tappet 114, air inlet tappet 133, intake cam 216, exhaust cam 215 and air inlet successively subsequently control bearing 130, gas exhaust inspecting bearing 110 etc. along exhaust rocker arm.
The oil channel hole of lubricant oil in crankshaft lubrication oil duct 314 in bent axle 211 enters connecting rod lubrication oil duct 313 pairs of piston rods (mark) and lubricates, and the lubricant oil flowing through piston rod lubricates piston rod and bent axle 211 surface of contact simultaneously; The piston cavity that the lubricant oil got off from piston rod enters piston 18 is lubricated piston cavity.
After each component lubrication that lubricant oil in oil road 310 flows through upwards oil duct 312 and crankshaft lubrication oil duct 314 pairs of motors completes, final lubricant oil falls in engine body shell 13, then is got back in oil sump by the return tube 315 of machine shell 13 bottom.Engine reciprocations rotate time, oil-way system to each parts of motor according to above-mentioned greasing circulating lubrication.
Although disclose in detail the present invention with reference to accompanying drawing, it should be understood that these descriptions are only exemplary, be not used for limiting application of the present invention.Protection scope of the present invention by appended claims, and can be included in the various modification made for the present invention of pin when not departing from scope and spirit, remodeling and equivalents.
