Brief description of the drawings
Fig. 1 is structure diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing with the specific embodiment term positions such as the invention will be further described, upper and lower, left and right mentioned in this article be layout taking each parts in Fig. 1 as benchmark, irrelevant with the as installed mode of native system;
The mechanical type that is applicable to petrol engine directly sprays oil supply system, comprises
Pump case 6, it is for being arranged on petrol engine, and pump case inner chamber 12 is shoe cream room, and pump case inner chamber is communicated with by oil pipe with the fuel tank of petrol engine;
Plunges pump body 2, it is arranged in pump case 6, the left end of plunges pump body 2 stretch out pump case 6 and with go out oil pump joint 1 and be connected, go out oil pump joint 1 and be connected to by oil pipe the fueling injection equipment 15 of combustion chamber of petrol engine;
Plunger pump core 7, it is the round bar being arranged in plunges pump body 2; On the sidewall of plunger pump core 7, form spiral chute 5, the inwall of spiral chute 5 and plunges pump body 2 coordinates formation oil supply, and oil supply is communicated with pump case inner chamber 11 and plunges pump body 12 inner chambers; On plunger pump core 7, be provided with the Returnning spring 8 that plunger pump core is moved to right, the right side of plunger pump core 7 coordinates with eccentric wheel impact block 10.The every rotation of eccentric wheel impact block 10 is just clashed into plunger pump core once in one week, make plunger pump core 7 move to left and the compression plunger pump housing 2 in fluid, fluid in plunges pump body 2 is subject to high pressure and sprays to the left with the state of atomization, and directly enters the fueling injection equipment of combustion chamber of petrol engine.
Preferably, the right-hand member of described plunger pump core 7 is provided with accelerator rod 9, and accelerator rod 9 coordinates with described eccentric wheel impact block 10.The design of accelerator rod 9 avoids eccentric wheel impact block 10 directly to clash into plunger pump core 7, after accelerator rod 9 and 10 wearing and tearing of eccentric wheel impact block, is all easy to change, and its maintenance cost is lower.
