Working principle of the present utility model and working procedure are:

When gas entered in the cavity of piston cylinder by valve joint, valve spare, under the pressure of gas, piston slided in the cavity of piston cylinder, selector valve slides on the rear wall of piston cylinder and in the back cavity of piston cylinder rear end simultaneously.Because the slip of piston in the piston cylinder cavity, just promoting piston rod slides in the cross-drilled hole in the oil circuit cover word of falling T hole, owing to the slip of piston rod, just the grease in the vertical core in oil duct spare T font hole is pushed through in the groove of the inwall of core retainer plate and oil nozzle core and makes grease slide to the inner chamber of oil connection, slide to oil pipe and oil gun in succession, when opening the oil gun switch, grease just is injected among the lubricated part of machine; Meanwhile, because selector valve is on the rear wall of piston cylinder and the slip in the back cavity of piston cylinder rear end, selector valve just impels the rear wall choke-out of piston cylinder the slip of piston; Its first action is finished.After its first action is finished, its piston just slides to the right-hand member of piston cylinder cavity, and the aperture in the commutation hole in the piston cylinder cavity just is in the left side of piston, just because the aperture in commutation hole is in the left side of piston, just make and enter the gas that has certain pressure in the piston cylinder cavity by valve joint and valve spare, directly lead to the inboard set groove of end cap from the aperture in commutation hole, and the ear end face of selector valve produced pressure, force selector valve in the back cavity of piston cylinder, to slide to the right in reciprocal mode, just because the to the right slip of selector valve in the piston cylinder back cavity, selector valve has just been opened the natural hole identical with the external world set on the piston cylinder back cavity, gas with pressure is emitted from natural hole, thereby played the effect that reduces the piston cylinder pressure, because the reduction of piston cylinder internal air pressure, under the effect of piston spring, all reset to reset condition and make baffle plate drive piston rod and promote parts such as piston, piston is returned to original position again, the aperture in commutation hole is in the position on piston right side again; In finishing the process of This move, owing to piston rod returning from oil circuit cover cross-drilled hole pulled out and the oil nozzle spring makes the oil nozzle core that core retainer plate is shut to the roof pressure effect of oil nozzle core, make the L hole of the common formation of part cross-drilled hole institute of the vertical core of vertical core, oil circuit cover of oil duct spare and right section form negative pressure, be exactly because this negative pressure, make the lubricant oil in the oil drum just glide automatically, thereby get ready for next time lubricant oil is extruded by oil duct spare; Its second action is finished.Above-mentioned first action and second reciprocation cycle of moving realize the filling to engine oil.In the filling process of realizing engine oil, lubricant oil be placed on oil drum go up in the bucket and also on lubricant oil, have the leather cup spring arranged between leather cup, leather cup and the bung, effect just because of the leather cup spring, thereby formed leather cup to lubricant oil lasting extruding from start to finish, oil channel hole at the bottom of making lubricant oil by the oil drum bucket enters oil duct spare and each later parts, thereby makes smooth and easy the carrying out of operation of filling lubricant oil.When oil drum need increase when filling out lubricant oil, as long as will exit stifled opening, just air enters into the bucket end of oil drum by center tube, to remove lubricant oil cohering to leather cup.Owing to the length of oil pipe in the utility model can be set as required, so the utility model can be to the annotate operation of lubricant oil of machine in blocks and long-range machine, it uses extremely convenient and quick.

Since adopted technological scheme provided by the utility model, since above described to working principle of the present utility model and working procedure, thus make the utility model compare with existing known technology, obtained following beneficial effect:

1,, thereby obtained the well-off beneficial effect of lubricant oil because the utility model is provided with oil drum.

2, owing to the length of oil pipe in the utility model can be set as required, can be thereby obtained to the annotate beneficial effect of lubricant oil operation of machine in blocks and long-range machine.

3,, thereby obtained lubricated oil supplying beneficial effect continuously because the utility model is provided with leather cup, leather cup spring.

4, connect female, parts such as gas is stifled, venting is stifled, center tube because the utility model is provided with, thereby can remove the beneficial effect that lubricant oil coheres leather cup when having obtained to increase lubricant oil.

5, be provided with pulley, draw handle owing to the utility model, thereby obtained the beneficial effect of conveniently moving.

6, since drawing of establishing of the utility model on be equipped with hook, thereby but obtained hook when not using and deposited the beneficial effect of oil pipe.

7,, thereby obtained to use the beneficial effect that pneumatic principle is extruded lubricant oil because the utility model is provided with parts such as air pump, valve spare, valve joint, piston cylinder, piston, piston rod, piston spring, oil duct spare.

8,, thereby obtained to make piston to drive the beneficial effect that parts such as piston rod reset because the utility model is provided with parts such as natural hole, selector valve, piston spring.

9,, thereby obtained by each parts annotate lubricant oil operation and extremely convenient and beneficial effect efficiently because the 7th, 8 of being provided with of the utility model is described.

10, because above-mentioned each bar of the present utility model is described, thereby obtained to develop " pneumatic grease injector " new product, solve deficiency, defective and the drawback of existing known technology, use pneumatic and piston principle, make to simple to operate, the saving of labor of machine filling lubricant oil, save time, speed is fast, can carry out the continuity operation, change the mode of operation that falls behind, and is beneficial effect such as wide popularization and application in to the operation of machine filling lubricant oil.

11, since design science of the present utility model rationally, simple and ingenious structure, conveniently make operation, effect stability is reliable, thereby the beneficial effect of low, an easy to use and sharp popularization that obtained to be easy to be made.
