In oil suction chamber, deposit oil, extrudes oil and produces oil pressure in extrusion chamber; In extrusion chamber during oil-feed, oil suction chamber communicates with extrusion chamber; In extrusion chamber during oil extraction, oil suction chamber is sealed with the internal taper hole in ferrite core piston by ball sealer or sealing cone and is disconnected the oil inlet passage entering extrusion chamber.

Described efficient oilling machine environmental protection and energy saving pump extracts in the process of oil in the oil tank of gas station, and controlling does not have return spring in the one-way check valve of oil inlet passage and oil discharge passage; When oil suction chamber oil-feed, the suction of the up generation of ferrite core piston is opened the sealing of the sealing neck of sealed cap and pump oilcan lower end and is opened the passage of oil-feed, is arranged on sealing surface on the sealing neck in ferrite core piston automatic decline return and the passage of closing the oil-feed entered in extrusion chamber under the effect of self gravitation and seals; When extrusion chamber oil-feed, be arranged on that ball sealer on the internal taper hole of outlet valve or sealing cone utilize that the gravity of self makes ball sealer or the sealing automatic decline return of cone and the fuel-displaced passage of closing on outlet valve seals, the descending and up passage then opening the oil-feed entered in extrusion chamber of sealed cap that makes to produce oil suction chamber on sealing neck that pressure promotion is arranged in ferrite core piston of ferrite core piston; When extrusion chamber is fuel-displaced, under the effect going out oil pressure, promote ball sealer on the internal taper hole of outlet valve or sealing cone up and open the fuel-displaced passage of outlet valve, the sealed cap be arranged on the sealing neck in ferrite core piston utilizes the gravity of self to make sealed cap decline return and the passage of closing the oil-feed in ferrite core piston seals automatically.

In order to ensure that efficient oilling machine environmental protection and energy saving pump can normally work, the oil gun be connected with insulated electric conductor is adopted to oppress connection and the cut-out that circuit switch carrys out the connecting circuit of controlling magnetic field controller.

In order to ensure that buoyancy shell can keep shape and be not easy distortion, in the inner chamber of buoyancy shell, manufacture the skeleton having support.

In order to ensure that oil can normally enter in oil inlet hole, the center of gravity of buoyancy shell is manufactured on the position near oil inlet hole.

In order to enable oil enter in pump oilcan, the oil inlet hole swimming in the buoyancy shell on pasta must slip into the following oil pump of pasta and can normally work.

There is no impurity and moisture to ensure to enter in the oil in oil pump, when the bottom of oil inlet hole close to the bottom of the oil tank of gas station or oil depot, adopting foot rest to support buoyancy shell and the bottom of the oil tank of oil inlet hole and gas station or the bottom of oil depot are maintained a certain distance.

In order to enable the oil in the oil suction chamber in ferrite core piston driving pump oilcan enter in extrusion chamber, the electromagnetic field adopting lower magnet to produce moves down as pulling ferrite core piston the power oil in oil suction chamber being clamp-oned extrusion chamber.

During use, be put in the oil in the oil tank of gas station or in oil depot by efficient oilling machine environmental protection and energy saving pump, oil inlet hole gos deep in oil, the upper part emersion pasta of buoyancy shell.After picking up nozzle, the power-on circuit that field controller connected by circuit switch oppressed by the oil gun be connected with insulated electric conductor, and the power-on circuit that field controller connects circulation connection upper magnet and lower magnet generates an electromagnetic field; When upper magnet generates an electromagnetic field, the attraction force of electromagnetic field pulls ferrite core piston to move up, when ferrite core piston starts up, be arranged on sealed cap on the sealing neck in ferrite core piston descending and close the oil inlet passage that oil enters extrusion chamber under the effect of the gravity of self; When ferrite core piston is up, ferrite core piston up and make the oil in extrusion chamber create pressure, have the oil of pressure from the endoporus of the sealed end of outlet valve lower end enter into internal taper hole in outlet valve promote ball sealer or sealing cone up and open the sealing channel of outlet valve, make the oil in extrusion chamber through outlet valve, after connector of oil pipes of oil, enter into oil-piping through nozzle again and refuel to automobile or oil holder; Ferrite core piston is when up, ferrite core piston also makes to create pull of vacuum in oil suction chamber, it is up and the annular sealing surface of the sealing neck upper end of pump oilcan lower end is separated with the inner sealing surface of sealed cap that pull of vacuum inhales motive sealing cap, in the oil suction chamber below the oily ferrite core piston entered from the oil-through hole of oil inlet hole through sealed cap in pump oilcan.

Ferrite core piston is up when moving into place, and field controller connects the power-on circuit of lower magnet after disconnecting the power-on circuit of upper magnet, and the electromagnetic field of upper magnet disappears, and the electromagnetic field that lower magnet produces pulls ferrite core piston descending; When ferrite core piston starts descending, be arranged on the descending return and close the oil inlet passage entering oil suction chamber under the effect of self gravitation of the sealed cap on the sealing neck of lower end in pump oilcan, ball sealer in outlet valve or sealing are bored descending return under the effect of the gravity of self and seal the inner conical surface of outlet valve, have cut off the oil discharge passage of extrusion chamber; Ferrite core piston is when descending, ferrite core piston promotes the oil that enters in oil suction chamber and makes oil produce internal pressure, the upper end of the sealing neck having the oil of pressure to enter in ferrite core piston from the oil through in ferrite core piston is upwards washed the sealing of the inner sealing surface of annular sealing surface and sealed cap open and continues up after sealed cap is shifted, and enters in extrusion chamber after the oil-through hole on sealed cap after the oil through in restriction plug again.

Ferrite core piston is when the gravitation of the electromagnetic field that lower magnet produces pulls descending putting in place, be arranged on sealed cap on the sealing neck in ferrite core piston descending and the annular sealing surface of sealing neck upper end is shut and makes oil not return oil suction chamber under the effect of the gravity of self, now, the power-on circuit that field controller connects again magnet again generates an electromagnetic field and pulls ferrite core piston up; The connection of circulation like this and cut-out circuit, the electromagnetic field that upper magnet is produced pulls ferrite core piston electromagnetic field that is up and that allow lower magnet produce to pull ferrite core piston descending, constantly oil pump is gone out and is transported in oil-piping and refuels to automobile or oil holder through nozzle.When needing to stop refueling, that unclamps nozzle goes out after oil switch closes the oil outlet of nozzle, and nozzle is placed on oil gun compressing circuit switch, and disconnect the power-on circuit of field controller, gasoline pump quits work.In the process extracting oil, buoyancy shell can automatically raise with the rising of pasta or reduction or decline.
