The remote siphon hole 3a is communicated with the remote end of the oil tank through an oil pipe, and the remote injection hole 3b is communicated with an oil outlet hole of a pump core of the fuel pump, so that fuel entering the remote injection hole 3b has certain pressure.
In order to realize the communication between the holes, the far-end oil outlet hole 3c and the far-end injection hole 3b are communicated through a long hole 3d arranged in the far-end injection block 3, and the far-end oil outlet hole 3c and the far-end siphon hole 3a are communicated through a connecting hole 3e horizontally arranged. The far-end siphon hole 3a and the far-end injection hole 3b are correspondingly provided with a far-end siphon joint 4 and a far-end injection joint 5. In this embodiment, the lower end of the remote siphon connector 4 is correspondingly inserted into and welded with the upper end of the remote siphon hole 3a, the lower end of the remote injection connector 5 is correspondingly inserted into and welded with the upper end of the remote injection hole 3b, and the remote injection block 3 is inserted into and welded with the remote oil outlet extending hole 2a of the remote injection fixing block 2 through the lower end of the remote oil outlet hole 3 c.
Simultaneously for convenient processing, draw oil outlet 3c and distal end to draw the hole 3b setting to draw the one end of penetrating piece 3 at the distal end, and the one end that connecting hole 3e is close to distal end siphon hole 3a outwards wears out distal end and draws and penetrate piece 3, the one end of wearing out at connecting hole 3e is equipped with leak protection end cap 6, because elongated hole directly sets up the inconvenient processing in the distal end draws the piece 3, consequently draw and be provided with between hole 3b and draw at distal end oil outlet 3c and distal end and draw case 7, set up elongated hole 3d in drawing case 7.
In order to prevent the elongated hole from being blocked in the use process, a filter screen 8 is arranged in the far-end injection joint 5, and the diameter of a filter hole of the filter screen 8 is not more than that of the elongated hole 3 d.
When the distal end injection hole 3b inserts the fuel that has pressure, the fuel can enter into distal end oil outlet 3c behind the elongated hole under the effect of gravity, because the fuel pressure behind the elongated hole can increase and appear the siphon to take the fuel of oil tank distal end to enter into distal end oil outlet 3c along oil pipe, distal end siphon hole 3a, connecting hole in, the last is gone out oil along the distal end and is extended hole 2a and enter into the oil bath together.
In this embodiment, install pressure regulator 9 in the mounting hole 1a that sets up outside oil sump 1 lower extreme, and through advancing oil pipe 10 intercommunication between pressure regulator 9 and oil sump 1 are inside, be provided with horizontally fuel sprayer 11 at the oil outlet end of pressure regulator 9, be provided with injection nozzle 12 at the other end of fuel sprayer 11. The injection nozzle 12 comprises an injection large section 12a and an injection small section 12b, the oil nozzle 11 is inserted into the injection large section 12a of the injection nozzle 12, the oil nozzle 11 and the injection nozzle 12 are all arranged in a near-end injection hole 1b at the bottom of the oil pool 1, the above is the prior art, and the description is omitted.
For preventing because of drawing the diameter of penetrating the segment little, and the thrust reverser when leading to the fuel to pass through is too big, radially be provided with on penetrating the segment 12b with draw penetrating segment intercommunication and vertical ascending pressure release hole 12c, be provided with the pressure release via hole 13 with oil bath 1 intercommunication simultaneously directly over pressure release hole 12 c. In order to realize that the oil pressure in the small section 12b is ejected to exceed a set value and then is decompressed, a decompression component is arranged in the decompression through hole 2 c.
Specifically, the pressure relief via hole 13 includes a pressure relief cavity 13a at an upper end and a pressure relief oil inlet hole 13b at a lower end, and a diameter of the pressure relief cavity 13a is larger than a diameter of the pressure relief oil inlet hole 13 b. The pressure relief assembly comprises a pressure relief valve core 14, the lower end of the pressure relief valve core 14 is abutted against the steps of the pressure relief cavity 13a and the pressure relief oil inlet hole 13b, a pressure relief spring 15 located in the pressure relief cavity 13a is arranged at the upper end of the pressure relief valve core 14, and the pressure relief spring 15 is used for adjusting the set value of oil pressure during pressure relief. In order to fix the pressure relief spring, a pressure relief plug 16 for abutting against the upper end of the pressure relief spring 15 is fixedly arranged at the upper end of the pressure relief cavity 13a, in order to realize the pressure relief of the fuel, a pressure relief outlet 13c is radially arranged at the position, close to the upper end, of the pressure relief cavity 13a, and the pressure relief outlet 13c is communicated with the inside of the oil pool.
When the oil pressure in the small injection segment does not exceed a set value, no action can be generated, when the oil pressure in the small injection segment exceeds the set value, the elastic force of a pressure relief spring can be overcome to jack up the pressure relief valve core upwards, then fuel oil enters the pressure relief cavity, and finally flows back into the oil pool from the pressure relief outlet, so that the pressure relief of the small injection segment is realized.
In order to facilitate the installation of the pressure relief spring, a lower protrusion 16a for sleeving the pressure relief spring 15 is arranged at the lower end of the pressure relief plug 16, and an upper protrusion 14a for sleeving the pressure relief spring 15 is arranged at the upper end of the pressure relief valve core 14.
In order to prevent the concentration of static electricity in the voltage regulator, a static terminal 10 which is positioned outside the oil pool 1 and used for leading out the static electricity in the voltage regulator 9 is arranged on the joint of the voltage regulator 9.
