As everyone knows, exhaust-gas turbocharger is as the key components and parts of supercharged engine, be arranged on the air outlet of enmgine exhaust, technical development is to today, the rotating speed of turbosupercharger is generally tens0000 turns and even 270,000 revs/min, if there is no good lubrication and cooling between the axle of High Rotation Speed and bearing, axle and bearing will inevitably ablations, inordinate wear and cause whole pressurized machine to lose efficacy, therefore lubricant oil enter and reflux must be unobstructed, traditional engine design setting type is, the upper end of oil return pipe of supercharger is connected to the return opening position on pressurized machine, lower end connects on the back oil road of cylinder block, or on return opening on oil sump, simultaneously the lower end of oil return pipe of supercharger is higher than the machine oil liquid level of engine sump tank, smooth and easy to ensure the oil return (by gravity) of pressurized machine, but for being subject to layout spatial constraints and the motor needing compact design, the drop of engine booster return tube upper and lower end is often less, cannot by the situation of the connection of lower end design more than engine oil level, one section of cavity can be formed in oil return pipe of supercharger between machine oil liquid level in pressurized machine lubricating oil return mouth and oil sump, its inner air cannot be got rid of, cause the oil return of pressurized machine gravity not smooth, occur that pressurized machine is altered oil and even damage and finally causes motor cannot meet the requirement of Performance And Reliability.
Therefore, be necessary to provide a kind of engine supercharger return line structure, can ensure that the oil return of pressurized machine gravity is smooth and easy, its structure is simple, compact, and make engine supercharger and relevant each component arrangement convenience, and assembling is simple, keeps in repair easy, finally reaches and meet engine reliability and the target effectively reducing complete machine manufacturing cost.
Summary of the invention
The object of this invention is to provide a kind of engine supercharger return line structure, can ensure that the oil return of pressurized machine gravity is smooth and easy, its structure is simple, compact, and make engine supercharger and relevant each component arrangement convenience, and assembling is simple, keep in repair easy, finally reach and meet engine reliability and the target effectively reducing complete machine manufacturing cost.
Engine supercharger return tube of the present invention, comprise main return tube and vent branch, one end of described main return tube is sealed with pressurizer oil mouth by one first flange and is communicated with, the other end is sealed with oil sump by one second flange and is communicated with, one end of described vent branch to be sealed with main return tube by the intercommunicating pore that is arranged at described main return tube center side wall and is communicated with, the other end by a three-flange and the back oil road of sloped cylinder seal be communicated with and port extend to form the fluid stopping pipeline section preventing the machine oil in cylinder back oil road from flowing to vent branch, described main return tube is provided with corrugated pipe segment, a bolt through-hole of described first flange is open wells.
Further, described fluid stopping pipeline section be straight length and the central axis upright of fluid stopping pipeline section in the central axis of sloped cylinder.
Further, described ventilation is propped up as zigzag thbe.
Further, described vent branch is provided with the joint of described main return tube and welds reinforcer.
Further, described welding reinforcer comprises the reinforcement cylinder that welds with described vent branch lower end mouth and the arc reinforced block with described main return tube sidewall weld, is provided with through hole and seals with described reinforcement cylinder bottom welding in the middle of described arc reinforced block.
Further, the length of described fluid stopping pipeline section is 15 ~ 20mm.
Beneficial effect of the present invention: oil return pipe of supercharger provided by the invention, by being communicated with arm, main oil gallery is communicated with the back oil road sealing of sloped cylinder, solve the problem that pressurizer oil restricts by the factor that drop is little, compact structure, make motor more reliable, the path of pipeline also can not be restricted, space can be abdicated for other component, add that a bolt through-hole of the bellows segment part that main return tube is provided with and connecting flange is designed to open type hole, make dismounting very easy, greatly reduce dismounting step to play, improve working efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation provided by the invention;
Fig. 2 is schematic diagram after assembling of the present invention.
Embodiment
Fig. 1 is structural representation provided by the invention, Fig. 2 is schematic diagram after assembling of the present invention, as shown in the figure, oil return pipe of supercharger in the present embodiment, comprise main return tube 1 and vent branch 2, one end of described main return tube 1 is sealed with pressurizer oil mouth by one first flange 11 and is communicated with, the other end is sealed with oil sump by one second flange 12 and is communicated with, one end of described vent branch 2 to be sealed with main return tube 1 by the intercommunicating pore that is arranged at described main return tube 1 center side wall and is communicated with, the other end by a three-flange 21 and the back oil road 31 of sloped cylinder 3 seal be communicated with and port extend to form the fluid stopping pipeline section 22 preventing the machine oil in cylinder back oil road from flowing to vent branch 2, main return tube 1 disconnects with the oil circuit of described back oil road by described fluid stopping pipeline section 22, ensure that the gas of described main reflow pipe can be got rid of simultaneously, pressurized machine is avoided to alter oil, the more important thing is that described main return tube 1 and back oil road are a closed pipeline, can effectively prevent foreign matter from entering return line, and machine oil can be avoided to evaporate reduce, reduce pollution to external world, increase the working life of machine oil, described main return tube 1 is provided with corrugated pipe segment 13, a bolt through-hole 111 of described first flange 11 is open wells, described open wells is a U-groove bevel, make dismounting very easy, greatly reduce dismounting step to play, improve working efficiency.
