Engine supercharger return tube assembly of the present utility model, 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 vent branch is 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.
The beneficial effects of the utility model: the diesel engine pressurizer oil pipe assembly that the utility model provides, 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
