Abstract
The utility model provides an oil return pipe of an engine oil-gas separator. The oil return pipe of the oil-gas separator is arranged between the engine oil-gas separator and an engine oil level gauge and directly communicates the oil-gas separator with an oil pipe of the oil level gauge, and the separated oil is delivered back to an engine cylinder body through the oil pipe of the oil level gauge. With the adoption of the oil return pipe, the distribution of the oil return pipe of the oil-gas separator can be optimized, the occupation space of the oil return pipe of the oil-gas separator can be reduced, an engine is compact in structure, and the miniaturization of the engine is benefited.
Description
Technical field
The utility model relates to a kind of part of automobile engine, and more particularly, it relates to a kind of oil-gas separating device for engine return tube.
Background technique
Motor is in operation process, can produce the mixture of machine oil and air in the crankcase, this mixture enters deaerator and carries out oil gas, separation, gas after the separation is entering air filter, entering intake manifold under the engine section load condition under the high engine load operating mode, the machine oil after the separation is got back to cylinder body or oil sump by the deaerator return tube.Existing deaerator return tube normally directly is connected deaerator with cylinder body or oil sump, the direct water conservancy diversion of machine oil after separating is returned cylinder body or oil sump, this circuit path is longer, return tube needs certain-length, and return tube also needs stent support, these all will take certain space, are unfavorable for the miniaturization of motor.Publication number is that the model utility of CN202187807U discloses a kind of oil sump and deaerator return tube assembly structure on April 11st, 2012, comprise the return opening that is located on the oil sump and the return tube that is communicated with it, the oil sump sidewall upper is provided with tilting boss, return opening is located on the tilting boss, the oily passage of the mistake of return opening and oil sump internal communication is shoulder hole, its epimere is screw, and hypomere is the pilot hole that mates with the return tube external diameter; Return tube was inserted in the oily passage, and its end is positioned at below the pasta; Be shaped with annular projection on the return tube, be provided with in the screw annular projection is pressed on lock sleeve on the shoulder hole transitional surface.By adopting above-mentioned assembly structure, oil outlet is promoted to more than the oil sump inner engine oil face, avoided the impact of engine oil pressure, reduced the seal request at return tube and oil sump assembling position, utilize annular projection and lock sleeve on the return tube to be fixed sealing, prevent from causing return opening the problem of lubricating oil leakage to occur because motor jolts to vibrate for a long time, thereby reduced oil consumption.This uses the machine oil after novel middle deaerator return tube will separate directly to draw the oil return drain pan from deaerator, therefore still has above-mentioned shortcoming, namely needs to reserve certain cloth tube space and support installing space, is unfavorable for the miniaturization of motor.
The model utility content
More reasonable for the component layouts that makes motor, overall structure is compacter, and the utility model provides a kind of deaerator return tube of having optimized to lay route, has improved the oil-gas separating device for engine return tube of motor level of integration.
The technical solution of the utility model is: a kind of oil-gas separating device for engine return tube, this deaerator return tube is located between the oil rule of the deaerator of motor and motor, and the deaerator return tube directly is communicated with deaerator and oil rule oil pipe.Oil rule is the device that detects oil mass in the whole engine oil recycle system of motor, oil rule is communicated with cylinder body by oil pipe, but oil rule itself is not in the oil circulation path, from deaerator return tube common on the available engine directly link the structural design of engine cylinder-body or oil sump different be, deaerator return tube in the utility model is to link on the oil pipe of oil rule, send isolated oil back to cylinder body by the oil pipe of oil rule, because isolated oil is to deliver to constantly in the oil pipe of oil rule gently, flow and oil pressure are all less, and oil rule is measured the impact of circulation oil mass not quite.The deaerator return tube is received on the oil pipe of oil rule, the oil return path can be shortened greatly, the deaerator return tube need not very long, the rigidity of pipe shaft self is enough to support deadweight, therefore can save the support of supporting oil gas separating device return tube, thereby between province's clearancen, make engine structure compacter.
As preferably, the deaerator return tube is the colloid flexible pipe, deaerator return tube two ends respectively by clip connected on deaerator and oil rule oil pipe.Use the colloid flexible pipe to be fixedly connected with end as the deaerator return tube and with clip, simple in structure, with low cost, easy for installation.
As preferably, the deaerator return tube is metal tube, and deaerator return tube two ends are connected on deaerator and the oil rule oil pipe by thread locking nut respectively.Use metal tube to be fixedly connected with end as the deaerator return tube and with thread locking nut, be connected firmly, ageing resistance is good.
The beneficial effects of the utility model are:
Optimize deaerator return tube layout, reduce the space that the deaerator return tube takies, make engine structure more compact, be conducive to the miniaturization of motor.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1-deaerator return tube, 2-deaerator, 3-oil rule, 4-cylinder body, 5-cylinder cap, 6-air filter, 7-intake manifold.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing specific embodiment.
Embodiment 1:
As shown in Figure 1, a kind of oil-gas separating device for engine return tube, this deaerator return tube 1 is located between the oil rule 3 of the deaerator 2 of motor and motor, deaerator return tube 1 directly is communicated with the oil pipe of deaerator 2 and oil rule 3, be respectively equipped with a taper joint on the oil pipe of deaerator 2 and oil rule 3, deaerator return tube 1 is rubber pipe, deaerator return tube 1 two ends are enclosed within respectively on the joint of deaerator 2 and oil rule 3 oil pipes, and tighten fixing by clip.
Embodiment 2:
Be respectively equipped with a male connection on the oil pipe of deaerator 2 and oil rule 3, and joint is provided with inner taper, deaerator return tube 1 is Stainless Steel Tube, deaerator return tube 1 two ends are installed with respectively an ozzle with external taper, and also overlap respectively on the pipe shaft behind each ozzle a tapped thread locking nut is arranged, ozzle can with the oil pipe of deaerator 2 and oil rule 3 on male connection concavo-convex adaptive, each thread locking nut also can be respectively with the oil pipe of machine oil gas separating device 2 and oil rule 3 on adaptive the screwing of male connection, deaerator return tube 1 two ends are connected on the oil pipe of deaerator 2 and oil rule 3 by ozzle and thread locking nut and male connection.
Motor is in operation process, can produce the mixture of machine oil and air in the crankcase, this mixture enters deaerator 2 by cylinder body 4 and cylinder cap 5, separated by deaerator 2, gas after the separation enters air filter 6 under the high engine load operating mode, enter intake manifold 7 under the engine section load condition, the machine oil after separating then enters the oil pipe of oil rule 3 by deaerator return tube 1, and then returns into cylinder body 4 by the oil pipe of oil rule 3.
