Abstract

The utility model discloses a kind of turbocharger oil return pipe component, including back leakage connection and seal nipple, described back leakage connection have axially through T-shaped hole, the outer wall that one end is taken in oil return has the external screw thread being connected with pressurizer oil mouth, the other end of back leakage connection is tightly connected with seal nipple one end, and the oil return opening of the other end and engine cylinder cap or camshaft chest of seal nipple is tightly connected.The utility model processing is simple, and assembly process process is high, due to eliminating conventional flange connection and oil return gasket seal, therefore simple in construction, and weight and cost are low, also in the absence of solder joint dropping situations, and reliability is high, is conducive to the oil return of horizontal engine booster.

Description

Turbocharger oil return pipe component

Technical field

The utility model is related to technical field of engines, especially a kind of turbocharger oil return pipe component.

Background technology

Turbocharger is because it in terms of improving engine power, improving discharge with preferable effect to obtaining extensively Using.Due to supercharger speed and operating temperature is higher, it is necessary to which machine oil is lubricated to its bearing, cooled down, after lubrication Machine oil flows into crankcase or oil sump by the gravity of itself by pressurizer oil pipe assembly.Notification number is A kind of oil return pipe disclosed in CN201220600788.6, its part is more, complicated, add oil return pipe of supercharger weight and Cost；Hard oil pipe is connected with flange welding, and hard oil tube thickness is required, and solder joint is easy to fall off, and sealing is poor；Flange upper surface Contacted with booster, there are certain roughness requirements to contact surface, as engine structure is more and more compacter, oil return pipe of supercharger The installing space on road is less and less, and pipeline of the prior art is difficult to arrange, for horizontal engine, return line level The longer easy generation oil return of section is not smooth, and causes turbocharger from turbine and the oil leak of compressor both sides, causes turbocharging Device failure.And the installation of the return line structure disclosed in notification number CN201320847579.6, oil return pipe and flange is cumbersome, such as Fruit oil return pipe is bend pipe, is just more difficult to assembling, installing has more requirement to assembly space, at the same it is many there is also number of parts, into This high many deficiency.

Utility model content

The technical problems to be solved in the utility model is：Overcome deficiency in the prior art there is provided a kind of simplified structure, just In the turbocharger oil return pipe component for installing, improving engine oil return patency.

The utility model solves the technical scheme that its technical problem used：A kind of turbocharger oil return pipe component, Including back leakage connection and seal nipple, described back leakage connection have axially through T-shaped hole, oil return takes over the outer wall tool of one end There is the external screw thread being connected with pressurizer oil mouth, the other end and seal nipple one end of back leakage connection are tightly connected, seal nipple The oil return opening of the other end and engine cylinder cap or camshaft chest be tightly connected.

Specifically, described seal nipple includes steel pipe and is coated on the rubber layer of outer wall of steel pipe, and rubber layer front end has Preceding bulge loop, rubber layer rear end has rear bulge loop, and described preceding bulge loop external diameter is more than the diameter macropores of T-shaped hole, the rear bulge loop External diameter is more than the diameter of oil return opening on cylinder head or camshaft chest.

Further, described rubber layer is integrally formed using vulcanizing treatment with steel pipe.

The beneficial effects of the utility model are：The utility model processing is simple, and assembly process process is high, due to eliminating in the past Flange connection and oil return gasket seal, thus it is simple in construction, and weight and cost are low, can also in the absence of solder joint dropping situations It is high by property, be conducive to the oil return of horizontal engine booster.

Brief description of the drawings

The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.

Embodiment

The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.

A kind of turbocharger oil return pipe component as shown in Figure 1, overall vertical direction is installed, including the He of back leakage connection 1 Seal nipple 2, described back leakage connection 1 have axially through T-shaped hole 3, oil return adapter 1 at the aperture of T-shaped hole 3 outside Wall has the external screw thread being connected with pressurizer oil mouth, and the other end of the back leakage connection 1 at the macropore of T-shaped hole 3 connects with sealing First 3 one end is tightly connected, and the oil return opening of the other end and engine cylinder cap or camshaft chest of seal nipple 3 is tightly connected.

Specifically, described seal nipple 3 includes steel pipe 4 and is coated on the rubber layer 5 of the outer wall of steel pipe 4, and rubber layer 5 is used Vulcanizing treatment is integrally formed with steel pipe 4, has preceding bulge loop 6 positioned at the front end of rubber layer 5, and the rear end of rubber layer 5 has rear bulge loop 7, institute The external diameter of preceding bulge loop 6 stated is more than the diameter macropores of T-shaped hole 3, and the external diameter of the rear bulge loop 7 is more than cylinder head or camshaft chest last time The diameter of hydraulic fluid port.

The front end of back leakage connection 1 is connected by external screw thread with pressurizer oil mouthful, make-up torque, in the outer surface of seal nipple 2 Rubber layer 5 uniformly smear lubricating grease after, the preceding bulge loop 6 of the front end of seal nipple 2 is extruded to the T-shaped hole 3 of the rear end of oil inlet and oil return adapter 1 Macropore interior sealing is connected, and the insertion cylinder head of rear bulge loop 7 of the rear end of seal nipple 2 or the oil return opening of camshaft chest are tightly connected, Because caoutchouc elasticity is larger, it is unlikely to deform and damages, good sealing effect, so as to serve preferably connection and sealing effect.

The utility model processing is simple, and assembly process process is high, due to eliminating conventional flange connection and oil return pad Sealing, thus it is simple in construction, and weight and cost are low, also in the absence of solder joint dropping situations, and reliability is high, is conducive to horizontal engine The oil return of booster.

Above-mentioned embodiment is only to illustrate technical concepts and features of the present utility model, and its object is to allow be familiar with this skill The personage of art can understand content of the present utility model and be carried out, and protection model of the present utility model can not be limited with this Enclose, all equivalent change or modifications made according to the utility model Spirit Essence should all cover in protection model of the present utility model In enclosing.
