Abstract

The utility model discloses a cover plate assembly integrating an oil return pipeline and an oil baffle air outlet pipe. The cover plate assembly comprises a cover plate main body, and an exhaust pipe, an oil return pipe and an oil baffle piece which are arranged on the cover plate main body. And the oil baffle piece is mounted at the opening of the exhaust pipe. And one side of the oil baffle piece, which is over against the opening of the exhaust pipe, is provided with an oil guide inclined surface which is inclined downwards. Due to the fact that the oil blocking piece with the oil guiding inclined face inclining downwards is arranged at the opening of the exhaust pipe, when liquid oil in an oil tank splashes towards one side of the exhaust pipe, the liquid oil is blocked through the oil blocking piece, and the oil is guided to fall back through the oil guiding inclined face on the oil blocking piece. Loss of oil liquid is reduced while burden on a filter element in the exhaust pipe is reduced.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile parts, and particularly relates to a cover plate assembly integrated with an oil return pipeline and an oil blocking and air outlet pipe. BACKGROUND

[0002] In the existing oil delivery system, oil is delivered through piston movement or cam movement. Under the influence of piston movement, the gas mixed in the oil in the oil tank gradually expands. To ensure that the air pressure in the tank is balanced during use, an air outlet hole is formed on the oil tank, and an exhaust pipe is arranged to ensure that the air pressure inside and outside the tank is balanced.

[0003] Under the influence of piston movement, the oil in the oil tank will move circumferentially along the inner wall of the oil tank, causing splashing of the oil. The splashed liquid oil is easy to enter the exhaust pipe and be discharged synchronously with the output gas. The outflow of the liquid oil in the oil tank will increase the burden of the filter element at the outlet of the breather pipe, reducing the service life of the filter element. SUMMARY

[0004] To make up for the shortcomings of the prior art, the utility model provides a cover plate assembly integrated with an oil return pipeline and an oil blocking and air outlet pipe to solve the technical problem that splashed liquid oil is easy to enter the exhaust pipe.

[0005] To achieve the above-mentioned purposes, the specific technical scheme of the utility model is as follows:

[0006] A cover plate assembly integrated with an oil return pipeline and an oil blocking and air outlet pipe, comprising a cover plate body, and an exhaust pipe, an oil return pipe and an oil blocking piece installed on the cover plate body. The oil blocking piece is installed at the opening of the exhaust pipe. The side of the oil blocking piece opposite to the opening of the exhaust pipe is provided with an inclined downward oil guiding slope.

[0007] Further, the oil blocking piece is divided into a middle oil guiding part and two side shielding parts. The oil guiding slope is arranged on the oil guiding part.

[0008] Further, the oil guiding part, the shielding part and the cover plate body form a cover structure with an open bottom.

[0009] Further, the side section of the cover structure is in a triangular structure with the upper part being small and the lower part being large.

[0010] Further, the lower edge of the oil blocking piece is lower than the lower edge of the exhaust pipe.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] The utility model discloses a set up the oil baffle piece with the downward oil guide inclined plane in the opening of the exhaust pipe, when the liquid oil in the oil tank splashes to the side of the exhaust pipe, will be resisted through the oil baffle piece, and the oil liquid is guided to fall back through the oil guide inclined plane on the oil baffle piece, reduces the loss of oil liquid while reducing the burden of the filter core in the exhaust pipe. BRIEF DESCRIPTION OF DRAWINGS
