Description
Technical field
The invention belongs to a kind of parts in technical field of engines, specifically, particularly relate to a kind of engine cylinder cover of built-in gas and oil separating plant.
Background technique
Engine fuel in the course of the work, due to the existence of operation and the piston ring gap up and down of piston, cause the pressure leakages of firing chamber to engine interior, internal engine pressures is caused to change at any time, therefore engine interior needs the connectivity structure connected with ambient atmosphere, the pressure change of balanced engine inside.In addition because engine interior exists the machine oil of lubrication, machine oil can along with the change of engine interior pressure, and the connectivity structure connected by engine interior and air is leaked to external engine, causes the disappearance of machine oil, cause engine failure, and cause environmental pollution.
Traditional motor, connectivity structure is placed on middle part or the top of motor, labyrinth structure or gas and oil separating plant are set in connectivity structure, after machine oil enters connectivity structure along with internal engine pressures changes, by labyrinth structure or gas and oil separating plant, the flowing of machine oil is hindered, make machine oil under gravity, be back to engine interior.Because engine interior pressure changes greatly, the machine oil flowed along with pressure change in motor cannot filter out by labyrinth structure or gas and oil separating plant completely, and part machine oil still can along with airflow leaks be to external engine.
Summary of the invention
In order to the machine oil flowed along with pressure change in motor cannot filter out by connectivity structure completely that solve conventional engines in prior art, cause part machine oil still along with airflow leaks is to the defect of external engine, a kind of engine cylinder cover of built-in gas and oil separating plant can be the invention provides.
The present invention is achieved by the following technical solutions:
A kind of engine cylinder cover of built-in gas and oil separating plant, comprise cylinder cap body, Oil-gas Separation room is provided with in cylinder cap body, top, Oil-gas Separation room is provided with suction tude and steam outlet pipe, Oil-gas Separation is provided with return tube bottom room, Oil-gas Separation room and cylinder cap body are respectively equipped with the labyrinth structure second and labyrinth structure first that cooperatively interact, are provided with gas and oil separating plant first in labyrinth structure first, in labyrinth structure second, are provided with gas and oil separating plant second.
Carry out first time through gas and oil separating plant first to filter, gas and oil separating plant second and the labyrinth structure second cooperatively interacted and labyrinth structure first, carry out second time to filter, oil droplet in high-pressure oil gas is separated and the negative pressure produced by the change of engine interior pressure, at the indoor generation suction of Oil-gas Separation, part oil gas in Oil-gas Separation room is sucked in the sump of motor, while avoiding oil leakage, does not affect the degassing function of connectivity structure.
Steam outlet pipe is connected with the connectivity structure on cylinder cap body.
The outlet side of suction tude is in the below of gas and oil separating plant second.
The outlet side of suction tude is arranged on the below of gas and oil separating plant second, more conveniently makes the part oil gas in Oil-gas Separation room be drawn in the sump of motor, avoids the leakage of machine oil.
Compared with prior art, the invention has the beneficial effects as follows:
Structure of the present invention is simple, easy to use, Oil-gas Separation room is arranged on engine interior, on the basis not increasing motor volume, effectively avoids oil leakage to arrive external engine.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
An engine cylinder cover for built-in gas and oil separating plant, comprises cylinder cap body 1, is provided with Oil-gas Separation room 2 in cylinder cap body 1, and top, Oil-gas Separation room 2 is provided with suction tude 6 and steam outlet pipe 7, and steam outlet pipe 7 is connected with the connectivity structure 8 on cylinder cap body 1; Return tube 3 is provided with bottom Oil-gas Separation room 2, Oil-gas Separation room 2 and cylinder cap body 1 are respectively equipped with the labyrinth structure second 10 and labyrinth structure first 5 that cooperatively interact, be provided with gas and oil separating plant first 4 in labyrinth structure first 5, in labyrinth structure second 10, be provided with gas and oil separating plant second 9; The outlet side of suction tude 6 is in the below of gas and oil separating plant second 9.
Gas and oil separating plant comprises gas and oil separating plant first 4 and gas and oil separating plant second 9, and gas and oil separating plant adopts the gas-liquid filteration net folding of 40-100 to form.
The present invention in use, with motor with the use of, return tube 3 communicates with the engine oil chamber of motor, and Oil-gas Separation room 2 is bolted on cylinder cap body 1.During work, the high-pressure oil gas that engine interior produces is after the gas and oil separating plant first 4 in labyrinth structure first 5 is filtered, enter in Oil-gas Separation room 2 by suction tude 6, after the filtration of gas and oil separating plant second 9, oil droplet in high-pressure oil gas is separated, simultaneously by the negative pressure of engine interior pressure change generation, suction is produced in Oil-gas Separation room 2, the suction produced due to engine running and the acting in conjunction of gravity, part oil gas in Oil-gas Separation room 2 is made to be drawn in the sump of motor by return tube 3, gas after filtration is by steam outlet pipe 7, discharge after connectivity structure 8.
