Abstract
The utility model relates to an engine component, in particular to a cylinder cover oil-gas separating device. The cylinder cover oil-gas separating device comprises a cylinder cover, a cover plate and a cover plate base, wherein the cover plate and the cover plate base are arranged in the cylinder cover; a plurality of groups of labyrinth baffles provided with notches in a staggered way or in an independent way are arranged between the cover plate and the cylinder cover; and an air inlet and an air outlet pipe are arranged on the cylinder cover. The cylinder cover oil-gas separating device is characterized in that a blockage pipe is arranged between the air outlet pipe and the labyrinth baffle at the tail end; the blockage pipe is communicated with the air outlet pipe; and the other end of the blockage pipe extends into the a labyrinth cavity. The cylinder cover oil-gas separating device has the characteristics of good oil-gas separating effect, reliable working, simple structure, strong practicality, lower production cost, etc.
Description
Technical field
The utility model relates to a kind of engine components, especially relates to a kind of cylinder head cover gas and oil separating plant.
Background technique
As everyone knows, the inboard design mostly of the internal combustion (IC) engine cylinder housing of Sheng Chaning in the market has labyrinth or rare filter screen to separate the machine oil in the mixed gas in the crankcase, thereby reaches the purpose of controller oil consumption and protection environment.But the oil gas separation of this structure is relatively poor, can not adapt to the needs of positive crankcase ventilation (PCV) technology; Even disposed the independent gas and oil separating plant of good separation, also can make the filter screen in the independent gas and oil separating plant be in abominable saturability working state, finally make the operation and maintenance cycle shortening of internal-combustion engine and the generation of a series of bad errors, particularly be unfavorable for the design and the application of gas and oil separating plant more efficiently.
Summary of the invention
The utility model mainly is short an etc. technical problem in, working life relatively poor at the existing in prior technology oil gas separation, provides that a kind of oil gas separation is good, the cylinder head cover gas and oil separating plant of reliable operation.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of cylinder head cover gas and oil separating plant, comprise cylinder head cover and be arranged on cylinder head cover interior cover plate and cover plate seat, be provided with the labyrinth baffle plate of the some groups of notches that stagger mutually or independently have between cover plate and the cylinder head cover, cylinder head cover is provided with suction port and steam outlet pipe, it is characterized in that being provided with blocking tube between described steam outlet pipe and the terminal labyrinth baffle plate, described blocking tube is communicated with steam outlet pipe, and the blocking tube the other end extends in the cavity of labyrinth.The liquid machine oil that the utility model sticks at labyrinth cavity internal channel wall and the blocking tube structure that designs, it can not only prevent to greatest extent that the liquid machine oil in the cylinder head cover is inhaled into gas handling system, and it is cheap for manufacturing cost, making is simple, oil gas separation is good.
As preferably, described blocking tube and the labyrinth inwall that extends in the cavity of labyrinth do not have point of contact.The part that blocking tube extends in the cavity of labyrinth does not contact with the labyrinth inwall, has avoided liquid machine oil to flow out from the air outlet along blocking tube effectively.
As preferably, fix by several screws or rivet between described cover plate and the cover plate seat, form labyrinth channel.It is simple in structure, practical and manufacture cost is cheap relatively.
As preferably, described cover plate punching press has several oil-collectings depressions, is provided with spill port in the minimum point of depression, fixedlys connected with an end of several U or V-arrangement return tube respectively, and lower plane and valve cage that the return opening of the other end is lower than cover plate communicate.The labyrinth channel that cover plate and valve-chamber cover are connected to form, the oil-collecting depression on the cover plate and oil return U or V-arrangement pipe can make the liquid machine oil that is attached in the labyrinth channel be back in the crankcase more smoothly.
As preferably, described blocking tube is the extension of steam outlet pipe in the labyrinth, is connected or extends connection with vertical between the steam outlet pipe.Can select to install the Placement of blocking tube and steam outlet pipe according to the practical structures of internal combustion (IC) engine cylinder housing, its features simple structure, practical; Blocking tube also can be arranged in the notch of baffle plate between the 2 air chambers, and the periphery sealing is reliable, forms labyrinth channel, and the extension is towards a side of air inlet.
Characteristics such as therefore, the utlity model has that oil gas separation is good, reliable operation, simple in structure, practical and manufacture cost are cheap relatively.
