The cylinder head cover has the characteristics of high production efficiency, good refluxing effect, a simple manufacturing process, a simple structure, relatively low manufacturing cost and the like.
Description
Technical field
The utility model relates to a kind of engine cylinder head system shade assembly, especially relates to a kind of cylinder head cover machine oil reflux assembly.
Background technique
As everyone knows, labyrinth oil gas separator has mostly been designed in the inboard of internal combustion (IC) engine cylinder housing in the market, forms labyrinth channel by lid, cover plate.Design on the cover board has the oil-collecting depression and colludes the return tube of shape, collude the lowest part that the shape return tube is welded on oil-collecting depression, like this, the machine oil by labyrinth wall retaining formation liquid state down enters when caving in through oil-collecting and colludes the shape return tube, flow out from the another port, reach the purpose of backflow.But this structure not only has higher technical requirements to welding procedure, and manufacturing efficiency is lower.The most important thing is that because long oil return tube wall has hindered the flowing velocity of machine oil, the backflow efficient in the unit time is not high.Particularly when oil and gas content increased, this structure can't satisfy the operation needs of internal-combustion engine, can cause the generation of a series of problems such as engine oil consumption increase.
Summary of the invention
The utility model mainly is that, backflow weak effect lower at existing in prior technology manufacturing efficiency, manufacturing process are loaded down with trivial details, the technical problem of complex structure etc., and the cylinder head cover machine oil reflux that a kind of manufacturing efficiency is higher, backflow is effective, manufacturing process is easy, simple in structure assembly is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of cylinder head cover machine oil reflux assembly, comprise cylinder head cover and be arranged on cover plate on the cylinder head cover, offer oil and gas import on the cover plate, constituted gas channel between cylinder head cover and the cover plate, it is characterized in that described cover plate is provided with one or more oil return cones, oil return cone inboard is provided with the trapped fuel cavity, offer spill port on the wall of described trapped fuel cavity, be respectively arranged with one or more blocking tubes in the described gas channel.The oil return cone that employing is provided with the trapped fuel cavity replaces original shape return tube that colludes, and has increased the oil return effect greatly, has effectively improved the backflow efficient in the unit time, and simple in structure, make easy.
As preferably, described trapped fuel cavity engages formation by two longitudinal walls with a plate, and described plate is provided with oil inlet hole perpendicular to an end of oil return cone base, and is lower than the level height of described spill port.When two longitudinal walls and the trapped fuel cavity that forms a fluid potential difference after plate engages, described trapped fuel cavity is realized refluxing its backflow efficient height, simple in structure by the spill port on its wall.
As preferably, described gas channel front end is provided with blocking tube, and described blocking tube is vertical with gas channel to be provided with.Blocking tube can be installed on the arbitrfary point of gas channel inside, and the tube wall of blocking tube must not link to each other with conduit wall, and its skirt body has the effect of air chamber at interval.
As preferably, described gas channel end is provided with the outlet blocking tube, and described outlet blocking tube is vertical with gas channel to be provided with.The extension that described outlet blocking tube can be a steam outlet pipe is vertical with gas channel to be provided with, and also can independently be arranged at the terminal inboard of gas channel, and the tube wall of blocking tube must not link to each other with conduit wall, and its skirt body has the effect of air chamber at interval.
As preferably, fix by several screws or rivet between described cylinder head cover and the cover plate.Connect tight, simple in structure, manufacturing efficiency is high and cheap for manufacturing cost.
As preferably, described oil return cone, cover plate, blocking tube adopt PA or rubber material manufacturing.Single injection-molded is simplified production technology, manufacture cost is cheap relatively and weight is lighter.
Therefore, the utlity model has that manufacturing efficiency is higher, backflow is effective, manufacturing process is easy, simple in structure, characteristics such as manufacture cost is cheap relatively.
