Abstract
The utility model relates to a labyrinth type valve chamber cover shell, wherein a crankcase gas blowby passage is arranged on the horizontal direction of a central part of a valve chamber cover shell, and obstructing baffle plates with different lengths are installed on the inner periphery wall of the valve chamber cover shell. The labyrinth type valve chamber cover shell has simple structure and reasonable design, and a labyrinth structure capable of prolonging the retention time of gas and liquid in a separation chamber, and increasing contact area between mixed gas and the inner wall of the separation chamber is arranged in an oil gas separation chamber which consists of an oil baffle plate and the valve chamber cover shell together, and is provided with a mixed gas inlet and a filter gas outlet, crankcase gas blowby can be effectively filtered, the PCV valve working environment can be improved, and engine oil consumption can be reduced.
Description
Technical field
The utility model relates to a kind of new work engine valve cage case labyrinth type oil gas separation structure.
Background technique
At present, breathing of engine system oil gas separating device is generally independent setting, has a style of one's own, be independent of engine body, general general deaerator is filter net type and vortex type, these two kinds of deaerators all need to be connected with some external pipelines, increased the complexity that the motor peripheral accessory is arranged thus, overall cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, has reduced the mazy type valve cage case of consumption of lubricating oil.
In order to achieve the above object, the technical solution adopted in the utility model is: be provided with the crankcase blow-by gas passage in valve cage case central position substantially horizontal, obstruct baffle plate different in size is housed on its inner circle wall.
The utility model has the advantages that:
1, simple in structure, reasonable in design, in oil baffle and the common Oil-gas Separation chamber with mixed gas inlet and filtering gas outlet that constitutes of valve cage case, setting can prolong the labyrinth structure of oil gas holdup time, increase mixed gas and disengagement chamber inwall area of contact in disengagement chamber;
2, the crankcase gas blowby obtains effective filtering, has improved PCV valve working environment, has reduced consumption of lubricating oil.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to schematic representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model is provided with crankcase blow-by gas passage 2 in valve cage case 1 central position substantially horizontal, and obstruct baffle plate 3 different in size is housed on its inner circle wall.
In crankcase blow-by gas passage 2 left-hand portion the shape of falling T is housed and intercepts baffle plate 4.
The labyrinth structure of the utility model Oil-gas Separation is multiple tracks to be set intercept baffle plate 3 in the Oil-gas Separation chamber, and adjacent obstruct baffle plate 3 is interlaced with the air-flow path position that the Oil-gas Separation cavity wall forms.The crankcase gas blowby enters Oil-gas Separation labyrinth cavity by valve cage case 1 two ends, behind each obstruct baffle plate 3, enters vent hose from exporting 5.At this moment, oil gas has obtained reliable separation, and the machine oil that filters through deaerator directly flow back in the oil sump from the cylinder cap spill port.In oil baffle and the valve cage case 1 common Oil-gas Separation chamber with mixed gas inlet and filtering gas outlet that constitutes, setting can prolong the labyrinth structure of oil gas holdup time, increase mixed gas and disengagement chamber inwall area of contact in disengagement chamber.
Claims (2)
