Abstract
Take valve mechanism cover of reed check valve, including the cover body, its characterized in that: the cover body includes cylinder shroud and baffle assembly, and baffle assembly directly imbeds in the cylinder shroud, baffle assembly includes the baffle, clamp plate and reed, and reed and clamp plate riveting are on the baffle. The utility model discloses a multiplicable leakproofness, the state that makes the gasoline engine crankcase be in the negative pressure all the time reduces engine oil consumption, and energy -conservation is the environmental protection more.
Description
Technical field
The utility model relates to a kind of valve mechanism cover with reed one-way valve.
Background technique
The valve mechanism cover that existing petrol engine band is breathed is all be placed on dividing plate with bakelite pad, covers a pressing plate above, and bakelite pad is movable in the middle of dividing plate and pressing plate, and has gap between dividing plate and pressing plate.Once petrol engine is started working, due to poorly sealed between bakelite pad and dividing plate, can not ensure that crankcase for petro engine is in the state of negative pressure all the time, cause leakage of oil serious, consumption of lubricating oil strengthens.
Summary of the invention
The purpose of this utility model is the shortcoming existed to overcome prior art, provides a kind of valve mechanism cover with reed one-way valve.
The technological scheme that the utility model will be dealt with problems is as follows:
With the valve mechanism cover of reed one-way valve, comprise cover body, it is characterized in that: described cover body comprises cylinder cover and baffle assembly, baffle assembly directly embeds in cylinder cover; Baffle assembly comprises dividing plate, pressing plate and reed, and reed and pressing plate are riveted on dividing plate.
Described reed thickness is less than 0.5mm.
Described reed is fitted on dividing plate completely.
Described pressing plate bending forms, comprise a bottom, two bottom sides sidewall and extend to the alice on both sides from both sides sidewall, a described alice is parallel to that bottom extends laterally, another alice is parallel to laterally after bottom extends and extends perpendicular to bottom.
The beneficial effects of the utility model are as follows:
This reality is novel increases sealing, makes crankcase for petro engine be in the state of negative pressure all the time, reduce engine oil consumption, energy-conservation more environmental protection.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of baffle assembly described in Fig. 1;
Fig. 3 is the schematic cross-section of Fig. 2.
Embodiment:
Below in conjunction with accompanying drawing, elaboration detailed is further done to the utility model.
Consult Fig. 1 to Fig. 2, the valve mechanism cover of band reed one-way valve, comprise cover body, described cover body (1) comprises cylinder cover (1) and baffle assembly (2), and baffle assembly (2) directly embeds in cylinder cover (1); Baffle assembly (2) comprises dividing plate (3), pressing plate (4) and reed (5), and reed (5) and pressing plate (4) are riveted on dividing plate.
Described reed (5) thickness is less than 0.5mm.
Described reed (5) is fitted on dividing plate completely.
Consult Fig. 3, described pressing plate (4) bending forms, comprise a bottom, two bottom sides sidewall and extend to the alice on both sides from both sides sidewall, a described alice is parallel to that bottom extends laterally, another alice is parallel to laterally after bottom extends and extends perpendicular to bottom.
Principle of the present utility model is as follows:
When petrol engine works, reciprocating motion of the pistons, crankcase intracavity pressure can produce fluctuation, will produce lubricating oil leakage when pressure is higher; And now, the valve mechanism cover of band reed one-way valve can be opened automatically with regard to reed, air inlet, regulates casing internal air pressure and atmospheric pressure to balance; When crankcase pressure is lower than atmospheric pressure (i.e. negative pressure), reed cuts out, and machine oil can not spill, just define an one-way valve between reed and dividing plate, effectively ensure that crankcase for petro engine is under negative pressure all the time, reduce machine oil loss, energy saving, environmental protection again simultaneously.
