Abstract
The utility model discloses a valve chamber cover, which comprises a valve chamber cover body, a machine oil filling opening arranged on the valve chamber cover body and a maze bottom plate arranged in the valve chamber cover, wherein the front end of the maze bottom plate is extended to the position just under the machine oil filling opening. Preferably, the maze bottom plate arranged just under the machine oil filling opening covers 50 percent of the inner wall forming area of the machine oil filling opening. Because the front end of the maze bottom plate is directly extended to the position just under the machine oil filling opening to serve as an oil blocking plate and the interval between the machine oil filling opening and the maze bottom plate serving as the oil blocking plate is over 20 mm and no connection exists between the machine oil filling opening and the maze bottom plate serving as the oil blocking plate, no influence is caused to machine oil passing through the machine oil filling opening. The valve chamber cover is simple in structure, does not need to change the structure of the valve chamber cover body and the structure of the machine oil filling opening arranged on the valve chamber cover body, and is low in fabrication cost.
Description
Technical field
The utility model relates to a kind of valve chamber cover, especially relates to the valve chamber cover that is provided with the labyrinth base plate in a kind of.
Background technique
At present, valve chamber cover total performance oil filler place feature is divided two kinds, and a kind of is not have integrated oil baffle, in case getting loose appears in this structure cap, machine oil will vomit from oil filler during engine running, and motor and personnel are caused potential safety hazard; Another kind is to go out integrated oil baffle at oil filler, though the potential safety hazard that this structure has the prevention cap to get loose and cause, but it has taken the area of oil filler, influence machine oil by oil filler filling and filling speed, but also make the valve chamber cover mould become complicated more, increase manufacture cost.As Chinese patent 200720045332 disclosed a kind of cyclinder head cover cap assemblies, comprise valve chamber cover body and the oil filler that stretches out the valve chamber cover body, the oily mechanism of one retaining is set in the described oil filler, has the machine oil inlet channel between the inwall of described retaining oil mechanism and oil filler.
The model utility content
The purpose of this utility model provides a kind of valve chamber cover, and solving existing valve chamber cover oil baffle influences machine oil filling and mfg. moulding die complicated problems.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of valve chamber cover comprises valve chamber cover body and the oil filler and the intrinsic labyrinth of the valve chamber cover base plate that are arranged on the valve chamber cover body; Described labyrinth base plate front end extend to oil filler under.
Preferably, the labyrinth base plate under the described oil filler accounts for the oil filler inwall and forms 50% of area.
In order to improve oil return speed, be groove in the middle of the base plate of described labyrinth, described groove tilts to oil-return groove.
Run off in order to reduce oil gas, improve the working efficiency of porous impact plate, the internal face of described valve chamber cover body is provided with a plurality of muscle, and the porous impact plate the when position of described muscle is assembling on the base plate of labyrinth can assign into the position between two muscle.
Preferably, the height of described muscle is 5mm.
The beneficial effects of the utility model: since labyrinth base plate front end directly extend to oil filler under become oil baffle plate, again since the labyrinth base plate that becomes oil baffle with more than there is 20mm in the gap of oil filler and between without any being connected, do not estimate and can impact by oil filler machine oil.It is simple in structure, need not change the valve chamber cover body and on the structure of oil filler, low cost of manufacture.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the utility model valve chamber cover cross-sectional schematic.
Fig. 2 overlooks partial schematic diagram for the utility model valve chamber cover.
Fig. 3 is the utility model labyrinth base plate schematic top plan view.
Among the figure: 1. cyclinder head cover body, 2. oil filler, 3. labyrinth base plate, 31. labyrinth base plate front ends, 4. muscle, 5. porous impact plate, 6. groove, 7. oil-return groove, 8. spill port.
Embodiment
As depicted in figs. 1 and 2, a kind of valve chamber cover comprises valve chamber cover body 1 and the oil filler 2 and the intrinsic labyrinth of the valve chamber cover base plate 3 that are arranged on the valve chamber cover body; Described labyrinth base plate front end 31 extend to oil filler 2 under, and the labyrinth base plate under the oil filler accounts for the oil filler inwall and forms 50% of area.
Run off in order to reduce oil gas, improve the working efficiency of porous impact plate, the internal face of described valve chamber cover body is provided with a plurality of muscle 4, and the porous impact plate 5 the when position of described muscle 4 is assembling on the labyrinth base plate 3 can assign into the position between two muscle, and the height of muscle is 5mm.
As shown in Figure 3, in order to improve oil return speed, be groove 6 in the middle of the base plate of described labyrinth, described groove 6 tilts to oil-return groove 7, offers spill port 8 in the bottom of oil-return groove 7.
Since labyrinth base plate front end directly extend to oil filler under become oil baffle plate, again since the labyrinth base plate that becomes oil baffle with more than there is 20mm in the gap of oil filler and between without any being connected, do not estimate and can impact by oil filler machine oil.It is simple in structure, need not change the valve chamber cover body and on the structure of oil filler, low cost of manufacture.In addition, the existing not integrated oil filler of volume production is kept off the valve chamber cover of oily mechanism, the mould that also only needs to change the labyrinth base plate prolongs the labyrinth base plate, and the change mould time, short cost was low.
Claims (5)
1. valve chamber cover comprises valve chamber cover body (1) and is arranged on oil filler (2) and the intrinsic labyrinth of valve chamber cover base plate (3) on the valve chamber cover body; It is characterized in that: the front end of described labyrinth base plate (3) extend to oil filler (2) under.
2. valve chamber cover as claimed in claim 1 is characterized in that: the labyrinth base plate (3) under the described oil filler (2) accounts for the oil filler inwall and forms 50% of area.
