Abstract
The utility model discloses a four-stroke gasoline engine lubricating mechanism adopting a rubber one-way valve. The four-stroke gasoline engine lubricating mechanism comprises the rubber one-way valve, an oil return hole, an oil outlet chamber and a crank shaft chamber, wherein the rubber one-way valve is located on a partition between the crank shaft chamber and the oil outlet chamber, the oil return hole is located in the bottom of the oil outlet chamber, and an oil baffle plate is arranged on one side of the oil outlet chamber. The rubber one-way valve is located on the partition between the crank shaft chamber and the oil outlet chamber, so that the stroke of oil mist to the oil outlet chamber is short, oil outlet is fast, lubrication of a four-stroke gasoline engine in an original state is effectively improved, the service life of parts and components is prolonged, the machining technology is simple, and cost is low.
Description
Technical field
The utility model relates to a kind of gasoline engine lubricating mechanism, particularly relates to a kind of four-stroke gasoline engine lubricating structure that adopts rubber one way valve.
Background technique
Petrol engine (being called for short " petrol engine ") is to using gasoline as fuel, by the interior motor that can change into kinetic energy.Because gasoline viscosity is little, evaporation is fast, can gasoline be sprayed into cylinder with gasoline injection system, after overcompression reaches certain temperature and pressure, by spark ignitor, makes gas expansion for doing work.The feature of petrol engine is that rotating speed is high, simple in structure, quality is light, cheap, smooth running and easy maintenance.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of four-stroke gasoline engine lubricating structure that adopts rubber one way valve, it makes mist of oil short to the stroke that goes out oil pocket, therefore fuel-displaced fast, effectively improve four and rush lubricating under petrol engine original state, the working life of elongated component, processing technology is simple, and cost is low.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of four-stroke gasoline engine lubricating structure that adopts rubber one way valve, wherein, comprise rubber one way valve, spill port, go out oil pocket and crankshaft cavity, described rubber one way valve is at crankshaft cavity and go out on the partition between oil pocket, and described spill port is positioned at the bottom of oil pocket.
Preferably, a side that goes out oil pocket described in is provided with oil baffle.
Preferably, the outer profile of described oil baffle is shaped as curved.
Positive progressive effect of the present utility model is: the utility model makes mist of oil short to the stroke that goes out oil pocket, described rubber one way valve is at crankshaft cavity and go out on the partition between oil pocket, it makes mist of oil short to the stroke that goes out oil pocket, therefore fuel-displaced fast, effectively improve four and rush lubricating under petrol engine original state, in the working life of elongated component, processing technology is simple, and cost is low.

Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As shown in Figure 1 to Figure 3, the utility model adopts the four-stroke gasoline engine lubricating structure of rubber one way valve to comprise rubber one way valve 2, spill port 3, go out oil pocket 4 and crankshaft cavity 5, rubber one way valve 2 is at crankshaft cavity 5 and go out on the partition between oil pocket 4, and spill port 3 is positioned at the bottom of oil pocket 4.A side that goes out oil pocket 4 is provided with oil baffle 1, prevents that so liquid lubricant oil from arbitrarily flowing out.The outer profile shape of oil baffle 1 is preferably curved.
The four-stroke gasoline engine lubricating structure of the employing rubber one way valve that the utility model provides, utilization is installed on crankshaft cavity 5 and goes out the rubber one way valve 2 on the partition between oil pocket 4, controlling lubricant mist enters out oil pocket 4 from crankshaft cavity 5, utilization is going out the spill port 3 of the bottom of oil pocket 4, and liquid lubricant oil is got back in crankshaft cavity 5.
The utility model makes mist of oil short to the stroke that goes out oil pocket, therefore fuel-displaced fast, effectively improves four and rushes lubricating under petrol engine original state, and in the working life of elongated component, processing technology is simple, and cost is low.
Above-described specific embodiment; the technical problem of solution of the present utility model, technological scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
