Abstract
The invention relates to the technical field of automobile oil supply systems, and provides a novel one-way valve. The novel one-way valve comprises a valve body which is in the shape of a tube and made of flexible materials with a memory effect, one end of the valve body is provided with an oil inlet portion which is connected with an oil return tube, the other end of the valve body is provided with an oil outlet portion which is provided with an opening, and the initial state of the opening is naturally closed. When engine oil separated from an oil-mist separator of the oil return tube is stored to be a certain height, the opening of the oil outlet portion of the one-way valve opens due to the pressure of the engine oil, and the engine oil outflows through being affected by gravity action. When flow of spurt gas of the oil-mist separator increases, the pressure drop of gas delta p increases, the oil-mist separator is affected by the pressure, due to the fact that the one-way valve is made of the flexible materials with the memory effect, the opening returns to the initial state due to the memory effect, the one-way valve is closed, and the engine oil is prevented from being brought out of the oil-mist separator by the gas.
Description
Technical field
The present invention relates to automobile oil supply system technical field, be specifically related to one-way valve.
Background technique
This year, automobile industry also must along with low-carbon (LC), environmental protection along with the raising of worldwide environmental consciousness, energy-conservation trend development.But the requirement of Consumer to car steering and Safety performance is more and more higher, the development trend of automobile is also improving and Engine Downsizing future development towards motor unit discharge capacity power.
In engine combustion process, the gas of leaping up (Blow-by) of the generation in cylinder can be spilt by piston ring portion, except having the sufficient gas of unburned, moisture in gas of leaping up, beyond other harmful gases, and some gasoline.In order to prevent machine oil stained, the excessive friction of engine movements parts, the bad problem such as scaling loss, need to be separated gas of leaping up, by the machine oil return meeting motor of leaping up in gas, the sufficient gas of unburned is poured suction system into and is rekindled, and this device is oil mist separator.
Gas of leaping up carries out in the process be separated by oil mist separator, and the pressure △ p of some gas can lose, and therefore in order to can oil return smoothly, the height of usual return tube sets according to △ p.Because △ p and separation effect are directly proportional, expect higher separation effect, △ p just needs very large, so just requires that the height of return tube is more and more higher.
And mention in above-mentioned background, under the prerequisite that overall engine is more and more compacter, the space leaving return tube for is difficult to guarantee, therefore one-way valve is applied to height return tube reducing return tube.Current most one-way valve is usually minimum by valve block, and the plural parts of return tube are formed, the parts also having fixing valve block had.Valve block is produced by hard material (such as engineering plastics) or soft material (such as rubber) usually.Such one-way valve structures is complicated, and part is many, and versatility is bad.
Summary of the invention
The object of the invention is to, a kind of Novel check valve is provided, to solve the problem.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of Novel check valve, is characterized in that, comprises one in a tubular form and by the valve body having memory effect flexible material and make, one end of described valve body is provided with an oil-feed portion, and described oil-feed portion is connected with return tube; The other end of described valve body is provided with a fuel-displaced portion, and described fuel-displaced portion is provided with an opening;
Described opening original state is Natural closure shape.
When the machine oil be separated from oil mist separator in return tube is stored into certain altitude, due to the pressure of machine oil, the fuel-displaced portion opening of one-way valve opens, machine oil gravitate and flowing out.When oil mist separator along with the throughput that leaps up increases, gas pressure drop △ p also can increase, and be stressed impact, and one-way valve forms owing to adopting memory effect flexible material, and opening, due to memory effect, gets back to original state, closed check valve.Prevent machine oil from being taken out of oil mist separator by gas.
The aperture in described oil-feed portion is not more than the external diameter of described return tube.So that the valve body of flexible material of the present invention is installed on return tube.
Described fuel-displaced portion comprises two V-type regions, and during described V-type joint area, described opening is Natural closure shape; When described V-type region disconnects, described opening is in opening shape.The present invention, by the opening and closing of fuel-displaced portion opening, realizes the break-make of one-way valve.
During described V-type joint area, described fuel-displaced portion inner chamber is a cone type.
The most advanced of described fuel-displaced portion inner chamber is provided with a slender type groove, and described groove is positioned at the tip central authorities of described V-type region inner chamber.When one-way valve inner engine oil pressure is excessive, by described groove so that outward opening opens.
As a kind of preferred version, the cross section of described groove is a right-angled trapezium, and described trapezoidal upper base is not more than 2cm, and described trapezoidal going to the bottom is not more than the wall thickness of described valve body.
As another kind of preferred version, the cross section of described groove is a right-angled triangle, and two right angle sides of described right-angled triangle are all not more than the wall thickness of described valve body.
Accompanying drawing explanation
A kind of structural representation when Fig. 1 is valve body conducting of the present invention;
Fig. 2 is a kind of structural representation in valve body of the present invention cross section when closing.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below in conjunction with concrete diagram.
With reference to Fig. 1, Fig. 2, a kind of Novel check valve, a kind of Novel check valve, comprises one in a tubular form and by the valve body having memory effect flexible material and make, one end of valve body is provided with an oil-feed portion 2, and oil-feed portion 2 is connected with return tube; The other end of valve body is provided with a fuel-displaced portion 1, and fuel-displaced portion 1 is provided with an opening; Opening original state is Natural closure shape.When the machine oil be separated from oil mist separator in return tube is stored into certain altitude, due to the pressure of machine oil, the fuel-displaced portion opening of one-way valve opens, machine oil gravitate and flowing out.When oil mist separator along with the throughput that leaps up increases, gas pressure drop △ p also can increase, and be stressed impact, and one-way valve forms owing to adopting memory effect flexible material, and opening, due to memory effect, gets back to original state, closed check valve.Prevent machine oil from being taken out of oil mist separator by gas.
