Description
Technical field
The present invention relates to a kind of forced ventilation one-way valve for automotive engine.
Background technique
Motor car engine comprises intake manifold, cylinder cover, cylinder body, oil pan, is connected to gas handling system on the intake manifold, is connected to ventilation system on the cylinder cover.
Gas handling system comprises the air induction hose that closure, pressurized machine, air-strainer and an end and intake manifold are joined, closure, pressurized machine, air-strainer are successively set in the air induction hose and the close intake manifold of closure, and the other end of air induction hose communicates with atmosphere.
Ventilation system comprises exhaust hose that an end and cylinder cover join, is arranged on deaerator and forced ventilation one-way valve in the exhaust hose, the other end of exhaust hose links to each other with air induction hose in the gas handling system by forced ventilation one-way valve and is in after the air-strainer (promptly this one-way valve is between the air-strainer of deaerator, gas handling system of ventilation system), and the oil outlet of deaerator joins by oil pipe and oil pan.Forced ventilation one-way valve plays measure control, and this one-way valve is made of parts such as valve body, plunger type valve and springs, and the material of valve body is the PCV material.
During engine operation, after gas of combustion (being gas mixture) in the cylinder body filters by deaerator, clean gas flows in the air induction hose (being commonly called as gas blowby) through this one-way valve, and separated liquid oil is back in the oil pan by oil pipe, reuses.When motor generation tempering, this one-way valve is wanted to cut off air inlet, prevents the cylinder body blast.
This one-way valve opens and closes by spring control and its keying degree is regulated by the degree of vacuum of intake manifold, is forced to suck gas handling system to participate in the flow of burning thereby regulate gas blowby.Because the cracking pressure less (only being several mbar) of this one-way valve, the vibration of motor will make spring shake, thereby makes that the keying of plunger type valve is irregular, down to the keying state labile of this one-way valve, influences the proper functioning of motor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of forced ventilation one-way valve for automotive engine, and this one-way valve can not be subjected to the influence of engine luggine, and its keying state is comparatively stable.
In order to solve the problems of the technologies described above, the invention provides a kind of forced ventilation one-way valve for automotive engine, it comprises valve gap, valve seat, valve block, forms valve pocket between valve gap, valve base sealing connection and valve gap, the valve seat, valve seat, valve pocket, valve gap communicate successively, and valve block places in the valve pocket;
Valve seat is the cylinder of a both ends open, its side near valve gap has some first spokes, first wheel, first spoke circumferentially is distributed in inwall and its common plane of end face near valve gap of valve seat, and first wheel is installed in the inner of first spoke and protrudes towards the direction of valve gap;
Also be provided with the blocking blade that valve block is played barrier effect in the valve pocket, there is first placement hole with the first wheel Spielpassung at the center of blocking blade, also have some air holes on the blocking blade, vertically be provided with two anti-rotary columns with arbitrary first spoke Spielpassung on the side of blocking blade;
There is second placement hole with the first wheel Spielpassung at the center of valve block, and the material of valve block is an elastic material;
Valve gap is the cylinder of a both ends open, its side near valve seat has some second spokes, second wheel hub, second spoke circumferentially is distributed in the inwall of valve gap, second wheel hub is installed in the inner of second spoke and protrudes towards the direction of valve seat, and there is the pit that cooperates with first wheel the outer end of second wheel hub;
First wheel penetrates in first placement hole, two anti-rotary columns are respectively across the both sides of arbitrary first spoke width direction, make blocking blade paste and be placed on first spoke near on the end face of valve gap, valve block passes to abut on the blocking blade and with blocking blade behind the first wheel by second placement hole and hides, make valve pocket be divided into two chambers, first wheel inserts in the pit, and the outer end of second wheel hub contacts with the center region of valve block.
For can concise description for the purpose of the problem, below forced ventilation one-way valve for automotive engine of the present invention be all abbreviated as this one-way valve.
This one-way valve is the same with existing forced ventilation one-way valve, also is mounted in the ventilation system of motor car engine, and is between the air-strainer of deaerator, gas handling system of ventilation system.
During engine operation, gas way flow is successively crossed valve seat, blocking blade, valve block, valve pocket, valve gap, valve block is towards the direction resiliently deformable of valve gap, as seen, this one-way valve system controls keying by the resiliently deformable of valve block and its keying degree is regulated by the Young's modulus of valve block, is forced to suck gas handling system to participate in the flow of burning thereby regulate gas blowby.
After adopting above structure, second wheel hub, valve block, blocking blade, first spoke contacts successively, make valve block pass through second wheel hub, blocking blade obtains axially locating and can't move axially, one side of blocking blade is by the valve block and second wheel hub, opposite side obtains axially locating by first spoke and can't move axially, blocking blade is also circumferentially located by anti-rotary column and can't circumferentially be rotated, like this, blocking blade can not shaken during engine luggine, thereby make that the keying of valve block is regular, so that engine luggine greatly reduces the influence degree that one-way valve opens and closes state, can not influence the proper functioning of motor.
Therefore, this one-way valve can not be subjected to the influence of engine luggine, and its keying state is comparatively stable.
Described valve block is a silicone rubber for circular and its material.
Described blocking blade is circular, and anti-rotary column is near the first placement hole place, and air hole consequently forms some first placement hole and inside and outside concentric ring-type breathe freely rings of centering on along the circumferential arrangement of blocking blade.
Described second spoke is the inclined-plane near the end face of valve seat.Like this, can reduce resistance, be convenient to gas and flow through valve gap smoothly.
Described valve gap and valve seat form a corresponding side of valve pocket for expanding part.Like this, can give the resiliently deformable of valve block with enough spaces.
