Description
Technical field
The present invention relates to turbine box technical field, more particularly to a kind of vent valve for being used to reduce booster valve knock
Door gear.
Background technology
Turbocharging technology is the skill that an exhaust energy by engine high-temperature, high pressure changes into engine Effective power
Art.On the one hand the technology can improve engine power output；On the other hand fuel consumption can be reduced；Simultaneously because admission pressure
Increase, can improve fuel combustion, to reduce the discharge of the harmful components such as CH, CO.In addition, the technology by improve admission pressure come
Make up because the rise of height above sea level, air weaken and the charge flow rate of reduction, the rising because of height above sea level can be slowed down, under engine power
Drop.Therefore, turbocharging technology is by as the main direction of development of alternate-engine.
At present, the stronger booster of low speed acting ability is often selected when carrying out Matching of Turbocharger type selecting to engine,
Exhaust gas bypass mechanism is used during high speed, portion bypass is fallen, to avoid the hypervelocity of booster or obstruction.Referring to Fig. 1 and Fig. 2
Shown, exhaust gas bypass mechanism uses convertible deflation valve at present, i.e. valve 1 is connected with one end of rotary shaft 2, rotary shaft 2
The other end be connected with one end of swing arm 3, the other end of swing arm 3 is connected with actuator.With actuator swing arm 3 can be driven to rotate,
And then realized by rotary shaft 2 with movable valve 1 and be turned on and off moving.
But the deflation valve of said structure contacts with deflation hole wall 4 when closed, knock is also easy to produce, while is difficult real
The now accurate control of deflation valve opening, and the accurate control of deflation valve opening, can integrally lift booster performance.With row
Put that regulation is increasingly strict, be pressurized the continuous lifting of pressure ratio, booster performance is required to improve constantly, while passenger is to booster
Also more and more higher, traditional convertible deflation valve are increasingly difficult to meet to require noise requirements, therefore designing one kind can either drop
Low valve knock, and can realize the deflation valve that deflation valve opening accurately controls, and will become very significant.
The content of the invention
The present invention be directed to the convertible deflation valve of turbocharger tradition at work, due to the change of engine operating condition
Or the fluctuation of pressure at expulsion, deflation valve are needed through normally open, closing, valve is contacted with valve hole wall and is also easy to produce when closed
Knock, while convertible deflation valve is difficult to realize the accurate control of valve opening, based on this, the invention provides one kind rotation
Rotatable deflation valve.
Technical problem solved by the invention can be realized using following technical scheme：
A kind of deflation valving for being used to reduce booster valve knock, including the by-passing valve aperture of door pair with turbine box
The valve answered, it is characterised in that the valve is parallel with place plane at the top of by-passing valve aperture of door, one end of the valve and rocking arm
Connection, the middle part of the rocking arm and the rotation pin assemblies being arranged on turbine box are rotatablely connected, and the other end of the rocking arm is with holding
The front end of row device push rod is hinged, and when the actuator push rod works, is driven the rocking arm to be rotated around the rotation pin assemblies, is entered
And valve plane internal rotation where it is driven, the rotation of the valve make it that valve staggers or again with by-passing valve aperture of door
Close, so as to realize that deflation valve is turned on and off acting.
In a preferred embodiment of the invention, it is provided with anti-reverse bumping post beside the by-passing valve aperture of door.
In a preferred embodiment of the invention, it is described to rotate pin assemblies including the rotational pin through rocking arm and be set in
The elastic pressure parts on the rotational pin top and the locking nut being spun at the top of the rotational pin.
In a preferred embodiment of the invention, the elastic pressure parts are elastic pressuring plate or spring.
In a preferred embodiment of the invention, the rocking arm and valve are wholely set.
The valve of the present invention will not collide with bypath valve hole wall, can be effectively reduced booster deflation valve and valve
The knock of aperture of door wall, while the accurate control of valve opening area can be realized, so as to the accurate control to boost pressure.

Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, enter below
One step illustrates the present invention.
Be used to reducing the deflation valving of booster valve knock referring to a kind of shown in Fig. 3 and Fig. 4, including with whirlpool
Valve 20 corresponding to the by-passing valve aperture of door 11 of roller box 10, valve 20 is parallel with plane where the top of by-passing valve aperture of door 11, valve 20
It is connected with one end of rocking arm 30, the middle part of rocking arm 30 is rotatablely connected with the rotation pin assemblies 40 being arranged on turbine box 10, rocking arm
The front end of 30 other end and actuator push rod 60 is hinged.Rocking arm 30 and valve 20 are wholely set.
The side of by-passing valve aperture of door 11 in the present embodiment is provided with anti-reverse bumping post 50, when preventing that valve 20 from resetting closing
Because inertia inverts valve 20, and cause unclosed valve dead, while the anti-reverse bumping post 50 also may be used when deflation valve assembles
