The utility model is suitable for the mechanical electronic injection air damper.

Description

A kind of mechanical electric injecting air damper

Technical field

The utility model relates to a kind of automotive engine air intake system parts, and more particularly, it relates to a kind of mechanical electric injecting air damper.

Background technique

Closure is to control one controllable valve that air enters engine, after entering suction tude, mix with gasoline, become burning mixture, participate in work by combustion, closure is the most important parts of current electric jet vehicle engine system, his top is air-strainer, and bottom is engine cylinder-body, is the throat of motor car engine.Whether car accelerates flexible, is relative with the clean of closure.

At present, mechanical electric injecting air damper on market (application number is that 201120491070.3 Chinese patent discloses a kind of gasoline engines structure), it comprises tb, throttle plate pin, throttle blade, the swing frame assembly, torsion spring, position transducer, support and stepper motor, throttle plate pin is arranged on tb by bearing, one section extension is stretched out tb, on throttle plate pin outside stretching out tb, be arranged on successively lining, torsion spring and swing frame assembly, position transducer, support and stepper motor are arranged on tb, at engine intake manifold and throttle body, be connected with seal ring, on seal ring, increased reticular structure, this structure and seal ring one are the sealing filter screen, can blocking like this freezes enters intake manifold, after having avoided gas handling system to freeze, enter the probability of engine interior, promoted the service behaviour of motor.

This closure has added the sealing filter screen, although after in use can avoiding gas handling system to freeze, enter the probability of engine interior, promoted the service behaviour of motor, still, described sealing filter screen has just solved the problem of freezing and entering motor that prevents.The volatilization of being heated of machine oil in motor car engine, contain when oil vapor arrives suction tude and turn cold, contain oil vapor and just can condense on intake duct and closure, the carbon deposit thereupon be mingled with in steam also can be deposited on these positions, particularly can be deposited on the inwall and throttle blade of throttle body.And, the current impurity of the air-strainer of automobile in can not 100% ground filtered air, a lot of impurity still can enter in motor by closure, accumulate over a long period, will have influence on the normal operation of closure, thereby make motor can not get at work due air inflow, more affect the service behaviour of motor car engine.

The model utility content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of and can prevents closure volume oil, carbon distribution and stop air plankton to enter the mechanical electric injecting air damper of motor.

For achieving the above object, the utility model provides following technological scheme: a kind of mechanical electric injecting air damper, comprise tb, throttle blade and the throttle plate pin rotated be used to driving throttle blade, described throttle plate pin is arranged on tb by bearing, described throttle body is provided with the connection end for the connecting engine suction tude, described connection end is provided be used to preventing from containing oil vapor and is infected with the filter screen that tb and air plankton enter motor, described filter screen comprises, lower two-layer, upper strata is the air-filtering layer, lower floor is fume-filtering layer.

By adopting technique scheme, described filter screen is divided into air-filtering layer and fume-filtering layer, and the air-filtering layer prevents that enough outside air plankton from entering motor,, fume-filtering layer can stop motor to include oil vapor to be infected with tb.

The utility model further is set to: described connection end comprises be used to locating the groove of filter screen.

By adopting technique scheme, utilize groove location filter screen can increase the soundness of filter screen, when a large amount of air enters motor by air supply channel rapidly, can not destroy the fixing of filter screen.

The utility model further is set to: in described groove, be provided with the jump ring for fastening filter screen.

By adopting technique scheme, the location filter screen that jump ring can ground, jail, easy to use, and also jump ring belongs to a kind of of fastening piece, and versatility is high, and application is wide.

The utility model further is set to: described air-filtering layer is the micropore filter paper through RESIN FINISH, and described fume-filtering layer is stainless steel filtering net.

By adopting technique scheme, the micropore filter paper porous of process RESIN FINISH, loose, folding, certain mechanical strength and water resistance are arranged, have that filtering efficiency is high, simple in structure, lightweight, cost is low, easy maintenance, stainless steel filtering net is hard, easy cleaning, long service life, be that the main flow in market is filtered oil network.

Embodiment

Referring to figs. 1 through Fig. 4, a kind of mechanical electric injecting air damper embodiment of the utility model is described further.

As shown in Figure 1 and Figure 4, a kind of mechanical electric injecting air damper, comprise tb 1, throttle blade 11 and the throttle plate pin 12 rotated be used to driving throttle blade 11, described throttle plate pin 12 is arranged on tb 1 by bearing 13, described throttle body is provided with the connection end 14 for the connecting engine suction tude, described connection end 14 is provided be used to preventing from containing oil vapor and is infected with the filter screen 2 that tb 1 and air plankton enter motor, described filter screen 2 comprises, lower two-layer, upper strata is air-filtering layer 21, lower floor is fume-filtering layer 22, can either prevent that outside air plankton from entering motor, can stop again motor to include oil vapor and be infected with tb 1, described filter screen 2 is divided into air-filtering layer 21 and fume-filtering layer 22, can protect simultaneously tb 1 and motor car engine.
