Description
Technical field
The invention belongs to connecting line technical field, particularly relate between a kind of vacuum booster and motor intake manifold
Connection structure.
Background technique
Vacuum hose, for connecting vacuum booster and motor intake manifold, motor intake manifold is soft by vacuum
Pipe takes out the air inside vacuum booster, so that vacuum booster is achieved the purpose that power-assisted, vacuum hose is by nylon tube, sebific duct
And clip composition.
Air inside vacuum booster is taken out by motor intake manifold, makes vacuum booster by vacuum booster
Internal two parts generate pressure difference, so that vacuum booster be made to reach power-assisted purpose.
Motor intake manifold makes inlet manifold generate negative pressure using engine charge principle.
As depicted in figs. 1 and 2, vacuum hose one end of the prior art is connect by check valve 05 with vacuum booster 06,
One end is connect by sebific duct 02 with motor intake manifold 01, and check valve 05 makes the air of vacuum booster 06 can only be unidirectionally to hair
The flowing of 01 direction of motivation inlet manifold, and the air of motor intake manifold 01 cannot flow into vacuum booster 06, in vacuum
Nylon tube 04 is connect with sebific duct 02 in hose, and nylon tube 04 is tightened together with sebific duct 02 with clip 03.
Vacuum hose only has end to have a check valve 05 at present, if this check valve 05 fails, engine charge discrimination
The air of pipe 01 will enter in vacuum booster 06, so that vacuum booster 06 is lost power-assisted effect, seriously affect driver's
Traffic safety.For such situation, it usually needs being further added by a check valve prevents failure of check valve, but current check valve
Structure is complex, higher cost, if being further added by an identical check valve, higher cost.
When sebific duct 02 is connect with nylon tube 04 (see Fig. 2), due to 03 fastening force of clip, it is easy to appear the change of nylon tube 04
Shape causes nylon tube 04 to cause to block with appearance deformation at 03 cooperation of clip, causes motor intake manifold 01 that cannot extract very
Air in empty booster 06 prevents vacuum booster 06 from reaching power-assisted purpose, influences the traffic safety of driver.Therefore,
It needs to design a protection structure in nylon and sebific duct junction, nylon pipe plug caused by nylon tube deforms when preventing clip from fastening
Plug.

Check valve is inserted into nylon tube together with bushing, and then nylon tube is inserted into sebific duct with check valve and bushing, so
Urgent with clip afterwards, at this time due to there is bushing to support nylon tube in nylon tube, therefore when urgent clip, nylon tube will not be generated
Deformation, avoids nylon blockage, and the boss of bushing can prevent bushing, nylon tube and sebific duct to be mutually disengaged.
Non-return valve operational process is as shown in Figure 12 and Figure 13, when normal operative condition inlet manifold vacuumizes, air inlet discrimination
Pipe end generates negative pressure, and the pressure at vacuum booster end is greater than inlet manifold end at this time, and air pressure pushes in check valve at this time
First end face is mobile to inlet manifold end, and kinematic axis is in unidirectional valve opening axis to movement, and return spring is in compressive state at this time,
Air in vacuum booster is flowed to by stomata, the first venthole, the second venthole into engine air manifold end, and it is true to reach pumping
Empty purpose.
When vacuum hose failure of check valve, when motor intake manifold does not vacuumize, due to motor intake manifold at this time
Pressure be greater than vacuum booster end, gas will flow to vacuum booster end, and check valve is in air pressure and return spring at this time
Under the action of, first end face in check valve is mobile to vacuum booster end, kinematic axis in unidirectional valve opening axis to movement, first
End face is contacted with check valve installation base, and the first venthole is blocked by check valve installation base at this time, prevents air flow direction true
Empty booster end, has avoided vacuum booster failure.
The above is only the descriptions of the preferred embodiment of the present invention, it is noted that due to the finiteness of literal expression, and
Objectively there is unlimited specific structure, for those skilled in the art, is not departing from the principle of the invention
