Abstract
The utility model discloses a power source for a vacuum actuator of a length-changeable intake manifold, which is characterized by comprising a vacuum pot. A first connector on the vacuum pot is connected to an electromagnetic valve through an air source tube, the electromagnetic valve is serially connected between the vacuum actuator and the air source tube, a second connector on the vacuum pot is connected with a check valve through an air conveying tube, and the check valve is connected between the air conveying tube and the intake manifold of an engine and is in a conducting state for air flowing out from the vacuum pot and in a closed state for air flowing back to the vacuum pot. Negative pressure generated in the intake manifold of the engine in inspiration of a cylinder when the engine is in operation is used as the power source of the vacuum actuator, no external power is needed, space is greatly saved, light is reduced, cost is reduced, and negative factors caused by external vacuum power sources can be effectively reduced.
Description
Technical field
The utility model relates to engine accessory power rating, the setting of the vacuum actor power source of a kind of variable-length intake manifold of more specifically saying so.
Background technique
The output characteristics of naturally aspirated engine such as power, moment of torsion, oil consumption are closely related with the pipe range and the rotating speed of intake manifold to a great extent, and in general, when intake manifold was longer, middle low-speed performance performance better; More in short-term, the high speed performance performance better in intake manifold.In order to take into account this two states, development in recent years goes out variable-length intake manifold, and long tube and short tube are realized switching on certain specified point of middling speed, to guarantee optimized output characteristics.Use vacuum actor to be executive component in the handoff procedure, with the switching between vacuum actor promotion changing valve realization long tube and the short tube.
In the prior art, the way that is equipped with the routine of power source for vacuum actor spare is the vacuum pump that a band vacuum tank is set separately, is used for producing vacuum.But in concrete the application, the mode in this set extrinsic motive source is not only because of increasing cost, more brings adverse factors because of interpolation equipment takes up space and gains in weight.
The model utility content
The utility model is for avoiding above-mentioned existing in prior technology deficiency, a kind of vacuum actor power source of variable-length intake manifold is provided, cylinder suction produces negative pressure for doing moving source when utilizing engine operation in intake manifold, thereby simplify the configuration of external vacuum power source, reduce volume, weight reduction, weaken because the unfavorable factor that the external vacuum power source of configuration is brought.
The utility model technical solution problem adopts following technological scheme:
The utility model discloses a kind of vacuum actor power source of variable-length intake manifold, its structural feature is that a vacuum tank is set, first interface is connected to solenoid valve by the source of the gas pipe on the described vacuum tank, and described solenoid valve series connection is arranged between vacuum actor and the source of the gas pipe; Second interface connects one-way valve by pneumatic tube on the described vacuum tank, described one-way valve is connected in series between pneumatic tube and the engine intake manifold, described one-way valve is on state for the air-flow that flows out from vacuum tank, is off state for the gas that refluxes in vacuum tank.
The structural feature of the vacuum actor power source of the utility model variable-length intake manifold is that also described vacuum tank and engine intake manifold are integrated on the same body.
Compared with the prior art, the utility model beneficial effect is embodied in:
When 1, the utility model utilizes engine operation, the negative pressure that produces in starting intake manifold because of cylinder suction is as the power source of vacuum actor, need not to be equipped with separately extrinsic motive, saved space and weight reduction greatly, reduced cost, effectively weakened because the unfavorable factor that the external vacuum power source of configuration is brought.
2, the utility model is integrated in vacuum tank and engine intake manifold on the same body, makes simple compact, the good integrity of complete machine structure.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 engine intake manifold; 2 pneumatic tubes; 3 source of the gas pipes; 4 one-way valves; 5 vacuum tanks; 6 vacuum actors; 7 solenoid valves.
Embodiment
Referring to Fig. 1, in the present embodiment, the integrated vacuum tank 5 that is provided with on the body of engine intake manifold 1, first interface is connected to solenoid valve 7 by source of the gas pipe 3 on the vacuum tank 5, and solenoid valve 7 series connection are arranged between vacuum actor 6 and the source of the gas pipe 3; Second interface connects one-way valve 4 by pneumatic tube 2 on the vacuum tank 5, and one-way valve 4 is connected in series between pneumatic tube 2 and the engine intake manifold 1; One-way valve 4 is on state for the air-flow that flows out from vacuum tank 5, is off state for the gas that refluxes in vacuum tank 5.
During engine operation, engine cylinder produces negative pressure, attract air to participate in burning through pneumatic tube 2, one-way valve 4 and engine intake manifold 1 flow direction engine cylinder successively from vacuum tank 5, so continuous effect just makes and formed a vacuum source in vacuum tank 5.When vacuum final controlling element 6 needed action, solenoid valve 7 was opened, and the negative pressure in the vacuum tank 5 drives vacuum actor 6 by source of the gas pipe 3 and produces action.
Claims (2)
1. the vacuum actor power source of a variable-length intake manifold, it is characterized in that being provided with a vacuum tank (5), last first interface of described vacuum tank (5) is connected to solenoid valve (7) by source of the gas pipe (3), and described solenoid valve (7) series connection is arranged between vacuum actor (6) and the source of the gas pipe (3); Last second interface of described vacuum tank (5) connects one-way valve (4) by pneumatic tube (2), described one-way valve (4) is connected in series between pneumatic tube (2) and the engine intake manifold (1), described one-way valve (4) is on state for the air-flow that flows out from vacuum tank (5), is off state for the gas that refluxes in vacuum tank (5).
2. the vacuum actor power source of variable-length intake manifold according to claim 1 is characterized in that described vacuum tank (5) and engine intake manifold (1) are integrated on the same body.
