Description
Technical field
The utility model belongs to the component technical field of motor, is specifically related to the length-adjustable intake manifold of a kind of gas-entered passageway.
Background technique
Because motor is in the intermittence of intake process and periodicity, for meeting the motor demand that motor changes pressure wave frequencies under high and low rotating speed, the length-adjustable system of gas-entered passageway is adopted to make motor use short gas-entered passageway when high rotating speed, in, the slow-speed of revolution uses longer gas-entered passageway, thus optimizes the performance of motor under high and low rotating speed.Gas-entered passageway adjustable length intake manifold all needs a set of control mechanism to realize the switching of long tube and short tube.As the notification number utility model patent that is CN202039989U discloses a kind of vacuum actor power source of variable-length intake manifold, vacuum tank (for control mechanism provides vacuum power) is wherein for being integrated in the non-dismountable structure in intake manifold, and connecting pipeline is rubber pipe.Due to the non-removable vacuum tank of integrated form break down time, often cannot change separately, need during maintenance to change whole intake manifold, maintenance cost is very high.In addition, common rubber pipe not only heavier-weight, and long rubber pipeline manufacture cost higher, easily there is the integrity problems such as ageing failure.
Model utility content
The purpose of this utility model is exactly the defect for prior art, provides a kind of gas-entered passageway length-adjustable intake manifold.
The technical solution adopted in the utility model is: comprise intake manifold and vacuum tank, on described vacuum tank, first interface is connected to solenoid valve by the first pipeline, described solenoid valve is arranged in series between final controlling element and described first pipeline, on described vacuum tank, the second interface is connected to one-way valve by the second pipeline, described one-way valve is arranged in series between described second pipeline and described intake manifold, described vacuum tank is fixed on intake manifold outside, described first pipeline is formed by connecting by some sections of rubber pipes and some sections of plastic tubes, and described second pipeline is rubber pipe.
Further, be provided with fixed base bottom described vacuum tank, described fixed base has bolt hole, described vacuum tank is by fixing with intake manifold after bolt passing through bolt hole.
Further, described first pipeline two ends are rubber pipe, and centre combines for some sections of rubber pipes and some sections of plastic tubes.
The gas-entered passageway adjustable length intake manifold of the detachable vacuum tank of the utility model and one-way valve, and the pipeline in control mechanism is plastic tube and rubber pipe composite structure, entirety achieves the reliability of maintenance convenience and Geng Gao.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another angled arrangement schematic diagram of the utility model.
In figure, 1-intake manifold; 2-vacuum tank; 3-solenoid valve; 4-final controlling element; 5-one-way valve; 6-the first pipeline; 7-the second pipeline; 8-bolt.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form restriction to the utility model.
As Fig. 1, shown in Fig. 2, the utility model comprises intake manifold 1 and vacuum tank 2, on described vacuum tank 2, first interface 2.1 is connected to solenoid valve 3 by the first pipeline 6, described solenoid valve 3 is arranged in series between final controlling element 4 and described first pipeline 6, on described vacuum tank 2, the second interface 2.2 is connected to one-way valve 5 by the second pipeline 7, described one-way valve 5 is arranged in series between described second pipeline 7 and described intake manifold 1, it is outside that described vacuum tank 2 is fixed on intake manifold 1, described first pipeline 6 is formed by connecting by some sections of rubber pipes 6.1 and some sections of plastic tubes 6.2, described second pipeline 7 is rubber pipe.Described first pipeline 6 two ends are rubber pipe, and centre combines for some sections of rubber pipes 6.1 and some sections of plastic tubes 6.2.
In such scheme, bottom described vacuum tank 2, be provided with fixed base 2.3, described fixed base 2.3 have bolt hole 2.4, described vacuum tank 2 by bolt 8 through fixing with intake manifold 1 after bolt hole 2.4.
The utility model vacuum tank 2 is connected with the first pipeline 6 and the second pipeline 7, second pipeline 7 connects pressure stabilizing cavity rear end in intake manifold 1, because motor is in running, can produce larger degree of vacuum in pressure stabilizing cavity, vacuum tank 2, by being connected with pipeline herein, obtains vacuum pressure; First pipeline 6 is connected with final controlling element 4, and on this pipeline, be provided with a solenoid valve 3, this solenoid valve 3 is controlled to open or close by ECU, when this solenoid valve 3 is opened, vacuum tank 2 and final controlling element 4 are connected, the diaphragm spring of final controlling element 4 moves down, and the control valve of intake manifold 1 inside is closed, and gas-entered passageway is elongated; When this solenoid valve 3 cuts out, final controlling element 4 and vacuum tank 2 disconnect, and the diaphragm spring of final controlling element 4 moves, and the control valve of intake manifold 1 inside is opened, and gas-entered passageway shortens.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
