Abstract
The utility model discloses an air intake and exhaust channel structure of a clutch booster of a vehicle. The air intake and exhaust channel structure comprises a valve, wherein an air inlet valve seat and a control valve rod are arranged in the valve, vent holes are formed in the valve, an air valve is arranged in the air inlet valve seat, and a return spring is arranged on the air valve. The air intake and exhaust channel structure is characterized in that a circle of circular airflow channel is arranged at the bottom of the valve, the circular airflow channel is communicated with the vent holes, the vent holes are formed in the outer edge of the circular airflow channel, air inlets are formed in the circumferential face of the outer circle of the air inlet valve seat, an exhaust channel is arranged at the bottom of the air inlet valve seat, and the exhaust channel is communicated with the vent holes and the circular airflow channel.
Description
Technical field
The utility model relates to the channel design of vehicle clutch booster intake and exhaust.
Background technique
Mostly the intake and exhaust channel of existing vehicle clutch booster is to be often directly communicated with the air cavity of valve body, not only processed complex of this intake and exhaust structure, and rate of fault is high, and easily occurs the problems such as intake and exhaust instability of flow.
Summary of the invention
The purpose of this utility model is to design a kind of vehicle clutch booster intake and exhaust channel structure.
To be solved in the utility model is the intake and exhaust channel structure processed complex of existing vehicle clutch booster, and rate of fault is high, and easily occurs the problems such as intake and exhaust instability of flow.
The technical solution of the utility model is: it comprises valve body, in valve body, be provided with inlet valve seat and control valve rod, valve body is provided with exhaust port, in inlet valve seat, be provided with air valve, air valve is provided with return spring, it is characterized in that valve body bottom is provided with a circle annular air-flow path, this annular air-flow path is communicated with and is positioned at the outer rim of annular air-flow path with exhaust port, inlet valve seat cylindrical circumferential surface is provided with inlet hole, the bottom of inlet valve seat is provided with exhaust passage, and this exhaust passage is communicated with exhaust port, annular air-flow path is communicated with.
At least two of inlet holes on inlet valve seat cylindrical circumferential surface, and be distributed on inlet valve seat cylindrical circumferential surface.The exhaust passage of inlet valve seat bottom is inclined open type structure.
The utility model has the advantages that: the utility model is simple and convenient, service time is long, be conducive to improve gas flow characteristic, ensure the stable of intake and exhaust throughput.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model inlet valve seat sectional drawing.
Fig. 3 is the utility model inlet valve seat plan view.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in the figure, the utility model comprises valve body 1, is provided with inlet valve seat 6 and controls valve rod 4 in valve body 1, and valve body 1 is provided with exhaust port 3, is provided with air valve 7 in inlet valve seat 6, and air valve 7 is provided with return spring 8.Valve body 1 bottom is provided with a circle annular air-flow path 2, and this annular air-flow path 2 and exhaust port 3 are communicated with and are positioned at the outer rim of annular air-flow path 2.Inlet valve seat 6 cylindrical circumferential surfacies are provided with inlet hole 9, and the bottom of inlet valve seat 6 is provided with exhaust passage 5, and this exhaust passage 5 is communicated with exhaust port 3, are also communicated with annular air-flow path 2.
The inlet hole that inlet valve seat cylindrical circumferential surface is provided with is two, is distributed on inlet valve seat 6 cylindrical circumferential surfacies, is symmetrically distributed on inlet valve seat 6 cylindrical circumferential surfacies.The exhaust passage 5 of inlet valve seat 6 bottoms is inclined open type structure.
Working principle of the present utility model is: control the switching of air valve 7 by controlling valve rod 4, open air valve 7 in the time that control valve rod 4 moves down.When air valve 7 is under return spring 8 effect when return, air valve 7 is closed; Air valve 7 is for controlling the break-make of booster source of the gas.
