Implement motor car engine auxiliary air intake device of the present utility model, have following beneficial effect: motor car engine auxiliary air intake device of the present utility model has the valve mechanism of opening under predetermined pressure, can under the situation of motor air feed deficiency, open automatically, cause adverse consequences because of air feed is not enough to avoid motor.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the preferred embodiment of motor car engine auxiliary air intake device of the present utility model.
Embodiment
Understand for technical characteristics of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1, a preferred embodiment for motor car engine auxiliary air intake device of the present utility model, comprise a cylindrical shell 10, be provided with a dividing plate 11 in the cylindrical shell 10, the top of dividing plate 11 is provided with and is provided with a dividing plate 11 in the cylindrical shell 10 that is used for filtered air, dividing plate 11 is provided with gas port 111, the upper end of cylindrical shell 10 is fixed with a loam cake 20, has inlet hole 221 on the loam cake 20, the lower end of cylindrical shell 10 is fixed with lower cover 30, lower cover 30 has a socket end 31, and socket end 31 is connected with the suction tude of motor by conduit, and dividing plate 11 also has the valve mechanism of opening when surpassing predetermined pressure.
In the present embodiment, valve mechanism on the dividing plate 11 comprises the cone shape hole 112 that is arranged on dividing plate 11 centers, spool 50 and the turriform spring 60 adaptive with cone shape hole, the bigger side of cone shape hole 112 openings is towards lower cover 30, the turriform spring withstands on the spool 50 for 60 1 sections, the other end withstands on the lower cover 30, and lower cover 30 has the spring seat 32 adaptive with turriform spring 60.Spool 50 comprise core 51 with conical surface 511 with and the valve rod 52 that is connected with core 51, the top of turriform spring 60 is enclosed within the outside of valve rod 52.The area of gas port 111 is less than the area of described cone shape hole 112.
In the present embodiment, loam cake 20 is threaded with the upper end of cylindrical shell 10, and lower cover 30 is threaded with same employing the in the lower end of cylindrical shell 10.Loam cake 20 comprises lid 21 and the connecting wall 22 that is extended by lid downwards, inlet hole 221 is arranged on the connecting wall 22, the angle 222 of the axis of the axis of inlet hole 221 and cylindrical shell 10 is an acute angle, can avoid liquid such as water to have inlet hole 221 to enter in the cylindrical shell 10 like this.
