In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is Embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.

Fig. 1 is structural representation of the present utility model；Fig. 2 is the sectional view of the line A-A along Fig. 1.

Reference: 1 idling valve body, 2 motors, 3 air inlet pipe, 4 escape pipes, 5 control valve .6 screw mandrels, 7 pistons, 8 spiral shells Hole, 9 gib blocks, 10 gathering sills, 11 annular boss, 12 sealing rings, 13 anticorrosive coats.

Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Based on the enforcement in this utility model Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into The scope of this utility model protection.

Engine idling controlling device, as it can be seen, include that the upper end of the idling valve body 1 with air throttle partial installation is installed Motor 2, the lower end of idling valve body 1 connects air inlet pipe 3, and air inlet pipe 3 connects air filter, and the periphery of idling valve body 1 sets There is several escape pipe 4；Installing control valve 5 on escape pipe 4, the output shaft of motor 2 connects vertical screw mandrel 6, idling valve body 1 Inside being provided with piston 7, the top of piston 7 is cylindrical, and the bottom of piston 7 is inverted cone platform, the top of piston 7 and idling valve body 1 Inwall coordinate, piston 7 is positioned at the mouth of pipe of escape pipe 4, offers vertical screw 8 in piston 7, and screw 8 coordinates with screw mandrel 6, The inwall vertical gib block 9 of fixed installation of idling valve body 1, the periphery of piston 7 offers vertical gathering sill 10, gib block 9 with Gathering sill 10 coordinates.In this utility model, control screw mandrel 6 by motor 2 and rotate, so that piston 7 can be along idle valve Body 1 moves up and down, when the inverted cone platform of piston 7 bottom is positioned at the mouth of pipe of escape pipe 4, and escape pipe 4, idling valve body 1 and enter Trachea 3 forms path, thus realizes connection, and the position according to piston 7 is different, and the area of escape pipe 4, idling valve body 1 connection is also Different such that it is able to effectively control air inflow the most processed.According to the quantity of cylinder, connect escape pipe 4, for being not connected with cylinder The control valve 5 of escape pipe 4 end can be closed, and therefore this utility model is multiple escape pipes 4, it is adaptable to single cylinder, twin-tub or The automobile of multi-cylinder.

Specifically, the automobile cylinder quantity of the air inlet diameter use corresponding to this utility model of air inlet pipe 3 is relevant, for The situation of multi-cylinder, needs to change the air inlet pipe 3 of bigger air inlet diameter, changes for convenience, the idle valve described in the present embodiment The lower end periphery of body 1 is provided with external screw thread, and the upper end of air inlet pipe 3 is provided with female thread, is screw thread between air inlet pipe 3 and idling valve body 1 Connecting, the top of air inlet pipe 3 inwall is provided with annular boss 11, is provided with sealing between the bottom of annular boss 11 and idling valve body 1 Circle 12.During replacing, air inlet pipe 3 is screwed off, the air inlet pipe 3 of new major diameter is screwed on, is sealed by sealing ring 12 Process, it is to avoid gas leakage.

Concrete, in order to reduce the corrosion to piston 7 of the compositions such as oil gas, improve service life, the work described in the present embodiment One layer of anticorrosive coat 13 of periphery coating of the inverted cone platform of the bottom of plug 7.

Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit； Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: Technical scheme described in foregoing embodiments still can be modified by it, or carries out wherein portion of techniques feature With replacing；And these amendments or replacement, do not make the essence of appropriate technical solution depart from this utility model each embodiment technology The spirit and scope of scheme.
