Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Embodiment: the present invention includes the valve rod 1 being provided with the first defining flange 11 and the second defining flange 12, to be enclosed within valve rod 1 and valve body 2 between the first defining flange 11 and the second defining flange 12, and control the control gear of valve rod 1 action, valve rod 1 is also provided with the 3rd defining flange 13, to be enclosed within successively on valve rod 1 and spring 3 between the second defining flange 12 and the 3rd defining flange 13, moving runner 6, movable pulley 5, to be enclosed within valve rod 1 and cylindrical shape limited wheel 4 between the first defining flange 11 and the second defining flange 12, the two ends of spring 3 prop up the 3rd defining flange 13 and moving runner 6 respectively, limited wheel 4 one end is connected with valve body 2, limited wheel 4 inwall is evenly provided with many group positioning blocks 41 vertically, locating slot 42 is equipped with between many groups positioning block 41, often organize positioning block 41 comprise one end be inclined-plane arrange and the first sector unit 411 connected successively, second sector unit 412 and the 3rd sector unit 413, the gradient on inclined-plane is identical, direction is consistent, the inclined-plane of the first sector unit 411 is consistent with the bevel altitude of the 3rd sector unit 413, the inclined-plane of the second sector unit 412 extends along the inclined-plane of the 3rd sector unit 413, groove 43 is provided with between first sector unit 411 and the 3rd sector unit 413, movable pulley 5 one end outer wall is circumferentially evenly provided with multiple boss 51 coordinated with locating slot 42 and groove 43, the other end edge is provided with dentation structure 52, moving runner 6 is circumferentially evenly provided with multiple limit dais 61 coordinated with dentation structure 52, the height H of limit dais 61 is higher than the thickness h of movable pulley 5 outer wall and one end of limit dais 61 is inclined-plane, positioning block 41 has four groups, limit dais 61 has four.
Control gear comprises gang switch 7, first switch 8, second switch 9, first switch 8 and second switch 9 and controls the first air-conditioning A and the second air-conditioning B respectively, and gang switch 7 is connected with the present invention.
During use, original state: the first switch 8 and second switch 9 are all opened a way, and air-conditioning does not work, and idle-speed-enhancing valve does not work, valve rod 1 displacement L=0, throttle control handle corner α=0, Idling Process for Diesel Engine is n
0; Air-conditioning switch A path, air-conditioning A works, idle-speed-enhancing valve work, displacement of valve rod L=L
1or L
2in valve rod 1 displacement process, moving runner 6 Full connected first with movable pulley 5 inclined-plane, both are without the trend of rotation, when moving runner 6 enters limited wheel 4, moving runner 6 is with limited wheel 4 contact of incline plane and slide, moving runner 6 and limited wheel 4 are produced relative rotation, final limit dais 61 slips into locating slot 42 or is stuck on the inclined-plane of the second sector unit 412 and the 3rd sector unit 413, when limit dais 61 is stuck on the inclined-plane of the second sector unit 412 and the 3rd sector unit 413, limited wheel 4 limits moving axially of moving runner 6, thus the displacement of restriction valve rod 1, at this moment valve rod 1 displacement is L
1; When limit dais 61 slips into locating slot 42, limited wheel 4 does not limit moving axially of moving runner 6, and valve rod 1 displacement does not affect by extending means, and at this moment valve rod 1 displacement is L
2.
Because valve rod 1 displacement is indefinite, L=L
1, or L
2, idling is also uncertain, n=n
1or n
2.At this moment, by pressing gang switch 7, make the disconnected once electricity of idle-speed-enhancing valve, after power-off, valve rod 1 will get back to initial position, in return process, moving runner 6 and the first part contact of movable pulley 5, there is the trend of relatively rotating, after moving runner 6 departs from limited wheel 4, moving runner 6 relative sliding wheel 5 rotates, Full connected is become by part contact, limit dais 61 position changes, because gang switch 7 is normal open switch, so the first power-off of idle-speed-enhancing valve, in power process, moving runner 6 rotates, again after energising, moving runner 6 enter limited wheel 4 radial position different when will be energized from the last time, thus realize the change of valve rod 1 stroke, drive the difference of oil pump handle rotation angle, achieve the change of idling.
Second switch 9 path, the second air-conditioning B works, identical with above-mentioned working principle.
