Embodiment
Further specify the present invention below in conjunction with drawings and Examples.
Embodiment: the present invention includes the valve rod 1 that is provided with the first defining flange 11 and the second defining flange 12, be enclosed within on the valve rod 1 and the valve body 2 between the first defining flange 11 and the second defining flange 12, and the control gear of control valve rod 1 action, also be provided with the 3rd defining flange 13 on the valve rod 1, be enclosed within successively on the valve rod 1 and the spring 3 between the second defining flange 12 and the 3rd defining flange 13, moving runner 6, movable pulley 5, be enclosed within on the valve rod 1 and the 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 respectively the 3rd defining flange 13 and moving runner 6, limited wheel 4 one ends are connected with valve body 2, limited wheel 4 inwalls evenly are provided with many group positioning blocks 41 vertically, be equipped with locating slot 42 between many group positioning blocks 41, every group of positioning block 41 comprises the first sector unit 411 that an end is the inclined-plane setting and connects successively, the 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, be provided with groove 43 between the first sector unit 411 and the 3rd sector unit 413, movable pulley 5 one end outer walls are along circumferentially evenly being provided with a plurality of boss 51 that cooperate with locating slot 42 and groove 43, the other end edge is provided with dentation structure 52, moving runner 6 is along circumferentially evenly being provided with a plurality of limit daiss 61 that cooperate with dentation structure 52, the height H of limit dais 61 is higher than the thickness h of movable pulley 5 outer walls and an end of limit dais 61 is the inclined-plane, positioning block 41 has four groups, and limit dais 61 has four.
Control gear comprises that gang switch 7, the first switch 8, second switch 9, the first switches 8 and second switch 9 control respectively the first air-conditioning A and the second air-conditioning B, 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 is not worked, and idle-speed-enhancing valve is not worked, valve rod 1 displacement L=0, and throttle control handle corner α=0, Idling Process for Diesel Engine is n
0Air-conditioning switch A path, air-conditioning A work, idle-speed-enhancing valve work, displacement of valve rod L=L
1Or L
2In valve rod 1 displacement process, moving runner 6 contacts first entirely with movable pulley 5 inclined-planes, both are without rotation trend, when moving runner 6 enters limited wheel 4, moving runner 6 contacts with limited wheel 4 inclined-planes and slides, 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, moving axially of limited wheel 4 restriction moving runners 6, thereby 1 displacement of restriction valve rod, at this moment valve rod 1 displacement is L
1When limit dais 61 slipped into locating slot 42, limited wheel 4 did not limit moving axially of moving runner 6, and valve rod 1 displacement is not affected 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
2At this moment, can be by pressing gang switch 7, make the disconnected once electricity of idle-speed-enhancing valve, after the outage, valve rod 1 will be got back to initial position, and in the return process, moving runner 6 partly contacts first with movable pulley 5, has the trend of relatively rotating, after moving runner 6 broke away from limited wheel 4, moving runner 6 relative slidings wheel 5 rotated, and became full contact by the part contact, limit dais 61 positions change, because gang switch 7 is normal open switch, thus idle-speed-enhancing valve cut off the power supply first, in power process, moving runner 6 rotates, again after the energising, moving runner 6 enter limited wheel 4 radial position different will switch on from the last time time, thereby realize the change of valve rod 1 stroke, drive the difference of oil pump handle rotation angle, realized the variation of idling.
