The end of one end that the gear shaft stretches out outside cabinet is designed to the shape of handle, facilitates manual operation；
The course of work: switching device is separately mounted to the air inlet and exhaust ports of cylinder, by cabinet outside handle control
Gear movement processed, gear are engaged with the rack gear on two blocks of its two sides simultaneously, the two blocks is driven to transport round about
It is dynamic.Therefore idler wheel of two side block blocks on respective track rolls together with block along respective track in the opposite direction.When
The block moved upwards has encountered positive stop lug boss, this block no longer rises；Meanwhile the block moved downward encountered cylinder into
Port, moving downward for the block is also restrained, no longer declines；
Beneficial effect
1, compared with miniature rotor engine on the market, valve timing regulator disclosed by the invention realizes height
Under two kinds of revolving speeds, the switching of valve timing.So that speed operation has having big valve overlap in high-speed working condition
Small valve overlap.
2, compared with the distribution of big-block engine is adjusted, air inlet phase regulating mechanism disclosed by the invention is not necessarily to control system
Intervention, stablize simple.
3, valve timing switching device of the invention can be reduced pumping loss, improve the output performance and fuel oil warp of engine
Ji property.
4, the device of the invention is easy to accomplish, at low cost, long service life.

Embodiment 1
For miniature rotor engine high and low rotating speed distribution switching device, comprising: gear 1, block 2, positive stop lug boss 3,
Gear shaft 4 and cabinet 5；
Cabinet 5 is the square structure on top and low side opening；Gear shaft 4 passes through 5 side wall of cabinet, and gear shaft 4 passes through bearing
Seat is fixed on 5 side wall of cabinet, need to guarantee that gear 1 is placed in 5 center of cabinet, and parallel with cabinet 5；1 two sides of gear are respectively at gear
Block 2 engages；Block 2 is rectangular parallelepiped structure, is disposed with rack gear on the side center that block 2 is engaged with gear 1；Block 2 exists
Gear 1 can move up and down under acting on along 5 side wall of cabinet；Positive stop lug boss 3 is placed in the highest point that block 2 moves upwards, to guarantee
Block moves upwards the height no more than design；
2 low side of block is streamlined structure, streamlined structure and contact area (block 2 and cylinder contact area) gas
The shape of cylinder molded line is identical；
Track is disposed on 5 side wall of cabinet, block 2 is transported above and below 5 side wall of cabinet in orbit under the effect of gear 1
It is dynamic；
The track is that the three side sealing that three vertical planes being fixed on 5 side wall of cabinet are constituted closes shape, and two of them are perpendicular
Width between straight parallel surface is of same size with block 2；
It is disposed with pulley on the block 2 and the contact surface of cabinet 5 and track, reduces the frictional resistance of up and down motion；
