Abstract
A lubricating fitting for leaf valve control steam cylinder, its structure comprises: cylinder, cylinder sleeve, lubrication hole, oil guide slot, valve block, screw.It is characterized in that, the turn right position of 10mm ~ 20mm of cylinder sleeve top left side is drilled with the lubrication hole of a logical eye, and screw covers on lubrication hole fastening for valve block.When the piston rest of motor, valve block resets, and lubrication hole is closed by valve block; When the piston stroking upward of motor, produce negative pressure in crankcase, along with piston up of motor, negative pressure is along with increase, and valve block is still in correcting plane position, and lubrication hole is closed by valve block; The pressure produced after the descent of piston of motor, valve block is backed down, valve block is spacing by crankcase, the lubricant oil gushed out from connecting rod introduces by oil guide slot the air inlet side one side that lubrication hole arrives the piston of motor, and the piston driving lubricant oil of motor makes the air inlet side of the piston of cylinder and motor all cover one deck oil film; Circulation like this, thus effectively ensure the concentration of lubricating oil of the piston of motor when doing work.
Description
Technical field
The present invention relates to the cylinder oil control gear of gasoline four-stroke engine, is a kind of lubricating fitting of leaf valve control steam cylinder concretely.
Background technique
Horizontal engine of motorcycle, its cylinder top rear, near the position of crankcase, because lubricant oil splash is not in place, causes the piston of cylinder near air inlet side and cylinder to be pulled, has a strong impact on the working life of cylinder.
The patent of invention that claimant applied on July 16th, 2012, the patent No. is a kind of Novel cylinder of 2012102452023, the problem of pulling at the piston and cylinder that solve cylinder air inlet side is well solved, due to, piston is in up process, lubricant oil still enters cylinder by lubrication hole, causes running resistance during descent of piston to increase, causes the drawback of oil consumption rising 1%.
Because large-duty engine is under load operation, need more lubricant oil, and when normally travelling, too much lubricant oil will cause piston running resistance to increase, and cause the drawback that oil consumption is risen.
Summary of the invention
The object of the present invention is to provide a kind of lubricating fitting of leaf valve control steam cylinder, have and effectively ensure the concentration of lubricating oil of the piston of motor when doing work, reach the function extending huge discharge cylinder working life.
The present invention realizes with following technological scheme: the lubricating fitting of this kind of leaf valve control steam cylinder, and its structure comprises: cylinder, cylinder sleeve, lubrication hole, oil guide slot, valve block, screw.It is characterized in that, the turn right position of 10mm ~ 20mm of cylinder sleeve top left side is drilled with the lubrication hole of a logical eye, and screw covers on lubrication hole fastening for valve block.
When the piston rest of motor, valve block resets, and lubrication hole is closed by valve block;
When the piston stroking upward of motor, produce negative pressure in crankcase, along with piston up of motor, negative pressure is along with increase, and valve block is still in correcting plane position, and lubrication hole is closed by valve block;
The pressure produced after the descent of piston of motor, valve block is backed down, valve block is spacing by crankcase, the lubricant oil gushed out from connecting rod introduces by oil guide slot the air inlet side one side that lubrication hole arrives the piston of motor, and the piston driving lubricant oil of motor makes the air inlet side of the piston of cylinder and motor all cover one deck oil film;
Circulation like this, thus effectively ensure the concentration of lubricating oil of the piston of motor when doing work.
Beneficial effect is, the present invention has the to-and-fro motion of the piston by motor, realizes the control of the open and close to lubrication hole, thus ensures the concentration of lubricating oil of the piston of motor when doing work, and reaches the function extending huge discharge cylinder working life.

Fig. 2 is that a kind of descent of piston valve block of lubricating fitting of leaf valve control steam cylinder opens schematic diagram.
1. cylinders, 2. cylinder sleeve, 3. lubrication hole, 4. oil guide slot, 5. valve block, 6. screw in figure.
Embodiment
Figure of description is a kind of tectonic maps of lubricating fitting of leaf valve control steam cylinder, its structure by: cylinder 1, cylinder sleeve 2, lubrication hole 3, oil guide slot 4, valve block 5, screw 6 form.In specification Fig. 1,2, the turn right position of 10mm ~ 20mm of cylinder sleeve 2 top left side is drilled with the lubrication hole 3 of a logical eye, and screw 6 covers on lubrication hole 3 fastening for valve block 5.
The top, left side of described lubrication hole 3 to cylinder sleeve 2 has an oil guide slot 4.
The width of described oil guide slot 4 left end is wider than the internal diameter of lubrication hole 3 one times.
The overall width of described oil guide slot 4 also can be consistent with the internal diameter of lubrication hole 3.
The degree of depth of described oil guide slot 4 is 2/3rds of cylinder sleeve 2 thickness.
Described valve block 5 can cover lubrication hole 3 completely.
A screw hole is had near the position of cylinder 1 body at cylinder sleeve 2.
Described screw hole is used for and the secure fit of screw 6.
Described valve block 5 is a plane.
