Abstract
A control device for synchronous negative pressure control over a lubricating hole through a piston structurally comprises a cylinder sleeve, the lubricating hole, a valve plate, the piston, a spring, a vent hole and the like. The control device is characterized in that the through lubricating hole is drilled in the position 10-20 mm to the right of the left side of the top of the cylinder sleeve, the vent hole is designed from the cylinder wall into the cylinder sleeve and in straight-through connection with the lubricating hole, the piston is installed in the vent hole and connected with the valve plate through a pull rod, one end of the spring abuts against the piston, and the other end of the spring abuts against the cylinder sleeve. The control device has the advantages that by means of reciprocating motion of the piston of an engine, the lubricating hole can be controlled to be opened and closed, the lubricating oil concentration during work of the piston of the engine is guaranteed, and the service life of a large-discharge-cavity air cylinder is prolonged.

Denomination of invention: the control gear of piston synchronous vacuum cavitations lubrication hole.
Technical field
The present invention relates to the cylinder oil control gear of gasoline four-stroke engine, is a kind of control gear of piston synchronous vacuum cavitations lubrication hole 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 control gear of piston synchronous vacuum cavitations lubrication hole, 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 control gear of this kind of piston synchronous vacuum cavitations lubrication hole, and its structure comprises: radiating fin, cylinder sleeve, casing wall, fastener hole, lubrication hole, oil guide slot, valve block, piston, spring, pore.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, in cylinder sleeve, a pore is designed with at casing wall, pore passes straight through to lubrication hole, the inside of pore is provided with piston, piston is connected with valve block by pull bar, and spring one end withstands piston, and the other end withstands cylinder sleeve.
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 when pore is covered in the skirt section of the piston of motor, the gas in pore is taken out of, the elastic force of piston overpowers spring moves right, and lubrication hole is closed by valve block;
When the descent of piston of motor, negative pressure in crankcase disappears, piston top in spring handle pore goes back to the left side, valve block leaves lubrication hole, 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.
