Abstract
A lubrication device of a negative pressure control air cylinder structurally comprises a lubrication hole, a valve plate, a piston, a spring and an air channel. The lubrication device of the negative pressure control air cylinder is characterized in that the air channel penetrates through the gap between cooling fins to reach the middle of a cylinder sleeve and is communicated with the lubrication hole, the piston is installed in the part, in the cylinder sleeve, of the air channel 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 right side wall of the air channel. When an engine is in an accelerated state, elasticity of the spring is larger than negative pressure, the piston drives the pull rod, the valve plate is ejected, lubrication oil enters the lubrication hole from an oil guide groove to reach the air inlet side of the piston, and the piston drives the lubrication oil to make the air cylinder and the air inlet side of the piston covered with oil films; when the engine is in a decelerated state, the elasticity of the spring is smaller than the negative pressure, the piston is sucked, the valve plate closes the lubrication hole, and it is effectively guaranteed that when the engine is decelerated, the lubrication oil generates enough resistance on operation of the engine. The lubrication device has the advantages that control over opening and closing of the lubrication hole is achieved, fuel oil is saved, and the service life of the air cylinder is prolonged.
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 vacuum cavitations 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, motor is when slowing down, lubricant oil still enters cylinder by lubrication hole, causes the running resistance of piston during deceleration to increase, and causes the drawback of oil consumption rising 1%.
Because motor 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 vacuum cavitations cylinder, there is the controlled control of the open and close reached lubrication hole, to realize the working life saved fuel oil and extend cylinder.
The present invention realizes with following technological scheme: the lubricating fitting of this kind of vacuum cavitations cylinder, and its structure comprises: radiating fin, cylinder sleeve, casing wall, fastener hole, lubrication hole, oil guide slot, valve block, piston, spring, air flue.It is characterized in that, described air flue is formed through lubrication hole through the centre that the gap of radiating fin and radiating fin arrives cylinder sleeve and gangs up, and described piston is arranged in the air flue in cylinder sleeve, and piston is connected with valve block by pull bar, spring one end withstands piston, and the other end withstands on the You Bi side of air flue.
By flexible pipe, air flue is connected with air intake branch, after engine operation,
Under motor is in normal acceleration mode, the negative pressure of air intake branch declines, the negative pressure of air flue also declines thereupon, the elastic force of spring is greater than the pressure of negative pressure, piston driving pull bar, and valve block is ejected, the lubricant oil gushed out from connecting rod introduces by oil guide slot the air inlet side one side that lubrication hole arrives piston, piston driving lubricant oil makes the air inlet side of cylinder and piston all cover one deck oil film, effectively ensure that the concentration of lubricant oil, reaches the function improving motorcycle cylinder lubrication system.
Under motor is in deceleration regime, the negative pressure of air intake branch rises, the negative pressure of air flue also rises thereupon, the elastic force of spring is less than the pressure of negative pressure, piston is inhaled, valve block closes lubrication hole, has many lubricant oil motor to be run to the resistance caused, reach the function of saving fuel oil when effectively ensureing engine retard.
Beneficial effect, the present invention has the controlled control of the open and close reached lubrication hole, to realize the working life saved fuel oil and extend cylinder.
Accompanying drawing explanation
