Abstract
A push rod for controlling a lubricating device of a cylinder by negative pressure comprises a valve plate, a piston, a plurality of oil holes and a pull rod, and is characterized in that the piston is connected with the valve plate via the pull rod; and the through oil holes are formed in the pull rod and are close to the valve plate. The push rod is arranged in an air channel in a cylinder liner; one end of a spring is abutted to the piston; and the other end of the spring is abutted to a right wall side of the air channel. The push rod for controlling the lubricating device of the cylinder by the negative pressure has the advantages that the negative pressure which is generated with the aid of an air inlet branch or a crankcase drives the piston, so that the valve plate slides between an oil guiding groove and a lubricating hole, and an effect of controlling opening or closing of the lubricating hole is achieved.
Description
Technical field
The present invention relates to the push rod of the cylinder oil control gear of gasoline four-stroke engine, is a kind of push rod for vacuum cavitations cylinder lubrication device 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%.
On above-mentioned basis, inventor is perfect further again can be controlled lubrication hole and close and the automatic controller opened, and the parts of the application are two patent of invention in order to application before coordinating.
Summary of the invention
The object of the present invention is to provide a kind of push rod for vacuum cavitations cylinder lubrication device, 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: this kind of push rod for vacuum cavitations cylinder lubrication device, and its structure comprises: valve block, piston, oilhole, pull bar form.It is characterized in that, piston is connected with valve block by pull bar, has the oilhole of several through hole at pull bar near the position of valve block.
Described piston is arranged in the air flue in cylinder sleeve, and spring one end withstands piston, and the other end withstands on the You Bi side of air flue,
Beneficial effect, the present invention has the negative pressure produced by air intake branch float chamber, drives piston, valve block is slided between oil guide slot and lubrication hole, realizes the control action of unlatching to lubrication hole or closedown.

Embodiment
Fig. 1 is the scheme of installation of the present invention at a kind of ' lubricating fitting of vacuum cavitations cylinder '.
Fig. 2 is the scheme of installation of the present invention at a kind of ' control gear of piston synchronous vacuum cavitations lubrication hole '.
Fig. 1,2 is schematic diagram that the present invention is arranged in the air vent channel of the cylinder sleeve of above-mentioned two patents.
Accompanying drawing 3,4 is tectonic mapss of a kind of push rod for vacuum cavitations cylinder lubrication device of the present invention, and its structure is made up of valve block 1, piston 2, oilhole 3, pull bar 4.In specification Fig. 1,2, piston 2 is connected with valve block 1 by pull bar 4, has the oilhole 3 of several through hole at pull bar 4 near the position of valve block 1.
The aperture of described oilhole 3 is 3mm.
Described oilhole 3 is arranged side by side.
The total length of described oilhole 3 equals the length of valve block.
The case study on implementation of Fig. 1:
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, and piston 2 drives pull bar 4, and valve block 1 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 2 is inhaled, valve block 1 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.
The case study on implementation of Fig. 2:
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 that piston 2 overcomes spring moves right, and lubrication hole is closed by valve block 1;
When the descent of piston of motor, negative pressure in crankcase disappears, piston 2 in spring handle pore pushes up go back to the left side, valve block 1 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, by the to-and-fro motion of the piston of 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.
