Abstract
The present invention provides a one-way rotary valve type internal combustion engine for providing power for motor vehicles, ships and generators. The present invention replaces the camshaft, tappet, push rod, valve rocker assembly, valve assembly, etc. in available internal combustion engine, and has simple structure, less parts, easy machining, reliable operation, high mechanical efficiency, fully increased effective ventilating section of the intake and exhaust valves, reduced gas distributing resistance, less vibration and noise, greatly raised rotation speed and excellent dynamic performance and economic performance.
Description
The present invention relates to a kind of one-way rotary air gate type internal-combustion engine that power is provided for motor vehicle, boats and ships, motor etc.
Flexible air gate type, pore-flexible air gate type are arranged in the I. C engine distribution mechanism at present, also have the plane sliding valve structure in addition.The revolution inertial resistance of plane guiding valve distribution device is big, complex structure, and the parts processed complex is so seldom adopt; Pore formula, pore-flexible valve type distribution device are used on the scavenging type two-stroke internal-combustion engine, and this mechanism makes the parts insufficient lubrication, and wearing and tearing are big, so only adopt on float amount internal-combustion engine; Flexible valve type distribution device will have camshaft, valve spring valve, generally also valve tappet, push rod, rocker arm body etc. to be arranged, and these parts will produce very big reciprocal inertial resistance and surface friction drag when internal combustion engine operation, and overcome the required resistance to compression pression of valve spring etc., account for 10%～20% of internal-combustion engine useful work consumption.The existing common deficiency of distribution device is exactly that combustion chambers of internal combustion engines effective ventilation cross section can not fully be enlarged by structural limitations own, and the gas exchange loss merit is still very big, accounts for about 45% of internal-combustion engine useful work consumption.
The objective of the invention is in order to provide a kind of distribution resistance little, the mechanical efficiency height, vibration is little, noise is low, has the remarkable power character and the one-way rotary air gate type internal-combustion engine of Economy.
(1) cylinder cap, (2) air valve shaft cover, (3) air valve shaft, (4) diaphragm seal, (5) grease baffle, (6) spring among the figure.
Cylinder cap has the valve axis hole on (1), and air valve shaft (3) is horizontal on cylinder cap (1), air valve shaft (3) two ends rolling bearing fixed bearing.Have valve port on air valve shaft (3) cylinder, have the air vent valve port to communicate in the air valve shaft (3) with air vent.The valve port position of going up on the corresponding air valve shaft (3) at cylinder cap (1) also has valve port, directly feeds the firing chamber.Air valve shaft (3) is done unidirectional continuous rotation by crank-driven, constitutes the firing chamber air vent by the overlapping of the valve port on the valve port on the air valve shaft (3) and the cylinder cap (1).Can arrange intake duct and air outlet flue simultaneously on the air valve shaft (3), drive gas port and relief opening into by port timing, end at interval in the inlet and outlet road, the one end air inlet of air valve shaft (3) two ends, the other end exhaust, intake duct and air outlet flue also can be arranged on two air valve shafts, two air valve shafts are arranged in parallel on the cylinder cap (1), diaphragm seal is arranged in cylinder cap (1) valve axis hole inboard around valve port, arrange straight diaphragm seal (4) vertically, arrange that radially the circular arc diaphragm seal is to constitute the airtight zone of sealing.Spring (6) is put in the bottom of sealing film trap, so that diaphragm seal is pressed against on the air valve shaft (3) all the time, guarantees the sealing of firing chamber.Outside the diaphragm seal of Bu Zhiing (4), air valve shaft (3) is gone up valve port and is at first arranged grease baffle (5) in one side of process vertically.Between last grease baffle (5) of cylinder cap (1) and diaphragm seal (4), have oil leab, supply with extreme pressure lubricant by oil pump at interval by control valve, primary lubricant diaphragm seal and air valve shaft (3).At interval the purpose of oil feeding method is to prevent that the valve port that machine oil passes through on the air valve shaft (3) from scurrying into firing chamber and intake and exhaust port.Method is to go up when air valve shaft (3) to stop this oil duct fuel feeding when valve port forwards near grease baffle (5); Hold one's breath and restart this oil leab fuel feeding behind the close zone when valve port changes the sealing that into is made of diaphragm seal.
The present invention has replaced all parts such as present internal-combustion engine convexity wheel shaft, valve tappet, push rod, valve rocker arm assembly and valve assembly with air valve shaft (3), Structure of Internal-Combustion Engine is obviously simplified, manufacture cost reduces, it can fully increase effective ventilation cross section, firing chamber (existing four air valve structures are also not as good as it) what is more important, and air-flow do not have flow-disturbing loss at the valve port place, makes air flue more smooth.Air valve shaft (3) is done unidirectional rotation, does not have reciprocal inertial resistance, and can obtain proper lubrication and cooling.This comprehensive effect of the present invention can make internal-combustion engine obtain more remarkable power character and the Economy of more modern reinforced internal-combustion engine, can also eliminate the distribution noise better, reduces vibration.
The present invention compare with present internal-combustion engine have simple in structure, reliable operation, processing easily, advantage such as the distribution resistance is little, mechanical efficiency is high, vibration is little, noise is low, use is easy to maintenance, make internal-combustion engine have even more ideal power character and Economy.
Realize that best mode of the present invention is the diameter that increases air valve shaft (3) as far as possible, the corresponding ventilation sectional area that has increased valve port.
Claims (1)
- A kind of one-way rotary air gate type internal-combustion engine, it is that the inner air valve shaft (3) that air vent arranged is rotated by the crank-driven continuously-directional, constitutes the firing chamber air vent by the overlapping of the valve port on the valve port opened on the air valve shaft (3) and the cylinder cap (1).Around cylinder cap (1) valve port, arrange diaphragm seal between air valve shaft (3) and the cylinder cap (1), arrange that vertically straight diaphragm seal (4) arranges that radially the circular arc diaphragm seal is to constitute the airtight zone of sealing, spring (6) is put in the bottom of sealing film trap, so that diaphragm seal is pressed against on the air valve shaft (3) all the time, guarantee the sealing of firing chamber, grease baffle (5) is arranged in the diaphragm seal of Bu Zhiing (4) outside vertically, on cylinder cap (1), have oil leab between grease baffle (5) and the contiguous diaphragm seal (4), supply with extreme pressure lubricant by oil pump at interval by control valve, promptly go up valve port and forward near stopping this oil duct fuel feeding during with the regions of lubrication of being close between the diaphragm seal (4) by grease baffle (5) when air valve shaft (3); After valve port turns over regions of lubrication again to this oil duct fuel feeding.
