Abstract
The utility model relates to a rotating valve air intake and exhaust mechanism of a pneumatic automobile engine, which mainly comprises a cylinder end, a rotating intake valve and a rotating exhaust valve. The working media of a pneumatic automobile engine is simple air and nitrogen gas, so that not only real zero discharge can be realized, but also urban air can be purified. Compared with other 'zero discharge' power, such as cell engines and fuel cell engines, the utility model has more conspicuous protective effects on the urban atmospheric environment; compared with traditional air intake and exhaust mechanisms for internal combustion engines, the rotating valve air intake and exhaust mechanism has the advantages of simple structure, small noise, convenient coupling adjustment for exhaust phases, small mechanical loss, etc.
Description
Technical field
The utility model relates to air powered engine rotating valve intake and exhaust mechanism.
Background technique
Vehicle exhaust is the main reason of urban air pollution, and the greenhouse gases of its discharging account for the proportion maximum of global human emission greenhouse gas gross.The working medium of air motor is simple air or nitrogen, so can realize zero-emission truly, is developing direction.At present, reciprocating air engine still adopts traditional combustion engine push rod valve intake and exhaust mechanism, and its deficiency is: 1) noise is bigger.2) internal-combustion engine is a natural aspiration, and traditional push rod valve mechanism is by cam drive, in case cam-shaped line determines that valve maximum opening and phase place fit angle are also determined thereupon.And the air motor air inlet requires pressure and flow can regulate, promptly requires air inlet phase adjustable.So traditional push rod valve intake and exhaust mechanism can not satisfy the requirement of air motor.
Summary of the invention
The purpose of this utility model provides a kind of air powered engine rotating valve intake and exhaust mechanism.To adapt to the specific (special) requirements of air motor work.
Air powered engine rotating valve intake and exhaust of the present utility model mechanism mainly comprises cylinder head, rotation suction valve and rotating exhaust valve.Have two in the cylinder head with the cylindrical hole of parallel axes and respectively with the cylindrical hole quadrature and through the gas-entered passageway and the exhaust passage of cylinder head.Rotation suction valve and rotating exhaust valve serve as to support to lay respectively in two cylindrical holes with device at the bearing of cylinder head.Rotation suction valve and rotating exhaust valve inlet hole and exhaust port radially arranged respectively, corresponding with the gas-entered passageway and the exhaust passage of cylinder head.The outer wall of rotation suction valve and rotating exhaust valve have be located at cylinder head in the asphalt channel longitudinal groove and the circumferential grooves that are communicated with, one end of rotation suction valve and rotating exhaust valve is by the end bracket enclosed that is fixed on cylinder head, the other end respectively is fixed with gear, these two gears are meshing with each other, wherein at a rotary valve end device flange, the sprocket wheel that flange is connected with live axle links to each other.
Air powered engine rotating valve intake and exhaust of the present utility model mechanism has the following advantages:
1) admission gear's noise is little.
2) compact structure is simple.
3) intake and exhaust phase place cooperates and can arbitrarily angledly adjust.
4) mechanical loss is little.

Fig. 4 is the phase place cooperation figure of air motor intake and exhaust mechanism.
Embodiment
With reference to Fig. 1, Fig. 2, air powered engine rotating valve intake and exhaust mechanism mainly comprises cylinder head 7, rotation suction valve 5 and rotating exhaust valve 3.Have two in the cylinder head with the cylindrical hole of parallel axes and respectively with the cylindrical hole quadrature and through the gas-entered passageway 21 and the exhaust passage 22 of cylinder head, rotation suction valve 5 and rotating exhaust valve 3 serve as to support to lay respectively in two cylindrical holes with device at the bearing 13 of cylinder head, at rotation suction valve 5 and rotating exhaust valve 3 inlet hole 8 and exhaust port 4 arranged respectively radially, corresponding with the gas-entered passageway 21 and the exhaust passage 22 of cylinder head, when inlet hole 8 is opened gas-entered passageway 21, exhaust port 4 is closed exhaust passage 22, otherwise when exhaust port 8 was opened exhaust passage 21, inlet hole 4 was closed gas-entered passageway 22.In order to reduce the pivoting friction resistance of rotation suction valve 5 and rotating exhaust valve 3, outer wall at rotation suction valve 5 and rotating exhaust valve 3 has longitudinal groove 9 and circumferential grooves 10, longitudinal groove 9 and circumferential grooves 10 are communicated with asphalt channel 2 in being located at cylinder head, the engine oil passage feeder connection 1 of cylinder head links to each other with asphalt channel 2, like this, can enter longitudinal groove 9 and circumferential grooves 10 by asphalt channel 2 machine oil, thereby make rotary valve lubricated good.Oil sealing 11 and the end cap 6 that is fixed on cylinder head one end can prevent the side leakage of machine oil.The other end at rotation suction valve 5 and rotating exhaust valve 3 respectively is fixed with gear 15 and 20, and these two gears are meshing with each other, and wherein at a rotary valve end device flange 18, the sprocket wheel 16 that flange is connected with live axle links to each other.In order to realize that air inlet begins the fine setting of angle, several waist shaped hole 17 (see figure 3)s are set on sprocket wheel usually, sprocket wheel links to each other by the fine adjustment screw 19 that passes through waist shaped hole with flange.
During the air motor operation, the pressurized air of high pressure or nitrogen promote piston, and piston promotes bent axle by crank and drives the rotating shaft rotation, the rotation of rotating shaft driving sprocket wheel.With reference to Fig. 4, engine piston runs to θ behind the top dead center A
0Crank angle, the inlet hole of air inlet rotary valve is opened the cylinder head gas-entered passageway, and air inlet begins.When intake process has continued 4 α crank angles, i.e. the clockwise angle that the C point is ordered to D among the figure, the inlet hole of air inlet rotary valve is closed the cylinder head gas-entered passageway, and intake process finishes.Subsequently, the gas in the jar acting of further expanding.When piston ran to the lower dead center B left and right sides, the exhaust port of exhaust rotary valve was opened the cylinder head exhaust passage, and exhaust begins.When intake process has continued 4 β crank angles, i.e. the clockwise angle of ordering to C from the E point among the figure.During crank angle, the vent closure cylinder head exhaust passage of exhaust rotary valve, exhaust process finishes, and and then intake process restarts.Thus, by this cycle operation of rotating valve intake and exhaust mechanism, realized air inlet, the exhaust process of air motor.
The angle that air inlet begins can be adjusted by the meshing relation of two gears 15 and 20 with the cooperating of angle that exhaust begins.By adjusting fine adjustment screw, sprocket wheel can be done clockwise or counterclockwise moving with respect to flange, realizes the fine setting of air inlet retardation angle.
