Abstract

The air pressure engine capable of providing power is disclosed in the invention. The invented engine is produced based on existing gasoline engine and diesel engine with being modified as follows. Top of cylinder is sealed off and the piston is a tight match for the cylinder. The piston is coupled to exterior electron-motor and flywheel through crankshaft and connecting bar. At beginning, the piston is drawn toward outer by the exterior electron-motor, forming vacuum in inner cylinder. With the crankshaft being rotated a half cycle, the piston is pressed toward inner of cylinder by the action of pressure difference produced between inner and outer of the piston, thus proceeding the power stroke. From that time on said circulation is continued. Comparing with prior art technique, the air pressure engine saves more energy and avoids air pollution effectively.

Description

Air motor

The invention relates to a kind of air motor that utilizes atmospheric pressure that power is provided.

At present, petrol engine, the diesel engine that power is provided is to make fuel in the fried burning of cylindrical implosion, outwards promotes the piston acting, causes the dependence of the energy greatly, and the waste gas of burning and exhausting causes certain pollution again.

The invention provides a kind of air motor, and it does not need consume fuel, and non-exhaust emission, and power can effectively be provided.

The purpose of the invention is achieved in that cylinder interior is provided with and closely cooperates with cylinder wall and can pistons reciprocating, the piston lower end links by connecting rod and bent axle, on bent axle, be provided with flywheel, cam and gear, this gear and motor gear interlock, one movable contact is set, with the work of control motor under the cam.Around the aerostatic press cylinder body and in the cylinder cap, be provided with cooling jacket in addition, be provided with oil leab at connecting rod and bent axle inside.In airtight cylinder interior, piston is positioned at top dead center position at first, during startup, coupling motor at first driven gear stretches piston from inside to outside by bent axle, connecting rod, in the process that stretches, form vacuum between piston head and the cylinder, piston is inside and outside because the inconsistent generation pressure difference of atmospheric pressure (this pressure difference can increase with the increase of piston area), when lower dead center is arrived in piston motion, motor quits work, at this moment, piston can be pushed back rapidly under the effect of external and internal pressure difference, forms acting.Afterwards, motor is activated again, and the flywheel acting in conjunction with high speed rotating is drawn out piston once more, and when treating to be stretched to lower dead center once more, piston is pushed back by atmospheric pressure again, forms circulation, and power is provided.

Adopt such scheme, can utilize the inside and outside pressure difference that produces of atmosphere to obtain power, reduce energy consumption, there is no pollution of atmosphere.

Below in conjunction with drawings and Examples the invention is described further:

Fig. 1 is the invention structural representation;

Fig. 2 is a drawing stroke principle schematic representation;

Fig. 3 is the expansion stroke principle schematic;

Among the figure: 1, cylinder 2, piston 3, connecting rod 4, bent axle

5, flywheel 6, coupling motor 7, cam

8, movable contact 9, gear 10, stationary contact

Among Fig. 1, be provided with in cylinder (1) inside and closely cooperate with cylinder wall and can pistons reciprocating (2), the piston lower end links by connecting rod (3) and bent axle (4), be provided with flywheel (5) at bent axle one end, piston this moment (2) is positioned at top dead center position, cam (7) is depressed movable contact (8), contact stationary contact (10) is connected circuit, motor work, driven gear (9) rotates, by bent axle (4) piston (2) is stretched from inside to outside, when piston was stretched to lower dead center, cam (7) left movable contact (8) again, motor (6) quits work, and piston (2) is pushed back acting.

Outwards stretched gradually under piston among Fig. 2 (2) drive of live motivation (6) outside, make between piston (2) upper end and cylinder (1) top and form vacuum, in the process that piston (2) is stretched gradually, piston (2) lower end is subjected to the pressure of atmosphere, and piston (2) upper end forms vacuum, at this moment, can be at a pair of unbalanced force that produces by barometric pressure of appearance at two ends up and down of piston (2), resultant direction is pointed to cylinder interior.

Piston among Fig. 3 (2) is when turning over lower dead center, and motor (6) quits work, and at this moment, piston (2) produces under the action of pressure and can be pressed into cylinder interior rapidly at inside and outside atmosphere, finishes expansion stroke, and power is provided.Afterwards, motor (6) can be restarted, and with the flywheel acting in conjunction of high speed rotating, once more piston is pulled out, and forms circulation, and power is provided.
