Description

Compressed air engine

Technical field

The utility model relates to a kind of compressed air engine, belongs to technical field of engines.

Background technique

Known motor need be a power with fuel, and fuel produces toxic emission in atmosphere after work done is finished, and environment is polluted, and As time goes on, fuel can be more and more nervous, and how to address this problem has become the emphasis of countries in the world problem; Its complex structure of existing air engine, the manufacture cost height, it is big to control difficulty.

Summary of the invention

In order to overcome above-mentioned technical problem, the utility model provides a kind of compressed air engine, and this compressed air engine is pollution-free, without fuel, and is simple in structure, controls easily.

The technological scheme that its technical problem that solves the utility model adopts is: the cylinder head middle part is provided with inlet hole and exhaust port, cylinder head is provided with intake valve and exhaust valve in the middle of the middle part, gear on the bent axle is meshed with gear on the camshaft, it is the 80-90 degree that every group of cam installed angle, bent axle connects the piston in the cylinder body, pressurized gas enters cylinder body and impels piston to move reciprocatingly, and cam is made symmetrical rhombus or ellipse, and cam makes intake valve or exhaust valve close or open by the valve rocker on the tappet;

Its concrete scheme is: be respectively equipped with intake valve, exhaust valve in the middle of the cylinder head of cylinder body upper end, be provided with inlet hole, be provided with exhaust port with the corresponding position of intake valve with the corresponding position of exhaust valve, piston in the cylinder body connects bent axle by connecting rod, crankshaft gear is installed on the bent axle, cam wheel and crankshaft gear engagement are installed on the camshaft, be installed into valve cam, exhaust valve cam on the camshaft, inlet valve cam and tappet are slidingly connected, exhaust valve cam and another tappet are slidingly connected, tappet connects valve rocker, and valve rocker is pushed down valve stem; Gas tank is provided with valve, and valve connects accelerator by gas pipeline, flange plate, and accelerator connects inlet hole by suction tude;

Its working procedure is: turning crankshaft drives piston, intake valve is opened pressurized gas and is entered cylinder body, the promotion piston moves reciprocatingly, and piston runs to lower dead center, and cam is closed intake valve by tappet, valve rocker, open exhaust valve and discharge gas, piston is got back to top dead center, and at this moment, the closed intake valve of exhaust valve is opened, finish an operation cycle, repeat above-mentioned motion motor continuous operation; The rotating speed of accelerator control motor increases tolerance and quickens, and reduces tolerance and slows down, and closes tolerance and stops operating;

This motor can be provided with single cylinder or multi-cylinder, can decide what of cylinder body according to watt level is set.

The beneficial effects of the utility model are: do not burn in the engine working process, do not produce heat and waste gas, start easily, speed governing is fast, and is pollution-free.
