Description

The small size gas turbine that has inlet and exhaust valve and freewheel

One, technical field

The utility model relates to gas engine, especially a kind of small size gas turbine that has inlet and exhaust valve and freewheel.

Two, background technique

At present, the internal-combustion engine formed by bent axle, connecting rod, piston and cylinder of known vehicular engine structure.Fuel-air mixture is sucked cylinder internal, by spark plug it is lighted, explodes again, the impact force of generation promotes piston, thereby through two or four external output mechanical energies of operation cycle that working procedure forms.This process can change mechanical energy into interior, and this principle just begins to use from Steam Engine Age.But there are some inherent defects in it: (1) complex structure, and it is serious, easy to wear to rub between each parts, the rate of fault height, working life is short.(2) utilization ratio to fuel is low.(3) weight and volume is bigger.(4) can not automatic speed-changing and torque-converting, need install gearbox additional.(5) incombustible pluralities of fuel, bad adaptability.

Three, summary of the invention

In order to improve the above shortcoming of existing internal-combustion piston engine, the purpose of this utility model provides a kind of small size gas turbine that has inlet and exhaust valve and freewheel.

The technological scheme that the purpose of this utility model adopted is, include magneto casing and be welded with the supercharging blade, be connected with spline between central shaft and the mixed flow fan, magneto casing and mixed flow fan are welded to connect, after central shaft passes the cylinder case axis, be connected with spline between the single-stage cumulative blade, the central shaft outer shaft sleeve has output shaft, be welded with parallel groove on the dividing plate plate of its cylinder casing front end, in the groove valve is housed between two chutes, there is spring one end on valve two shoulder tops, the spring the other end is welded on the stigmal plate, and the valve top heads on cam, and spline is connected between cam and the central shaft, combuster in the cylinder casing shell, there is exhaust valve the rear end, on the exhaust door-plate relief opening is arranged, be connected with the central shaft spline, the single-stage cumulative blade of distortion is connected with the central shaft spline, be welded with the multistage cumulative vane group of distortion on the output shaft axle, cylinder casing two inclined hole internal threads respectively with the spark plug outside thread, the engagement of oil nozzle outside thread.

The utility model, it is indoor that ignition section of spark plug inserts the firing chamber.

The utility model, it is indoor that the oil nozzle ejiction opening inserts the firing chamber.

Working procedure of the present utility model, the rotation of mixed flow fan and supercharging blade, play water conservancy diversion and pressurized air effect, make air enter the firing chamber from suction port, spray bar sprays into fuel oil detonation under the plug ignition effect, and detonation gas is gone out from relief opening, goes out gas and promotes single-stage cumulative blade and the rotation of multistage cumulative vane group, thereby single-stage cumulative blade drives the mixed flow fan rotation, and multistage cumulative vane group drives the output shaft rotation.

The utility model: (1) has simple in structure, and friction is lacked between each parts, and the advantage that rate of fault is low can increase the service life greatly; (2), can reach 2-3 times of ordinary internal combustion engine to the utilization ratio height of fuel; (3) can realize automatic speed-changing and torque-converting, not need gearbox, thereby greatly reduce weight and volume; (4) incendivity pluralities of fuel is as gasoline, kerosene, diesel oil, alcohol, combustion gas etc.; (5) production technology is simple.
