Separately have the motor of the rotary engine (patent No. 01134215.3) of balance, novel structure, but because its rotor air chamber is limited, power is also very limited, and must increase design size to improve.
Whirlpool axle and whirlpool slurry engine power weight ratio greatly, but due to complex structure, involve great expense, and gas channel is Open architecture, causes engine consumption high, is unsuitable for civilian on a large scale.
Summary of the invention
The object of this invention is to provide a kind of structure simple, reliability is high, the motor that volume is little, and it has larger power-weight ratio, good economic usability, lower manufacture cost.
The solution of this motor is as Fig. 1, by housing (1), fuel chamber (2), turbine (3), rotary valve (4), pressurized machine (5) forms, air chamber between the blade of turbine (3) is divided into increase-volume chamber (6) and subtracts cavity volume (7) by rotary valve (4), turbine (3) and housing keep good tightness, rotary valve (4) and housing keep good tightness, also keep good tightness with turbine hub simultaneously; Rotary valve (4) does intermittent movement, and switch by rotating time rotary valve (4) at the blade of turbine (3), all the other time keeps standstill seal.By gear between turbine (3) and rotary valve (4), mechanism's rigidity transmissions such as sheave, ensure the gap between turbine (3) and rotary valve (4), avoid mutual interference.
As improvement of the present invention as Fig. 2, air chamber between the blade of turbine (3) is divided into increase-volume chamber (6) and subtracts cavity volume (7) by flexible valve (8), flexible valve (8) does intermittent movement, turbine (3) blade by time retract, sealing is stretched out in the maintenance of all the other time.By gear between turbine (3) and flexible valve (8), mechanism's rigidity transmissions such as cam, ensure the gap between turbine (3) and flexible valve (8), avoid mutual interference.
As improvement of the present invention as Fig. 3, the interlobate air chamber of turbine (3) is separated into the increase-volume chamber (6) of incomplete sealed type and subtracts cavity volume (7) by worm screw valve (9), the blade of turbine (3) carries out the switching of secret room by the passage between worm screw blade, by the transmission of gear mechanism rigidity between turbine (3) and worm screw valve (9), ensure the gap between turbine (3) and worm screw valve (9), avoid mutual interference.
As popularization of the present invention, fuel chamber (2) connects high-energy gas generator, gas is incorporated into turbine (3) increase-volume chamber (6), gas energy is converted into the moment of torsion of turbine shaft, can be used as turbine effect.
Advantage of the present invention is, structure is simple, and volume is little, and noise is little, and other turbogenerator has superior fuel economy relatively, therefore manufacture cost also relative moderate, can for carrying automobile of the present invention, and boats and ships and aircraft reduce deadweight, save space.
Another advantage of the present invention is, the gas path design of sealed mode, freely volume diffusion, makes its other turbogenerator relative have obviously superior fuel economy.
Another advantage of the present invention is, turbine and housing are contactless structure, and the inordinate wear that also can not cause turbine and housing when occurring overheated crossed by motor, improves service life of aeroengine, reduces maintenance cost.
Another advantage of the present invention is, can use as cell cube multi-stage combination, increases engine power, reduces engine speed, reduces energy loss.

Embodiment
Housing (1) adopts split casting, and the surface coordinated with valve (3) blade and turbine (4) blade adopts the characteristic of relative coarseness, but requires planeness, circularity, and tapering is little.Middle cylinder water-cooling formula design.
Rotary valve (4) can adopt integrated type or split type quaterfoil structure, split typely can reduce later period maintenance cost, and blade tip adopts smooth design, can adopt the sealability promoting valve cage with the contact seal of housing.
Turbine (3) adopts split-type design, and be divided into wheel hub and blade, blade tip adopts smooth design, can install front and back ring packing side plate, can increase the sealability that turbine blade quantity promotes turbine chamber.
As another improved procedure of turbine (3), hub design becomes band supercharging type spoke structure, and Design Turbine Blade is hollow.Inlet air enters in the middle part of turbine by air filter, by the turbine blade of hollow after wheel hub supercharging, from ring packing side plate out, enters increase device by shell channel, enters fuel chamber after further supercharging.
Turbine shaft installs gear, and connected by a timing idle pulley and Geneva mechanism, sheave is arranged on rotary pneumatic door-hinge.Guarantee turbine and the rotary valve coordinated movement of various economic factors, and ensure gap between turbine and rotary valve.
The increase-volume chamber (6) that the high energy combustion body that fuel chamber (2) produces directly enters turbine releases energy, and promotes turbine (3) and rotates, output torque.Gas after releasing energy rotates with turbine air chamber, and under the effect subtracting cavity volume (7), discharge housing (1), remaining energy enters pressurized machine (5), increases suction pressure and enters next circulation.
As another embodiment of the present invention, adopt the flexible air valve structure of Fig. 2, valve minimum number, but valve cage result size is larger.
As another embodiment of the present invention, adopt the worm screw valve result of Fig. 3, the impact that intermittent movement produces can be eliminated, but because increase-volume chamber (6) and subtract cavity volume (7) for non-enclosed structure, efficiency is slightly lower than Fig. 1, Fig. 2 structure.
As another embodiment of the present invention, high energy gas is produced by high-energy fuel gas or steam generator, the increase-volume chamber (6) of access turbine (3), then discharge by subtracting cavity volume (7), enter condenser condensation again, finally enter combustion gas or steam generator and carry out next circulation.
