Abstract
The utility model discloses a kind of single screw-rod engines, it uses a single screw compressor as air compressor, uses another single-screw machine as expanding machine；It is provided with nozzle opening on told compressor housing, spark plug is housed on told expanding machine shell；In addition to this, told compressor is identical with the other structures of told expanding machine.In told compressor, air sprays into fuel oil when being compressed, gasification of fuel oil heat absorption, reduce compressed air temperature, it is attached on screw rod and star-wheel tooth simultaneously and plays sealing function, the temperature of fuel oil is also improved, the fuel air mixture of high pressure-temperature enters compressor discharge chamber, then pass through the high pressure chest of union He told expanding machine, into the closed chamber being made of screw channel, shell and star-wheel tooth, after told closed chamber is detached from the entrance of told expanding machine, told fuel air mixture is easily ignited by the spark plug, and becomes temperature higher pressure also higher gas；Also higher gas rotates told temperature higher pressure in told closed intraluminal inflation, lead-screw, output power.
Description
Technical field
The present invention relates to engines, specially a kind of to be made of 1 single-screw air compressor and 1 single-screw expander
Engine.
Background technique
The engine being commonly used is reciprocating-piston, and structure is complicated for it, and number of parts is more, poor reliability；Work
There is high temperature exhaust gas in cylinder in the process, reduces the volumetric efficiency of machine；The kinetic energy of the components such as piston and connecting rod cannot benefit
With；The power such as inertia system is unable to complete equipilibrium, and machine vibration is big；Revolving speed is low, and discharge frequency is low, and noise is big.
Wankel engine does not have these disadvantages of conventional engine, but its low speed runnability is poor, close
Envelope will be replaced.
Summary of the invention
The present invention is to provide for a kind of no vulnerable part, can long-term efficient operation single screw-rod engine.
The technical scheme adopted by the invention is as follows: a kind of single screw-rod engine, it uses 2 special single-screw machines as sky
Air compressor and expanding machine；The difference of told air compressor and told expanding machine is: opening on told air compressor shell
There is nozzle opening, and spark plug is housed on told expanding machine shell；The shell of told air compressor and told expanding machine, screw rod
It is identical with the structure of star-wheel.
The special single-screw machine stress balance on told engine is good, and capacity is big, compact-sized volume
Small, no clearance volume, volumetric efficiency is high, small, the no abrasion of the low vibration of noise.
Scheme 1: told air compressor and told expanding machine are contrary on same axis.
Scheme 2: told air compressor and the equidirectional installation of told expanding machine, the back side is connected with 1 pair of meshed gears.
Detailed description of the invention:
Fig. 1-4 is the structural schematic diagram of the embodiment of the present invention one.Fig. 1 is main view, and Fig. 2 is upper view perspective view, Fig. 3 and figure
4 be the partial cross sectional views of Fig. 2.
Fig. 5 is the structural schematic diagram of the embodiment of the present invention two.
Specific embodiment:
Below in conjunction with attached drawing 1-4, present invention is further described in detail.
Embodiment one
As shown in Figure 1, in the present embodiment, when axis is rotated by diagram direction (counterclockwise in face of the extension end of axis), air
The screw channel being made of star-wheel 3 and screw rod 5 and shell 4 is entered by the air inlet 8 of compressor 2；It continues to rotate, entire screw channel is full of
Air is simultaneously closed, and closing screw channel volume becomes smaller, and fuel oil is sprayed into from nozzle opening 11 while air therein is by compression, is generated
Fuel air mixture be discharged by gas vent 12, by the import 14 of the outlet 9 of high pressure chest, connecting tube 10 and expanding machine 1, into
The screw channel for entering the small volume of expanding machine 2 being closed, is then lighted by spark plug 13, becomes high temperature and high pressure gas, pushes
Axis 6 rotates, output power, and the exhaust gas after acting completes 1 circulation by the discharge of outlet 7 of expanding machine.
Embodiment two
As shown in figure 5, in the present embodiment, when axis is rotated by diagram direction (counterclockwise in face of the extension end of axis), air
The screw channel being made of star-wheel 3 and screw rod 5 and shell 4 is entered by the air inlet 8 of compressor 2, is continued to rotate, entire screw channel is full of
Air is simultaneously closed, and closing screw channel volume becomes smaller, and fuel oil is sprayed into from nozzle opening 11 while air therein is by compression, is generated
Fuel air mixture be discharged by gas vent 12, by the import 14 of the outlet 9 of high pressure chest, connecting tube 10 and expanding machine 1, into
The screw channel for entering the small volume of expanding machine 2 being closed, is then lighted by spark plug 13, becomes high temperature and high pressure gas, pushes
Axis 6 rotates；Gear 15 on axis 6 drives compressor 2, while output power through the gear 14 on compressor 2, does
Exhaust gas after function completes 1 circulation by the discharge of outlet 7 of expanding machine.
