Description

Rotary one-stroke motor

The utility model relates to a kind of motor, specifically is rotary one-stroke motor.

In 1876, German's Otto was invented the four-journey petrol engine, all was the piston circuit of finishing the work that does reciprocating linear motion in cylinder as two stroke gasoline machines, and people often are referred to as reciprocating-piston engine.This motor is when piston motion, and the size and Orientation of its speed is all becoming.Changing two dead-centre positions of direction, its speed reduces to zero, and produces huge inertial force, a fatal weakness that can't overcome of Here it is Reciprocating engine.In 1 or nine the May 4th years, West Germany's engineer's wankel has been invented rotary engine, uses the rotor instead of piston, has realized with the replacement to-and-fro motion that rotatablely moves.The work done face of Wankel engine is to rely on torque difference to finish power output, still, because torque difference is very little, so the oil consumption of this motor is quite high.

The purpose of this utility model just provides a kind of rotary one-stroke motor, has both overcome the high weakness of Wankel engine oil consumption, has brought into play rotary engine rotating speed height again, vibrate little, the advantage of compact structure.

The technical solution of the utility model is: comprise body, spark plug, work done part and supercharging part, work done partly comprises rotor and composite rotors, both pass through 1: 1 gear engagement, the supercharging part also comprises rotor and composite rotors, the composite rotors of supercharging part is contained on the same axle of work done rotor partly, the same axle that the rotor of supercharging part is contained in the composite rotors of work done part is gone up and is meshing with each other, wherein the rotor of work done part and supercharging part is cam structure, and design has the distribution valve block, composite rotors is recessed the wheel, groove on it with and the cam of its engagement and on the distribution valve block match, have gas storage chamber in the body, have on the gas storage chamber with the partially communicating compressed mixed gas of supercharging inlet and with the partially communicating compressed mixed gas outlet of work done.

According to technique scheme, the rotor of supercharging part of the present utility model is to be used for sucking mixed gas and while compressed mixed gas, groove on the composite rotors then be used for holding rotor projection and on the distribution valve block, to guarantee rotor and the tight engagement of composite rotors in rotary course.Gas after the compression enters gas storage chamber by compressed mixed gas inlet.The rotor of work done part then is to be expanded through the spark ignitor after-combustion by the pressurized gas that the compressed mixed gas from gas storage chamber exports out to promote work done, and simultaneously waste gas is discharged, groove on the composite rotors be equally be used for holding epitrochanterian projection and on the distribution valve block, to guarantee rotor and the tight engagement of composite rotors in rotary course, the distribution valve block of the distribution valve block of work done part and supercharging part is to be used for regularly start or stop compressed mixed gas outlet and compressed mixed gas inlet respectively, to guarantee the proper functioning of motor.

Therefore, it is the rotor rotary structure that the rotary one-stroke motor that the utility model provides is changed the conventional reciprocating piston cylinder operator, thereby overcome the conventional engine inefficiency, defectives such as energy consumption height, have rotary engine rotating speed height, the vibration little, the characteristics of compact structure, and it is low to have an oil consumption, energy-saving advantages.

Below in conjunction with embodiment's accompanying drawing the utility model is described in detail.

At first to description of drawings:

Fig. 1 represents three-dimensional cutaway view of the present utility model, is the embodiment of two group rotor formula motors;

Fig. 2, Fig. 3 represent that respectively the distribution valve block of work done part opens the outlet of compressed mixed gas, the distribution valve block of the supercharging part closing state that just pressurized gas entered the mouth;

Fig. 4, Fig. 5 represent the rotor of work done part respectively just at work done and combustion gas, and the rotor of supercharging part is at the state that sucks mixed gas and compress simultaneously;

Fig. 6, Fig. 7 represent that respectively the rotor work done of work done part finishes, and the distribution valve block is about to compressed mixed gas port closing and the distribution valve block of supercharging part is about to the state that compressed mixed gas inlet is opened;

Fig. 8, Fig. 9 represent that respectively the distribution valve block of work done part opens the outlet of compressed mixed gas, and rotor begins work done, and the rotor compression of supercharging part finishes, and the distribution valve block is with compressed mixed gas inlet closing state.

Referring to Fig. 1, the utility model comprises body 14, spark plug 3 and work done part and supercharging part, work done partly comprises rotor 1 and composite rotors 2, both mesh by 1: 1 gear 13, the supercharging part also comprises composite rotors 7 and rotor 8, composite rotors 7 is contained on the same axle of work done rotor 1 partly, rotor 8 is contained on the same axle of work done composite rotors 2 partly, and be meshing with each other, rotor 1 and rotor 8 are cam structure, and design has distribution valve block 4,9, composite rotors 2 and 7 is recessed the wheel, groove 6 on it, 10 with and the cam of its engagement and on distribution valve block 4,9 match, and have gas storage chamber 12 in the body 14, have on the gas storage chamber 12 with the partially communicating compressed mixed gas inlet 11 of supercharging with the partially communicating compressed mixed gas of work done and export 5.

Its design principle and working procedure are: drive work done rotor 1 and composite rotors 2 rotations partly by a pair of 1: 1 gear 13, the composite rotors 7 of supercharging part and rotor 8 produce synchronously and rotate.When the distribution valve block 9 closes compression mixed gass inlet 11 that increases part, the distribution valve block 4 of work done part is opened mixed gas outlet 5, shown in Fig. 2,3.Rotation along with rotor 8, the a-quadrant sucks fuel mixture, B zone compression fuel mixture, as shown in Figure 5, fuel mixture after the compression enters gas storage chamber 12, compressed then mixed gas outlet 5 comes out to enter the C zone, spark plug 3 igniting, burning expansion, promote the rotor 1 inhour rotation work done of work done part, simultaneously surplus waste gas is discharged from the D zone, as shown in Figure 4, rotation along with work done part rotor 1, distribution valve block 4 is with closes compression mixed gas outlet 5, and Fig. 6 is for being about to closing state, and 9 of the distribution valve blocks of supercharging part will be opened compressed mixed gas inlet 11, the state of Fig. 7 for being about to open, this moment, the fuel mixture compression in B zone entered gas storage chamber 12 by mixed gas inlet 11.Along with the rotation of rotor, in the supercharging part, rotor 8 compressions finish, distribution valve block 9 closes compression mixed gass inlet 11, see Fig. 9,4 of the distribution valve blocks of work done part are opened mixed gas outlet 5, see Fig. 8, compressed mixed gas comes out to be lighted by spark plug 3, C zone expansion working, D zone exhaust waste gas.Enter next circulation thus.

Rotor 1 whenever rotates a circle work done once, and (G is (between 270 °, like this about 180 ° greatly in the work done zone, for single rotor promptly two concerning the motor of a group rotor, there is the non-work done zone of nearly 90 ° of scopes, makes engine running more steady, more powerful, can adopt double rotor is that two pairs two group rotors or many rotors are the structure of group rotor formula more than two pairs, and every group rotor angle that staggers mutually makes rotor in rotary course, and motor is being worked always, and power is big, and running steadily.That shown in Figure 1 is the embodiment of birotary engine.
