Abstract:
This is a project of mechanical machine, which allowed smoothly change rpm ratio between input and output with principle of conservation of energy (no loss of power) while changing the ratio.

Description:
BACKGROUND OF THE INVENTION 
     This invention relates to the new and improved automatic transmission. The constant problem to create better transmission which allows for better matching between input rpm and output rpm and smoothly changing ratio between rpm&#39;s was addressed by many inventors with better or worse results. Most of these designs allow smoothly rpm change with significant power loss. In this design, I am trying to show the other solution with virtually no power loss. The only power loss will come out of imperfections of building moving parts and it could be in range of 1%. 
     DESCRIPTION OF PRIOR ART 
     Many mechanical machines are powered by, motors or engines and it was always problem of matching rpm&#39;s. In motor vehicles for example to do that task, transmission are used. These transmissions can not match perfectly engine to wheels due to the limited amount of gears they contain. There was always need to create an automatic transmission which allows smoothly change ratio between rpm&#39;s with no power loss. 
     This design try to solve this problem and allows smoothly change rpm&#39;s between input and output with no power loss. 
     OBJECT AND ADVANTAGES 
     Accordingly, two advantages of my invention are: 
     (a) To provide almost perfect match between engine and wheels. 
     (b) To provide cost saving production due to simplicity of design. 
     SUMMARY 
     In accordance with the present invention described here, torque converter comprise of housing divided into two chambers by divider  4 , two independent rotors ( 2  and  5 ) and two seals ( 3  and  6 ) preventing liquid getting out of housing.

     DETAILED DESCRIPTION 
       FIG. 2  shows the whole assembly of this unit with removed housing and contains:  1 —body of the pump which is normally located between part  3  and part  6  (here removed for the reason to show how internal parts are aligned).  4 —divider, which divide body  1  into two chambers or two pumps.  2 —rotor of first pump,  5 —rotor of second pump.  3  and  6 —are two closing walls to prevent liquid escape from inside body  1 . 
       FIG. 3  is a side view of assembly.  FIG. 3A  is a view A and  FIG. 3B  is a closer view A with part  6  removed to demonstrate location of shaft S of rotor  5  compare to the axle C of body  1 . 
       FIG. 4  is a cross section of the whole assembly in  FIG. 3 . Chambers A and B have the same volume. 
       FIG. 5  is a cross section of the whole assembly in  FIG. 3  with body  1  shifted to the left. Chamber A has increased volume and chamber B has decreased volume. 
       FIG. 5A  shows direction in which shaft S will run around axle C. 
       FIG. 6  is a cross section of the whole assembly in  FIG. 3  with body  1  shifted to the right. Chamber A has decreased volume and chamber B has increased volume. 
       FIG. 6A  shows direction in which shaft S will run around axle C. 
     ADVANTAGES 
     From description above a great advantage—the simplicity of my converter become evident. 
     OPERATION 
       FIG. 4  shows operation of my device. Lets assume that rotor  2  is connected to the engine and is turning with certain speed and divider  4  is located in the center of body  1 , so volumes A and B are equal in size. Pump A (rotor  2 ) and pump B (rotor  5 ) are connected the way that all volume of liquid from chamber A is pumped to pump B and from pump B comes back to the pump A. If rotor  2  is turning with certain speed, then rotor  5  is turning with the same speed and location of shaft S compared to C is unchanged. 
     In  FIG. 5  body was shifted to the left, so chamber A increased volume and chamber B decreased volume. In this case pump A is pumping much more liquid, so rotor  5  of pump B must increase speed compare to rotor  2 . The increased speed of rotor  5  will force shaft S of rotor  5  to run around axle C over dotted line as  FIG. 5A  shows. 
     In  FIG. 6 , the body was shifted to the right, so rotor  5  will decrease speed compare to rotor  2 , because much less liquid is pumped. In this case  FIG. 6A  shows the exactly opposite direction of movement of S around C. 
     CONCLUSION, RAMIFICATION AND SCOPE 
     Thus the reader will see that my method of torque converter provides much better matching engine—wheels connection. 
     While my above description contains many specificities, these should not be construed as limitation on the scope of the invention, but rather as an exemplification of one preferred embodiment thereof. Many other variations are possible. For example, instead two pumps with common body, two pumps with common shaft and separate bodies could be used and output speed could be collected as differential speed between bodies of pumps. 
     Accordingly, the scope of the invention should be determinated not by embodiments illustrated, but by the appended claims and they legal equivalents.
