HARMONIC STEP ENGINE Russian patent published in 2012 - IPC F01B1/06 F15B15/06 F02B75/22 

FIELD: engines and pumps.

SUBSTANCE: invention relates to machine building. Proposed engine consists of toothing between fixed flexible wheel and rotary stiff wheel with output shaft and air (gas) hydraulic straining member. Said air (gas) hydraulic straining member is composed of two aligned discs fitted one into another to allow rotation of inner disc. Sais inner disc comprises N (N=6; 10; 14; 18; 22; 26; 30; 34, etc) radial high-pressure channels and N blind low-pressure interchannel cavities. Fixed outer disc has M (M=8; 12; 16; 24; 28; 32; 36, etc) radial channels for push plungers. Working substance is fed under push plungers in rotation of inner disc from its HP channels. Said push plungers fed the train of power radial pulses to flexible wheel. Note here that ω_w=ω_wheel *H/2, where ω_w is angular speed of flexible wheel straining wave, ω_wheel is angular speed of inner moving wheel at N≠M. Sizes of said discs are selected to make two to four adjacent and opposite plungers staying in working position to provided for symmetric deformation of flexible disc oval shape. N and M share single common multiple equal to 2. Given extra fuel feed system said engine makes a harmonic step ICE.

EFFECT: higher speed of flexible wheel deformation wave rotation.
