Claims (5)

1. Motor som omfattar en regulator för kompressionstrycket i motom och som i riktning Mn motoms kolv mot en vevsläng uppvisar en vevstake (2) som har lagrats i ett excenterhjul (3), vilket excenterhjul (3) uppvisar en kuggning centrerad i förhällande till vevslängen, och excenterhjulet drivs av ett reglerhjul (4), kännetecknad av att excenterhjulet (3) och reglerhjulet (4) är sä dimensionerade att radien (R) för vevslängen + rullningsradien (rv) för kuggkransen pä excenterhjulet (3) = rullningsradien (Rs) för reglerhjulet (4), som är = 2,5 * rv, varvid beräkningsformeln är Rs = R + rv = 2,5 * rv.
2. Motor enligt patentkrav 1, kännetecknad av att en regleranordning (19) med hjälp av en skjutarm (20) och en vridarm (22) justerar reglerhjulet (4) tili ett önskat läge.
3. Motor enligt patentkrav 1, kännetecknad av att vridarmen har fasts pä en regleraxel (18). När axeln (18) vrids vrider den reglerhjulet för varje cylinder.
4. Motor enligt patentkrav 1, kännetecknad av att reglerhjulet (4) för vaije cylinder uppvisar en vridansats (24) och en stötdämpare (29) för att dämpa stötar.
5. Motor enligt patentkrav 1, kännetecknad av att regleranordningen (19) mäter cylindems fyllnadsgrad, drifishastighet och effektbehov. Regleranordningen (19) ändrar kompressionsförhällandet pä sä sätt att ett optimalt kompressionstryck skapas i cylindem.
