Roterande förbränningsmotor och hydraulmotor

摘要

A rotary engine and a hydraulic motor including non-rotary outer and inner casings; a power shaft with an eccentric part; a driving eccentric ring between the outer and inner casings and mounted on the eccentric part; a combustion or pressure chamber between the eccentric ring and the inner casing such that the eccentric ring drives the power shaft by substantially non-rotating eccentric movement; dividers for dividing the combustion chamber into at least two parts, the dividers extend through the inner casing and are in contact with an inner surface of the driving eccentric ring; and an eccentric device (or control) for driving the dividers back and forth with respect to the inner casing. The eccentricity of the eccentric device corresponds with the eccentricity of the eccentric part of the power shaft. The eccentric device has a guide groove which implements an eccentric path and to which the dividers are connected.
