Abstract

A heat engine employs counterrotating rotors disposed in different cavities of a stator. The engine provides a heat recuperator which removes heat from working medium confined in a rotating constant volume chamber in one cavity and utilizes that heat to heat working medium confined in a rotating constant volume chamber in another cavity. Each rotor carries partitions forming separate chambers in its cavity and each cavity has a blocking means which permits the partitions to pass but prevents working medium from making a complete orbit in the cavity whereby the working medium is caused to flow from one cavity to another through ducts disposed near the blocking means.
