Rotary Stirling engine

Patent ·
OSTI ID:7336953
A rotary Stirling cycle engine is described. The rotors are utilized as internal heat exchangers and the displacers are utilized as heat regenerators. This engine in its simple configuration consists of two wedge-shaped spherical sectors connected by a disk-like universal type coupling within a spherical housing to form four variable displacement chambers. The sectors which contain passageways for conducting fluids through them are mounted as rotors on rotatable hollow shafts and are covered with fins to provide for the rapid transfer of heat between the conducted fluids and a working fluid contained within the chambers. The coupling which is also covered with fins to complement the rotors in the transfer of heat, contains passageways to interconnect the chambers into two pair and is constructed of porous heat absorbing material to transfer heat to and from the working fluid as it displaces the fluid from one interconnected chamber to the other.
