ABSTRACT:
A heater head assembly for a Stirling-type engine has a cylinder and a regenerator housing each of which includes a manifold as an integral part thereof, and heater tubes inserted at one end into the cylinder manifold and at the other end into the regenerator housing manifold linking the cylinder and regenerator housing. Each manifold is broadened longitudinally on the heater tube side so that a working gas flow passage defined by the inner wall thereof has a longitudinal width greater than the inner diameter of the corresponding cylinder or regenerator housing. The inner wall of each manifold makes a smooth, gradual and successive transition from the broader portion of the manifold on the heater tube side to the inner wall of the narrower corresponding cylinder or regenerator housing without forming a sudden constriction in the working gas flow passage.
