    • 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.
    • 用于斯特林型发动机的加热器头组件具有圆筒和再生器壳体,每个都包括作为其整体部分的歧管,并且加热器管一端插入气缸歧管中,另一端插入再生器壳体歧管 连接气缸和再生器壳体。 每个歧管在加热器管侧上纵向变宽,使得由其内壁限定的工作气体流动通道的纵向宽度大于相应的气缸或再生器壳体的内径。 每个歧管的内壁从加热器管侧的歧管的较宽部分到较窄的相应气缸或再生器壳体的内壁平滑,逐渐和连续地过渡,而不会在工作气体流动通道中形成突然的收缩。
