PURPOSE:To reduce size of engine while to improve efficiency by realizing optimal volume change and motion of operating fluid of a Sterling engine through a simple and small mechanism comprising a rolling ball and guide groove. CONSTITUTION:Plural phases of sinusoidal guide grooves 3 having circumferential angle as phase angle and axial displacement as amplitude are provided in the outside cylinder face of a rotary shaft 1 which will not displace in axial direction then a plurality of rolling balls 5 held rotatably on the inside face of output piston 4 restricted of rotation are placed in each groove 3 to reciprocate the output piston 4 axially and periodically with rotation of rotary shaft 1. While a plurality of rotatable rolling balls 12 are held on the inside cylindrical face of said shaft 1 then placed in a plurality of sinusoidal guide grooves 11 provided in the outside cylindrical face of a displacer shaft 10 which is reciprocated axially in accordance to the rotation of rotary shaft 1. |
