Abstract

PURPOSE:To absorb precession when a guide plate is driven by a swash plate, by coupling a piston rod with a guide piston in a loose fit engagement, through the intermediary of slide plates having a low frictional coefficient. CONSTITUTION:A piston rod 20 at the lower end of a piston 11 is coupled with a guide piston 31 attached to a rod 14 moved up and down by a swash plate 16, at one end thereof. A piston cover 32 formed therein with a recess 33 is secured to the upper section of the guide piston 31, and a flange section 21 at the lower end of the piston rod 20 is fitted in the recess 33 through the intermediary of slide plates 34, 35 having a low friction coefficient. This coupling section has a sufficient gap, and therefore, precession which is generated when the guide piston 31 is driven by the swash plate is absorbed by the above- mentioned gap.

点を有していた。(Problems to be Solved by the Invention) When the conventional Stirling engine transmits the output from the movable piston 11 to the swinging swash plate 16, the guide piston rod 14 performs not only vertical movement but also precession movement, and as a result of the latter movement, side thrust is applied to movable piston 11 on the driving side. For this purpose, the movable piston 11 is disposed between the outer circumferential surface of the movable piston 11 and the inner circumferential surface of the piston cylinder 10.
This has the problem that a large frictional force is generated due to the side thrust, which causes torque fluctuations and reduces the rotational output of the output shaft 15.
