PURPOSE:To reduce a vibration, by setting up each connecting part of connecting rods to one crankshaft driving two compression pistons symmetrically in front and in the rear, in case of a Stirling engine consisting of one expansion piston and two compression pistons. CONSTITUTION:One expansion piston 20 is erected in the center, and two compression pistons 11a and 11b are symmetrically set up right and left. Each cylinder is connected together by a heat exchanger 21, a heat accumulator 22 and a radiator 26, constituting a Stirling cycle. Each piston is driven by a one crankshaft 14, and at a crankpin 15a, the expansion piston 20 and one compression piston 11b are connected together with connecting rods 18 and 13b. In front and in the rear of this crankpin 15a of the crankshaft 14, there are provided with crankpins 15b and 15c as shifted as far as 180 deg. in phase, two connecting rods 13a and 13c driving one compression piston 11a are connected to these two crankpins. |
