<p>Disclosed is a Stirling engine, comprising a gas distribution cylinder (1), a gas distribution piston (3), a heating device (10), a cooling device (11), a working cylinder (5) and a working piston (7); wherein the working piston (7) is adapted to the working cylinder (5) in a sealing way via the piston ring (8) and capable of sliding reciprocatingly; the gas distribution cylinder (1) is connected to the working cylinder (5) via a gas flow channel (9) and the gas distribution piston (3) reciprocatingly moves synchronous to the working piston (7); the gas flow channel (9) has two branches, and the two gas flow channel branches (9) respectively lead to the left and right inner cavities of the working cylinder (5); and the right inner cavity is connected with the gas flow channel (9) via an exhaust valve (14), an actuating portion opposite to the exhaust valve (14) being provided on the right side of the working piston (7). This Stirling engine has a good sealing effect, and reduces the leakage of the working gas so as to make contributions to the improvement of efficiency.</p> |
