PURPOSE:To enable a free-piston type Stirling engine to be easily started by means of a simple starting equipment by causing a pressure fluctuation to take place at the time of starting in a gas spring chamber in the engine. CONSTITUTION:In a free-piston type Stirling engine which is operated by the free vibration of a displacer 11 performing a reciprocating motion in the piston, a gas spring chamber 10, which is compressed and expanded in response to the vertical motion of the displacer 11, is connected to the chamber of a small piston 9, which is driven by a motor, consisting of a stator winding 5 and a rotor 6, provided on the outside of the engine. When the engine is started, only by driving the motor to cause the vertical motion of the small piston 9 to take place, the pressure in the gas spring chamber 10 is fluctuated, and the displacer 11 piston is caused to perform a reciprocating motion, and then, the working gas is caused to reciprocate between the high temperature space 15, a heater 12, a regenerator 13, a cooler 14, and the low temperature space 16 so that the engine is started. |
