2. Description of the Related Art Conventionally, the structure and operation of a free piston type VM engine of this type will be described with reference to FIG. The high temperature displacer 1 has a stepped rod in which a displacer piston rod 2 having a diameter a and a displacer piston rod 3 having a diameter b are connected in series, and the end of the displacer piston rod 3 is forcibly forced by a linear actuator 4 in the drawing. Driven up and down. On the other hand, on the outside of the cylindrical sleeves 5a and 5b,
From the top in the figure, the high temperature side high temperature part heat exchanger 6a, the high temperature side regenerator 7, the high temperature side middle temperature part heat exchanger 8, the low temperature side middle temperature part heat exchanger 9, the low temperature side regenerator 10 and the low temperature side low temperature part heat exchange. A heat exchanger 11 is provided, and the high temperature side middle temperature section heat exchanger 8 and the low temperature side middle temperature section heat exchanger 9 are integrated via a ring-shaped portion 12.
Further, a high temperature side cylindrical shell 13 and medium temperature side cylindrical shells 14a, 14b are arranged outside the high temperature side regenerator 7, the high temperature side intermediate temperature part heat exchanger 8, and the low temperature side intermediate temperature part heat exchanger 9, respectively. Further, the low temperature side regenerator 10 and the low temperature side low temperature part heat exchanger 11
A low temperature side cylindrical shell 15 is disposed on the outer side of and is isolated from the outside. An electric heater 6 is provided at the head of the high temperature side cylindrical shell 13 to take out heat from the high temperature side middle temperature section heat exchanger 8 and the low temperature side middle temperature section heat exchanger 9 for heating, and to cool the low temperature side low temperature side heat exchanger 9. Cold heat is applied from the partial heat exchanger 11. Water is arranged as a carrier medium outside each heat exchanger. Here, the working gas such as helium in the high temperature working space 16 and the middle temperature working space 17 heated by the electric heater 6 heats the outer water via the high temperature side middle temperature section heat exchanger 8, while the low temperature working space is heated. The working gas in 18 and the medium temperature working space 17 heats the outer water via the low temperature side medium temperature heat exchanger 9 and removes heat from the outer water via the low temperature side low temperature heat exchanger 11. At this time, the vertical movement of the high-temperature displacer 1 moves the working gas between the high-temperature operating space 16 and the intermediate-temperature operating space 17 to the high-temperature high-temperature heat exchanger 6a, the high-temperature regenerator 7, and the high-temperature intermediate-temperature heat exchanger. 8
Alternate through. Further, the vertical movement of the low temperature displacer 19 causes the working gas to pass between the low temperature operating space 18 and the intermediate temperature operating space 17 through the low temperature side low temperature part heat exchanger 11, the low temperature side regenerator 10 and the low temperature side intermediate temperature part heat exchanger 9. And let them alternate.
At that time, pressure change occurs due to a change in the ratio of the high temperature working gas and the low temperature working gas, but the low temperature displacer 19 is vibrated by the volume change caused by the difference in the diameters a and b of the displacer piston rods 2, 3. The cold displacer 19 operates so as to generate a force and maintain a certain phase difference from the hot displacer 1. At this time, the temperature of each operating space is kept constant by the heat storage action of each regenerator 7, 10. The output of the engine is each heat exchanger 6
The heat release and absorption of a, 8, 9 and 11 are used for heating and cooling. Further, 20 is an auxiliary mechanical spring for the low temperature displacer, 21 is a rod seal for the working space 18, 22 is a mechanical spring for the high temperature displacer, 23 is a buffer chamber for maintaining an appropriate pressure value, and 24 is a rod seal for the buffer chamber. , 25 are gas spring chambers in the low temperature displacer.

By the way, the conventional free piston type VM engine has the following problems because it is configured as described above. Since the high temperature displacer mechanical spring 22 is provided in the buffer chamber outside the engine, the entire VM engine becomes large. Further, in the conventional case, since the displacer rod penetrates the low temperature chamber, it is necessary to dispose a seal portion, and there is a possibility that gas leakage or friction loss may occur in this seal portion. It is an object of the present invention to provide a free piston type VM engine that solves the above problems (problems) of the related art.
