That is, the body 50 is divided into a ring-shaped part 52 joined to the heat transfer head 40 and a cap-shaped part 53 joined to the ring-shaped part 52. Both the ring-shaped part 52 and the cap-shaped part 53 are made of stainless steel.

- the cavity 80 communicates with the compression space 45 via a check valve 90 arranged on the end face of the piston 12.
- a plurality of concave portions 81 forming a gas bearing are arranged at a predetermined angular interval on the same circumference.
- a metal tube 82 is driven into the bottom of the piston 81 so as to penetrate the piston 12, and working gas is supplied from the cavity 80 to the recess 81 through the metal tube 82.
- Two or more annular rows of the concave portions 81 are formed at intervals in the axial direction of the piston 12. That is, gas bearings are formed in two or more places.

- Working gas is supplied from the cavity 85 to the concave portion 86 through the metal thin tube 87 driven into the bottom of the concave portion 86.
- the Stirling engine 1 operates as follows. When an alternating current is supplied to the coil 21 of the linear motor 20, a magnetic field penetrating the magnet 24 is generated between the outer yoke 22 and the inner yoke 23, and the magnet 24 reciprocates in the axial direction. By supplying power at a frequency that matches the resonance frequency determined by the total mass of the piston system (piston 12, magnet holder 14, magnet 24, and spring 30) and the panel constant of spring 30, the piston system becomes smooth. Start a sinusoidal reciprocating motion.
- the resonance frequency determined by the total mass and the panel constant of the spring 31 is set so as to resonate with the drive frequency of the piston 12.
- the displacer 13 Due to the reciprocating motion of the piston 12, compression and expansion are repeated in the compression space 45. With this change in pressure, the displacer 13 also reciprocates. At this time, a phase difference occurs between the displacer 13 and the piston 12 due to a flow resistance or the like between the compression space 45 and the expansion space 46. Thus, the displacer 13 having the free piston structure oscillates synchronously with the piston 12 with a predetermined phase difference.
- the working gas that reciprocates between the compression space 45 and the expansion space 46 is subjected to internal heat exchange.
- the heat of the heat is transmitted to the heat transfer heads 40, 41 through the internal heat exchangers 42, 43. Since the working gas flowing into the regenerator 47 from the compression space 45 has a high temperature, the heat transfer head 40 is heated, and the heat transfer head 40 becomes a warm head. Since the working gas flowing into the regenerator 47 from the expansion space 46 has a low temperature, the heat transfer head 41 is cooled, and the heat transfer head 41 becomes a cold head.
- the Stirling engine 1 functions as a refrigeration engine by dissipating heat to the atmosphere from the heat transfer head 40 and lowering the temperature in a specific space with the heat transfer head 41.
- the regenerator 47 does not transmit the heat of the compression space 45 and the expansion space 46 to the space on the other side, but functions to pass only the working gas.
- the high-temperature working gas entering the regenerator 47 from the compression space 45 via the internal heat exchanger 42 gives the heat to the regenerator 47 when passing through the regenerator 47, and in a state where the temperature is lowered, the expansion space 46 Flows into.
- the low-temperature working gas that has entered the regenerator 47 from the expansion space 46 via the internal heat exchanger 43 recovers heat from the regenerator 47 when passing through the regenerator 47. Flows into. That is, the regenerator 47 serves as a heat storage.
- a part of the high-pressure working gas in the compression space 45 enters the cavity 80 of the piston 12 and the cavity 85 of the displacer 13 through the check valve 90. And it gushes from the concave parts 81 and 86. Due to the ejected working gas, a gas film is formed between the outer peripheral surface of the piston 12 and the inner peripheral surface of the cylinder 10 and between the outer peripheral surface of the displacer 13 and the inner peripheral surface of the cylinder 11. Contact between the cylinder 10 and the displacer 13 and the cylinder 11 is prevented. Therefore, there is no problem of energy loss due to friction of the contact portion or wear of the contact portion.
- the piston 12 and the cylinder 10 are formed of a metal such as aluminum or stainless steel.
- the other part of the displacer 13 and the cylinder 11 is made of a metal, and the rest is made of a low thermal conductive material such as a synthetic resin.
- FIGS. 2 is a cross-sectional view of the displacer and the cylinder
- FIGS. 3 and 4 are enlarged cross-sectional views of a portion surrounded by a circle A in FIG.
- the displacer 13 and the cylinder 11 that receives the displacer 13 are both formed of metal on the side facing the compression space 45 and made of a low heat conductive material on the side facing the expansion space 46.
- the metal part 13a and the low thermal conductive material part 13b of the displacer 13 and the metal part 1 la and the low thermal conductive material part 1 lb of the cylinder 11 are fitted together in such a manner that the latter covers the former with V, even if the gap is shifted. In other words, the fitting is performed.
- the fitting portion is joined by an adhesive, but in the displacer 13 which reciprocates at a high speed by itself, the fitting portion is joined by a combination of the screwing and the adhesive to increase the joining strength.
- Figures 3 and 4 show examples of the screwing structure of the fitting part.
- a screw portion 13c is formed by a male screw portion formed on the outer peripheral surface of the metal portion 13a and a female screw portion formed on the inner peripheral surface of the low heat conductive material portion 13b. Is configured.
- the screw portion 13c is provided near the center of the overlap at the place where the metal portion 13a and the low thermal conductive material 13b overlap, and the screw groove is not exposed to the outside.
- the thread groove serves as a passage for the working gas, and it is possible to prevent an unexpected flow (leakage) of the working gas from occurring inside and outside the displacer 13.
- the metal portion 11a and the low thermal conductive material portion l ib of the cylinder 11 do not necessarily move because the cylinder itself does not move, so that the bonding strength does not become insufficient even with the adhesive alone.
- a threaded portion is provided between the metal part 11a and the low thermal conductive material part l ib to increase the joining strength. You may try.
- the adhesive may be applied to an appropriate portion of the contact surface between the metal portion 13a and the low thermal conductive material portion 13b.
- the adhesive may be applied to the entire periphery of the contact surface, the leakage of the working gas can be prevented. Applying it to the entire contact surface can further strengthen the bonding. The same is true for cylinder 11.
- the metal portion 13a has a larger outer diameter than the low thermal conductive material portion 13b.
- the inner diameter of the metal portion 11a is smaller than that of the low thermal conductive material portion 1 lb.
- the dimensional accuracy of the low thermal conductive material is lower, but by designing in this way, the space between the low thermal conductive material portions 13b and lib is sufficiently ensured and accidental contact can be prevented.
- Low thermal conductive material part The expansion (13b, 13b) of the coefficient of expansion is large, so even if the dimensions change significantly due to temperature changes, this can confirm safety (prevention of contact). This interval can be set to a value such as 120 m.
- the metal parts 13a and 11a can have high dimensional accuracy, the fitting accuracy is established between them. Then, a gap in which the gas bearing functions is obtained. This gap can be set, for example, to a value of 20 / zm.
- the boundary between the metal portion 13a and the low thermal conductive material portion 13b in the displacer 13 and the boundary between the metal portion 1 la and the low thermal conductive material portion 1 lb in the cylinder 11 are mutually moved by the displacement of the displacer 13.
- the distance D fluctuates.
- the positional relationship (distance) between the boundary of the displacer 13 and the boundary of the cylinder 11 is set so that the boundaries do not overlap, that is, the distance D does not become zero. Therefore, even if a reverse step is generated between the metal part and the low thermal conductive material part at the boundary between the metal part and the low thermal conductive part, the movement of the displacer 13 is hindered by the attractive force of the reverse steps. There is nothing.
- the low thermal conductive material portions 13b and lib are formed by injection molding of a synthetic resin. This makes it possible to mass-produce the low heat conductive material portions 13b and lib at low cost.
- the synthetic resin for example, polycarbonate can be used.
- the metal portion 11a of the cylinder 11 is integrated with the cylinder 10.
- 10a shown in FIG. 2 is a bridge portion extending from the cylinder 10.
- the present invention can be used for all Stirling engines.
