    • PROBLEM TO BE SOLVED: To heighten the efficiency of a rotary hydraulic machine by minimizing leak of heat and pressure of a working fluid in the rotary hydraulic machine having at least a first energy converting means and a second energy converting means disposed inside and outside in the radial direction. SOLUTION: The first energy converting means formed by a cylinder member 30 and a piston 41 is disposed in the center of a rotary chamber 14, and a second energy converting means formed by a vane 42 is disposed on the outer peripheral side of the rotor chamber 14. A high pressure and high temperature working fluid leaking from the center side is recovered by the low pressure and low temperature working fluid on the outer peripheral side of the rotor chamber 14, and the leaked high pressure and high temperature working fluid is used without loss to height the efficiency of the whole rotary hydraulic machine. As the low pressure and low temperature working fluid is disposed on the outer peripheral side of the rotor chamber 14, sealing for preventing the working fluid from leaking from the rotor chamber 14 to the outside can be facilitated, and also heat insulation for preventing heat from leaking from the rotor chamber 14 to the outside can be facilitated.

    • PROBLEM TO BE SOLVED: To ensure sufficiently the cross-sectional area of a flow passage at the entrance and exit of a fluid passage and thereby to minimize a pressure loss by forming the entrance of a high-temperature fluid passage and the exit of a low- temperature fluid passage in one end part in the direction of the flow passage of a heat exchanger and by forming the exit of the high-temperature fluid passage and the entrance of the low-temperature fluid passage in the other end part in the direction of the flow passage thereof. SOLUTION: A large number of heat transfer plates S1 bent zigzag are joined to the inner periphery of an outer casing 6 and the outer periphery of an inner casing 1 and thereby high-temperature combustion gas passages 4 and low-temperature air passages 5 are formed alternately. The high-temperature combustion gas passage 4 and the low-temperature air passage 5 are cut in an angled shape at one end part thereof and the entrance 11 of the combustion gas passage and the exit 16 of the air passage are formed by closing up one and the other sides of this part. The exit 12 of the combustion gas passage and the entrance 15 of the air passage are formed likewise in the other end parts of the high-temperature combustion gas passage 4 and the low-temperature air passage 5. Accordingly, it is possible to ensure sufficiently the cross-sectional area of a flow passage at the entrance and exit of the fluid passage and thereby to minimize a pressure loss.
