Abstract

PURPOSE:To improve the reliability of engine by employing shape-memory alloy to vary the control piston thus to vary the volume of an enclosed container of stirling engine thereby controlling the pressure of working fluid. CONSTITUTION:A displacer 18 is arranged in an enclosed container 14 encapsulated with working fluid while a cylinder 24 containing a control piston 25 is fixed. The amplitude of up/down motion of displacer is maintained at proper level by means of a displacer rod 22 and a gas spring 21 surrounded by a bearing 23. When reducing the volume in said container 14 to increase the angular speed of up/down motion of the piston and the displacer 18, a command is provided to a temperature regulator 30 to rise the temperature of fluid flowing through a heatexchanger 28 thus to rise the temperature of shape-memory alloy coil spring 26 and to move the control piston 25 to the right. While when lowering the angular speed, the temperature of fluid flowing through the heatexchanger 28 is lowered.

幅で運動σせる役目をしている。It is a piston that does work for a load 10 such as a pump. Reference numeral 11 denotes a gas spring surrounded by a displacer rod 12 and a bearing 13, whose volume changes as the displacer 5 moves downward.As the pressure changes with the change in volume, it acts as a spring and moves the displacer 5 with an appropriate amplitude. It has the role of causing motion σ.

る。The displacer 5 and the piston 9 are moving up and down within the closed container 1. At this time, the phase angle of the position of the displacer 5 is slightly ahead of the phase angle of the position of the piston 9. Along with the movement of the displacer 5 and the piston 9, heat is applied to the working fluid through the heating device 2,
Conversely, heat is removed from the working fluid through the cooler 3, and a portion of the heat given to the working fluid through the knife heater 2 is used for the work that the piston 9 does to the load 10.

キはバルブ装置を切換えて、密閉容器１内の作動流体を
容器内に送り込むのである。More specifically, a working fluid container and a compressor for compressing the working fluid are separately provided, and when the pressure inside the sealed container 1 is decreased by -L, the working fluid in the working fluid container is compressed into the sealed container by the compressor. When the pressure inside the closed container 1 is lowered, the valve device is switched and the working fluid inside the closed container 1 is sent into the container.

ーサ５の運動する角速度を下げるのである。In this way, the pressure of the working fluid in the closed container 1 is reduced to -L
By increasing the angular velocity of the piston 9 and the displacer 5, the angular velocity of the piston 9 and the displacer 5 is decreased, and by lowering the pressure of the working fluid in the closed container 1, the angular velocity of the piston 9 and the displacer 5 is decreased.

。It is necessary to prevent lubricating oil from entering the high-temperature parts of the compressor-regenerator matrix and clogging the matrix, so the structure must be such that lubricating oil does not mix with the working fluid. As a result, it is difficult to lubricate the discharge valve and suction valve, resulting in low reliability.As a result, the reliability of the entire Stirling engine system is low.
