<p><P>PROBLEM TO BE SOLVED: To provide a liquid pump with a very simple mechanism, which is capable of enhancing cost performance by reducing the number of parts required for manufacturing, making smaller in size, and controlling a pump flow easily without generating noises during operation. <P>SOLUTION: An inlet/outlet 3 is provided in the tip of a thin tubular inflow/outflow passage 1a, and liquid is kept in a pressurized container 1 in which a volumetric capacity is varied at least partially by an external force. The capacity is varied by an operation body 4 formed of a shape memory alloy with reversible shape memory effect that is repeatedly expanded/contracted by being heated/cooled. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
