<p>PURPOSE:To transfer a fluid efficiently by providing a piston in a pressure-tight cylinder, and reciprocating the piston by a magnetic force so as to lead in and lead out the fluid in the cylinder. CONSTITUTION:A piston 2 is provided in a pressure-tight cylinder 1, and the piston 2 is reciprocated by a magnetic force. In the right side chamber 1R of the pressure-tight cylinder 1, a check valve type right side discharge valve 3 and a right side suction valve 4 are communicated and connected. On the other hand, also in the left side chamber 1L of the cylinder 1, a check valve type left side discharge valve 7 and a left side suction valve 8 are communicated and connected. The left side discharge valve 7 and a fluid leading-out port 5, and the left side suction valve 8 and a fluid leading-in port 6 are communicated and connected respectively. As a result, a sealed container can be applied as the cylinder 1, and no leakage is generated even though no sealing member or the like is used. The suction and the discharge can be carried out continuously following the constant reciprocation of the piston 2.</p> |
