<p><P>PROBLEM TO BE SOLVED: To provide a current control reciprocating fluid pressure feeding unit capable of press-feeding fluid by a single magnet. <P>SOLUTION: A current control reciprocating fluid pressure feeding unit is equipped with a chamber, with a magnet, with a coil, with a first inlet and first outlet provided to one end of the chamber, with a second inlet and second outlet provided to the other end of the chamber, with a first valve membrane which is provided among the first inlet, first outlet and chamber and which is moved between a first position in which the first inlet is closed and the first outlet is not closed and a second position in which the first outlet is closed and the first inlet is not closed, and with a second valve membrane which is provided among the second inlet, second outlet and chamber and which is moved between a third position in which the second inlet is closed and the second outlet is not closed and a fourth position in which the second outlet is closed and the second inlet is not closed. When the magnet comes close to the first valve membrane, the first valve membrane and the second valve membrane are placed in the first position and the fourth position, respectively. When the magnet comes close to the second valve membrane, the first valve membrane and the second valve membrane are placed in the second position and the third position, respectively. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
