Abstract (en)
[origin: EP0211314A1] 1. An electromagnetic reciprocating piston pump, in which a reciprocating piston is moved to and from in a cylindrical tube made of non-magnetic material by means of at least one coil arranged on the outside of the cylindrical tube, and in which electromagnetically actuated valves periodically close the inlets and outlets, characterized in that three straight cylindrical tubes (1, 2, 3) are arranged parallel to one another between two collectors (4, 5), each tube containing a reciprocating piston (6, 7, 8) which is at least partially made of soft iron, and carrying outer coils (12 to 17) for moving the piston, and in that two of these cylindrical tubes (2, 3) are each provided, in the central zone between the collectors, with a connection piece (18, 19) which acts as an inlet or outlet respectively, wherein the pistons in these cylindrical tubes, the so-called valve pistons, depending on their position, either close the connection piece or put it in communication with one collector or the other.
