PUMPING DEVICE WITH DIRECT DRIVE

摘要

A pumping device configured to directly drive a reciprocating member to pump a fluid. In one embodiment, the pumping device comprises a body forming an internal chamber. The reciprocating member may be disposed in the body, the reciprocating member having a first end, a second end, and an axis. The embodiment may further include a drive system magnetically coupled with the reciprocating member, the drive system comprising a first conductive body affixed relative to the reciprocating member. The drive system may be configured to induce a first magnetic field by energizing the first conductive body. The reciprocating member may be configured to induce a second magnetic field in a manner that causes the reciprocating member to move between a first position and a second position to fill and evacuate the internal chamber with a fluid.
