Abstract (en)
[origin: US2006127252A1] A reciprocating pump assembly includes a linear electric motor having a cylinder, a rotor, and a stator. A multiple of check valves are located near each end of the cylinder. Pairs of check valves are mounted within a T-shaped fitting which permit each fitting to operate alternatively as an inlet and a discharge depending on the direction of the rotor stroke. Another pump assembly utilizes the rotor to separately drive pistons through pushrods.
