ABSTRACT:
Pump apparatus (10; 110) for the controlled ingress and egress of a fluid comprising, a generally cylindrical housing (11; 111), flexible septum (55; 155) disposed within the housing and attached to the housing substantially axially medially thereof, an electromagnet assembly (65; 165, 165') affixed to the septum, a pair of inlet ports (25, 25; 125, 125) in the housing with one disposed to either side of the septum, valves (35; 135) in the inlet ports permitting only ingress of fluid to said housing, a pair of outlet ports (26, 26; 126, 126) in the housing with one disposed to either side of the septum, valves (35; 135) in the outlet ports permitting only the egress of fluid from the housing, permanent magnets (45, 46; 145, 146) disposed proximate the axial extremities of the housing, and a controller (70; 170) for selectively energizing the electromagnet assembly for the controlled displacement of the septum axially of the housing to alternately effect the ingress and egress of fluid from the inlet and outlet ports to either side of the septum.
