Abstract
A rotary pump having an eccentric rotor (14) adapted to
effect eccentric motion relative to the axis of the pump shaft
(7) within a pump casing (1) to cause pumping action in a
pump chamber. The pump comprises a pump casing (1), a
pump shaft (7) mounted on the pump casing, a pair of
eccentric rotors (14) mounted on the pump shaft (7) with
angular spacing apart of 180°, a pair of diaphragms (24) on
the eccentric rotors (14) to define a pair of pump chambers P,
a partition member (36) adapted to divide the pump chamber
into a suction chamber (Pi) and an exhaust chamber (Pe), and
an intake port (42) and an exhaust port (43) in communica
tion with the suction and exhaust chambers, respectively, the
intake port being cut off from its communication with the
exhaust port by the partition member during rotation of the
pump shaft.
