Abstract
The folded channel radial pump assembly (10) comprises a housing (12) having therein a stepped diameter bore (14) receiving a rotor (30). The rotor (30) is attached by way of a flexible coupling (50) with the output shaft (61) of an electric motor (60) attached to the housing (12). The rotor (30) includes one or more intake (26, 36) and exhaust (28, 38) ports, the ports (26, 28, 36, 38) being radially aligned and communicating with the stepped bore (14). The rotor (30) includes one or more pairs of radial openings (70, 72; 170, 172) disposed substantially parallel to one another and each pair connected by way of an axial passageway (74; 174), one radial opening (70, 170) of the pair being aligned axially with the respective set of intake (26, 36) and exhaust (28, 38) ports and the other radial opening (72, 172) having therein a resilient mechanism (77, 177) biasing a piston ( 76, 176) and follower mechanism (75, 175) outwardly into engagement with an eccentric diameter section (24, 124) of the stepped bore (14). Rotation of the rotor (30) by the motor (60) causes the follower mechanism (75, 175) and piston (76, 176) to reciprocate within the other radial opening (72, 172) and effec…
