Zusammenfassung:	Multi-port valve assemblies (10) with, typically, two-piece housings (14,18) are disclosed. Particularly useful in connection with swimming pools and associated water pumps, the assemblies avoid reliance on an elongated handle to effect rotation of the internal structure of the valve. Instead, the assemblies utilize a knob (98)--which users need not lift--coupled to a post (50) in which an elongated slot is formed. Doing so avoids breakage problems associated with use of elongated handles while reducing wear of internal seals. Each valve assembly additionally may include a cam (154) having non-semicircular, asymmetrically-shaped recesses (158) into which followers (170A-B) attached to a shaft (142) passing through the elongated slot are received.
