ABSTRACT:
A motor driven diverter valve is provided which diverts fluid flow from a single inlet port to either one of two outlet ports, or vice versa. The valve finds general, although not exclusive, utility in solar heating systems for swimming pools, in which the valve is used selectively to divert water flow from the normal pump-filter loop of the pool installation through the solar collectors. In such an application, the diverter valve of the invention may be operated automatically in response to an electrical switching signal derived, for example, from a temperature controller in the solar heating control system, to direct the water through the solar collectors for one operating position of the valve, and to by-pass the solar collectors for a second operating position. The valve of the invention uses two synchronous permanent magnet drive motors which together consume less power than the conventional single shaded pole motor/gear box arrangement of the prior art.
