  • Patent number: 6206043
    Abstract: A diverter valve comprises a body defining a first, a second, and a third orifice, a flipper operably positioned to substantially prohibit flow through one of the first, the second, and the third orifices, and a flipper drive mechanism drivably coupled to the flipper. The flipper drive mechanism comprises a motor, a cam drivably coupled to the motor and including a cam position indicator, a follower drivably coupled to the cam translating rotational motion of the cam into reciprocal motion to drive the flipper, and a motor control circuit in sensory communication with the cam position indicator. The motor control circuit couples an external source of electrical power to the motor to energize the motor to drive the cam to a first and a second predetermined position. The motor control circuit includes a first controllable switch in series with a first position switch. This first position switch opens in response to the cam position indicator indicating that the cam is at the first predetermined position.
