摘要： A diverter valve for diverting fluid flow between an inlet and an outlet selected from among several outlets is disclosed. The diverter valve disclosed is useful for distributing fluids in laundry applications, especially automatic clothes washers and the like. It includes a body, a valve member, a motor to operate the valve, an actuable switch, a cam mechanism to de-energize the motor upon movement to a position, and a housing for the device.

摘要： A programmer for an appliance having a single timing motor drive for a rotating cam drum which actuates plural appliance program function switches. An advance pawl drives the cam drum in one direction when selectively engaged with a toothed wheel on the drum and drives through a first rotary frictional coupling. A gear train drives continuously through a second rotary frictional coupling and drives the cam drum in a reverse direction when the advance pawl is disengaged. When the pawl is engaged, the second rotary frictional coupling slips and is overdriven in a direction opposite its driving direction by said first frictional coupling.

摘要： 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. The motor control circuit further includes a second controllable switch in series with a second position switch and in parallel to the first controllable switch and the first position switch. This the second position switch opens in response to the cam position indicator indicating that the cam is at the second predetermined position.
摘要翻译：分流阀包括限定第一孔，第二孔和第三孔的主体，操作地定位成可以基本上禁止流过第一孔，第二孔和第三孔中的一个的挡板，以及可驱动地联接到挡板的挡板驱动机构。引导器驱动机构包括马达，可驱动地联接到马达的凸轮并且包括凸轮位置指示器，可驱动地联接到凸轮的跟随器，该凸轮将凸轮的旋转运动平移成往复运动以驱动推杆，以及感应器中的马达控制电路与凸轮位置指示器通讯。电动机控制电路将外部电源耦合到电动机以对电动机通电以将凸轮驱动到第一和第二预定位置。马达控制电路包括与第一位置开关串联的第一可控开关。响应于凸轮位置指示器指示凸轮处于第一预定位置，该第一位置开关打开。马达控制电路还包括与第二位置开关串联并与第一可控开关和第一位置开关并联的第二可控开关。这个第二位置开关响应于凸轮位置指示器而指示凸轮处于第二预定位置而打开。
