  • Patent number: 10670086
    Abstract: A washing machine transmission actuator employs a rotating cam for separating a clutch. The cam is rotated by a ring gear communicating with a pinion gear on a motor providing improved minimum torque for a given motor power and thus improved energy efficiency.
    Type: Grant

  • Patent number: 7329338
    Abstract: A water treatment system includes a tank that contains a particle bed for removing minerals from water flowing through the tank. The regeneration of the particle bed is conducted in response to measuring its conductivity. A probe is provided for that measuring. That probe has a sleeve with a tubular portion for extending through and engaging a wall of the tank. A probe body is removably received within an aperture of the sleeve and includes a pair of electrodes that project inside the tank. A retainer that secures the probe body within the sleeve. Different mechanisms are provided for securing the sleeve to the tank depending upon the particular materials used to fabricate the tank.

  • Patent number: 7004200
    Abstract: A flow control valve controls a flow of water through a passage to a brine tank of a water treatment apparatus. A valve seat is between first and second sections of the passage. The valve seat has a first end with a concave surface facing the first section and an aperture extending from the concave surface to a second end that faces the second section. A groove in the concave surface extends from the first end to the aperture. A valve element moves within the first section in response to pressure of the water in the first section thereby varying the size of a path through the passage by an amount that varies as a function of the water pressure. The action of the valve element maintains a substantially constant flow rate through the flow control valve regardless of water pressure variation.
