Patent number: 11958065Abstract: A water delivery device includes an inlet connector, a sprayface assembly, and a selection engine. The inlet connector is configured to couple the water delivery device to a water supply. The sprayface assembly includes a plurality of nozzles that are configured to produce a plurality of spray patterns. The selection engine fluidly couples the inlet connector to the sprayface assembly and controls flow to each one of the plurality of nozzles to determine the spray pattern produced at the sprayface assembly. The selection engine is configured to switch directly from any one of the plurality of spray patterns to any other one of the plurality of spray patterns in response to a single actuation of the selection engine.Type: GrantFiled: September 4, 2020Date of Patent: April 16, 2024Assignee: KOHLER CO.Inventors: Evan Yee, Brian S.

Publication number: 20230087500Abstract: A cartridge valve includes a housing, a stem adapter, and a stem assembly. The stem adapter includes a body defining a first hole, which extends in a longitudinal direction. The stem assembly includes a first stem component and a second stem component. The first stem component includes an arm and a spherical portion that is configured to be at least partially positioned within the first hole and defines an opening. The second stem component has a body that is configured to be at least partially received within the opening of the first stem component. The spherical portion is configured to expand in size in response to the first end inserting a portion of the body of the second stem component into the opening in the first stem component, which increases a frictional resistance induced by relative rotation between the stem assembly and the stem adapter.Type: ApplicationFiled: November 30, 2022Publication date: March 23, 2023Applicant: Kohler Co.Inventors: David H.
