Abstract: A reservoir for retention and delivery of a liquid detergent and water mixture includes an upright standing, multiwalled main body portion, a vertical duct having a passageway therethrough and a hollow outlet tube. The reservoir is constructed of a single molded piece of plastic and the main body portion includes a bottom wall and four side walls which adjoin one another to define an open cavity. The outlet tube which extends through one side wall connects to the vertical duct and opens into the passageway. The free end of the outlet tube is of a design which allows sealing engagement of the outlet tube with a suction conduit. There is a small aperture through the wall of the vertical duct, adjacent to the bottom wall of the main body portion. This aperture provides a path for a liquid detergent and water mixture to flow from within the open cavity into the passageway of the vertical duct.

Abstract: A fluid control valve includes a valve body having a passageway, a valve stem, a valve seat, a floating stem end member and a captive internally threaded insert. The valve stem has a molded-on, color-coded external thread mating with the internal thread of the color-coded insert so as to advance or retract the stem through the valve body as the stem is turned by an operating knob. The stem end member includes a pair of retaining arms which snap over a shoulder on the stem and these arms are confined within the valve body. These arms retain the stem end member on the stem while still permitting free rotation of the stem within the stem end member. As the stem advances into the valve body, the stem end member is moved into sealing contact with the valve seat, thereby blocking the continued passage of water from an inlet port to an outlet port. The valve seat also serves as a union nut mount, and is slotted for easy removal from the rear by use of a screwdriver for servicing.
