1. A dishwasher for treating utensils according to an automatic cycle of operation, comprising:

  • a tub at least partially defining a treating chamber for receiving utensils for treatment according to the automatic cycle of operation;

    a sprayer for spraying liquid into the treating chamber and having a body, the body having an exterior and an inner surface defining an interior, wherein the interior forms at least a portion of a liquid passage and at least one outlet including an aperture extends from the interior to the exterior, wherein the inner surface includes a rib defining a periphery surrounding the at least one outlet; and

    a slidable valve body located within the interior including a membrane having at least one opening;

    wherein the membrane sealingly abuts the rib to form a liquid seal between the rib and the membrane and where the membrane and the sprayer are operably coupled wherein, during use, rotation of the sprayer causes reciprocating movement of the membrane relative to the sprayer such that at least a portion of the at least one opening passes within the periphery to fluidly couple the interior to the at least one outlet and provide for a fluid path from the interior, through the at least one opening, and through the at least one outlet to emit a spray of liquid from the sprayer into the treating chamber.
