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 spraying system for supplying liquid to the treating chamber and having a sprayer with at least one liquid passage, a first outlet extending to an exterior of the sprayer and in fluid communication with the liquid passage;
a valve body having a first opening in fluid communication with the liquid passage;
a seal located between the first opening and the first outlet, the seal surrounding the first outlet and fluidly sealing the first outlet relative to the valve body, and wherein the seal creates an effective outlet for the first outlet, wherein the effective outlet is larger than the first outlet, and allows for a longer duration of the fluid communication between the first outlet and the first opening; and
wherein the valve body and the sprayer are coupled for relative movement to each other and the first outlet and the first opening are differently sized, and one of the first outlet or the first opening defines a first size and the other of the first outlet or the first opening defines a second size that is larger than the first size, wherein when the valve body moves relative to the sprayer a duration of the fluid communication between the first opening and the first outlet is increased as compared to had the first outlet and the first opening both been the first size.
