Abstract
A scroll assembly for use with a fluid machine, such as a wet/dry vacuum appliance, is described. Such scroll assembly may include a base portion, a cover portion configured to couple to the base portion, and a cavity between the base portion and the cover portion, wherein the cover portion and the base portion collectively form a labyrinth seal when coupled together, and wherein the labyrinth seal at least partially circumscribes the cavity. A vacuum appliance may include a scroll assembly coupled at least partially therein. A method of exhausting air from a vacuum appliance may include energizing a vacuum motor, thereby drawing air into the scroll assembly, allowing the air to contact a flow splitter, and allowing the air to exit the vacuum appliance.
