Abstract: An item is cleaned in a portable lavage device comprising a moveable tank for holding a cleansing liquid, a pump and flow restricting mechanism coupled to the tank for circulating the cleansing liquid under a pressure which gradually and cyclically varies from a maximum to a minimum pressure greater than zero to reduce noise during operation of the device, and spaced nozzles coupled to the circulating pump and flow restricting mechanism and arranged to spray the cleansing liquid under varying pressure against an item to be cleaned.This is a division of application Ser. No. 248,510, filed Mar. 27, 1981, now U.S. Pat. No. 4,402,331.
