  • Method and apparatus for closed-loop pressure washing using ozonation
    Patent number: 6068003
    Abstract: A portable parts washer flows a washing agent over an object to remove any contaminants. The washing agent and contaminants flow into a basin mounted below the object. The washing agent is drawn from the basin and used to wash the object to provide a closed-loop system. A venturi-type injector mixes ozone from an ozone generator with the washing agent. A pump draws the washing agent from a first inlet to the basin, forces the washing agent through the injector, and returns the washing agent through a first outlet to the basin. Various splash protection mechanisms are used to protect an operator from any substances that may splash off of the object.
