Abstract: A parts washer is provided having a cleaning fluid reservoir and a first mechanism provided with structure for performing a first parts washing function utilizing fluid in the cleaning fluid reservoir with the first parts washing function dissipating the cleaning from the reservoir. A second mechanism is provided for performing a second parts washing function utilizing cleaning fluid that increases the volume of cleaning fluid from a supply. A third mechanism is provided for sensing the volume of cleaning fluid in the reservoir and a) enabling operation of the first mechanism and disabling operation of the second mechanism with the cleaning fluid present in the reservoir in a first predetermined volume and b) disabling operation of the first means and enabling operation of the second means with the cleaning fluid present in the reservoir in a second predetermined volume.

Abstract: A parts washer is provided having a reservoir containing a supply of fluid and a first mechanism for pressurizing fluid from the supply and delivering the pressurized fluid to against a part to be washed with the first mechanism including an inlet for fluid from the reservoir which is at least partially immersed in reservoir fluid so that there is a predetermined fluid pressure at the inlet due to the depth of the fluid. Structure is provided for increasing the pressure of fluid at the inlet without changing fluid depth at the inlet.
