  • Pressure Washer Device Employing a Cool Bypass
    Publication number: 20130291973
    Abstract: A pressure washer device is provided that employs an unloader bypass valve that directs a selective amount of fluid via a small diameter bypass line back to a water storage tank. The small amount of fluid allows for the pump to remain working and introduces cooler water into a bypass circuit, thereby allowing the thermal relief valve to be omitted. The diameter of the bypass line is of such a diameter to prevent siphonage of the detergent associated with the pressure washer system into the water storage tank as well.
