Patent number: 8888016Abstract: 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.Type: GrantFiled: March 14, 2013Date of Patent: November 18, 2014Assignee: Karcher North America, Inc.Inventors: Paul W. Linton, Derek Knight

Patent number: 8876577Abstract: A floor care apparatus is provided that utilizes at least one cylindrical pad to remove a floor finish. More specifically, a cylindrical pad having an abrasive surface is integrated onto a cylindrical scrubber brush or associated core or roller commonly used in the art. The main outwardly-facing surface of the pad contacts the floor to remove a predetermined amount of floor finish wherein generated debris is expelled away from the pad. After finish removal, a new layer of finish is applied to the floor. Thus, the need to remove all finish layers from a flooring surface is alleviated, which saves time and money.Type: GrantFiled: October 13, 2011Date of Patent: November 4, 2014Assignee: Karcher North America, Inc.Inventors: James D. Lombard, James L. Young
