Patent number: 9399230Abstract: A nozzle for use in a high pressure water jetting system is provided including a stationary housing, a rotating shaft, and a central passage within the shaft for communicating high pressure fluid to the nozzle. The shaft may include communication passages to provide fluid from the central passage to a forward fluid pressure chamber defined between an outer peripheral surface of the shaft and the housing. A rear fluid pressure chamber may be defined between the shaft and the housing and a restriction may be defined between the housing and the inlet end of the shaft, the restriction configured to receive fluid from the rear fluid pressure chamber and transport it to a chamber communicating with the atmosphere. The restriction may be formed as an annular gap between the housing and the inlet end of the shaft and configured to decrease in volume when the shaft moves axially forward.Type: GrantFiled: January 16, 2014Date of Patent: July 26, 2016Assignee: NLB CORP.Inventors: Donald Anthony Wojciechowski, III, Matthew O. Herhold

Patent number: 8298349Abstract: A fluid nozzle for use in a high pressure water jetting system includes a housing to be fixed to a source of high pressure water. The housing receives a rotating member and an inner peripheral bore. The rotating member includes a shaft received within the housing, and a nozzle extending outwardly of the housing, the nozzle having openings extending along a direction having a component both forwardly along an axis of rotation of the shaft and the nozzle, and radially outwardly relative to the central axis. A central passage within the shaft communicates high pressure fluid to the nozzle. The shaft includes leakage paths to provide leakage fluid from the central passage to an interface between an outer peripheral wall of the shaft and an inner peripheral wall of the bore in the housing. The leakage paths communicate fluid to a forward fluid pressure chamber, and to a rearward fluid pressure chamber.Type: GrantFiled: August 13, 2009Date of Patent: October 30, 2012Assignee: NLB Corp.Inventors: Donald Anthony Wojciechowski, III, Matthew O.
