Publication number: 20140150894Abstract: A flow path switching valve is disclosed that can be operated remotely simply by turning flow on and off. A mid portion of the body has at least one passage therein leading from a central axial bore to one or more external ports each having a tractor nozzle. The valve outlet connects the axial bore to a cleaning nozzle. A poppet member is received in the central axial bore. In a first position, the poppet member directs fluid flow through the outlet to the cleaning nozzle connected to the outlet. The poppet member, when in a second position, closes the central axial bore through the outlet end of the valve body and permits fluid flow through the tractor nozzles. Selection of the different flow paths is made by simply reducing flow through the valve below a predetermined fluid flow threshold and then increasing the flow rate above the threshold.Type: ApplicationFiled: February 11, 2014Publication date: June 5, 2014Applicant: STONEAGE, INC.Inventor: Gerald P.

Patent number: 8668155Abstract: A high pressure rotary nozzle having a rotating shaft operating within a fixed housing wherein the of axial force which acts upon the shaft due to the fluid pressure at the shaft inlet is balanced by allowing passage of a small amount of the pressurized fluid to be bled to an area or chamber between the outside of the opposite end of the shaft and the inside of the housing where the fluid pressure can act axially in an opposing direction upon the shaft to balance the axial inlet force. The balance of axial forces is self-regulating by controlling escape of the fluid through a tapered or frusto-conical region between the shaft and housing. This further provides a fluid bearing between the two surfaces and allows use of interchangeable rotating jet heads having jet orifices which can be oriented in virtually any desirable configuration including axially forward of the nozzle.Type: GrantFiled: March 14, 2013Date of Patent: March 11, 2014Assignee: Stoneage, Inc.Inventor: Douglas E.

Publication number: 20140008459Abstract: A fluid bearing nozzle assembly is disclosed that has a hollow cylindrical body, an inlet nut fastened to the cylindrical body, and a hollow tubular shaft member coaxially carried within the housing body and captured between the inlet nut and the body. The inlet nut has a stem portion extending into a central bore through the shaft member forming an inlet bearing area rotatably carrying the shaft member thereon. The shaft member has a spray head fastened thereto for rotation of the head with the shaft member. An inner wall of the housing body and an outer portion of the shaft have complementary shapes forming a regulating passage therebetween. The shaft has helical grooves that spiral around the shaft to one or both ends to impart rotation to the shaft and spray head.Type: ApplicationFiled: September 5, 2013Publication date: January 9, 2014Applicant: STONEAGE, INC.Inventor: Douglas E.

Patent number: 8573599Abstract: A unitary cartridge seal assembly for a high pressure liquid sealing connection between two relatively rotatable liquid passage members of a rotary nozzle or a swivel and a tool having such an assembly. The assembly comprises a thimble shaped or cylindrical housing having a flanged retainer fitting within an axial orifice to hold the components together while allowing sufficient axial movement to insure complete sealing of the respective elements. The assembly provides “drop-in” replacement of wearable parts of the rotary face seal of a high pressure water jet blasting tool.Type: GrantFiled: January 15, 2009Date of Patent: November 5, 2013Assignee: Stoneage, Inc.Inventor: Douglas E.

Patent number: 8505845Abstract: A system for storing, rotating and feeding a high pressure hose. A first portion of the hose is disposable about the drum and a guide arm engages a second portion of the hose. An actuator assembly rotates a cage and the guide arm so that the guide arm rotates relative to the cage such that the hose is rotated. Relative rotation in one direction causes the first portion of the hose to uncoil from the drum and displace along the guide arm and causes a third portion of the high pressure hose in an output port to displace out of the output port away from the guide arm. Relative rotation in an opposite direction causes the second portion of the high pressure hose to coil about the drum and causes the third portion of the high pressure hose to displace into the housing.Type: GrantFiled: July 29, 2010Date of Patent: August 13, 2013Assignee: Stoneage, Inc.Inventor: Gerald P.
