An assembly for rotating and axially directing a high pressure spray hose and spray head to clean residue from tubing bores. Modular, remotely controlled subassemblies are concentrically aligned and mounted to a hose drive framework to rotate in synchrony and direct a high-pressure water hose and spray head. A hose drive assembly controls hose rotation and axial hose movement via biased pinch wheels. A resilient, eccentric linkage controls pinch wheel pressure. A layering arm uniformly layers th...

A drain cleaning system which utilizes a plumbing cable and nozzle assembly. A fluid-conveying hose is incorporated within a plumbing cable and a nozzle is affixed to the distal end of the cable and in communication with the hose. The nozzle includes a body having a rounded radius tip and a rotatably mounted ring having a plurality of radial jet passages formed therein. The ring and the body cooperatively define an annular passage therebetween. Pressurized water passes through the nozzle body an...

There is mentioned a process and an arrangement for cleaning of pipelines, and especially ventilation pipes and ventilation ducts in buildings, by means of a largely spherical cleaning means (1) which is connected via a supply conduit (2) with a source of pressure medium, and which exhibits a nozzle opening in the form of a largely continuous annular gap (6) which extends along the periphery of the cleaning means (1) and which is connected to the supply conduit (2) and the source of pressure med...

There is a disclosed a cleaning for a medical instrument, including a nozzle main body detachably to a surgical ultrasonic treatment instrument including a channel, and the nozzle main body includes a water supply port opened in a position connected to the channel, when mounted in the surgical ultrasonic treatment instrument.

Fluid jet apparatus and method for cleaning material from the inside of a tubular conduit utilizing a cleaning head that lies adjacent to one wall of the conduit and includes at least two fluid jet forming means for directing a plurality of high pressure fluid cutting jets in a forward direction and at an acute angle relative to the axis of the head and the conduit so that they are directed toward the opposite wall of the conduit. The cleaning head is rotated around and remains adjacent to the w...

The device comprises a ramp for dislodging sludge by high pressure jets fixed permanently inside a steam generator, horizontally and above the tube plate. The ramp is supplied with water under pressure through a movable distributor. The device also includes means for driving the sludge towards the center of the plate and a discharge valve for the sludge arranged above an orifice passing through the tube plate at its central part and opening into the hollow central column. The invention is partic...

A collapsible pig attached to the end of a tubing and having a seal to the bore of a pipeline for pulling the tubing into the pipeline at up to a predetermined pressure differential across the seal and while allowing the fluid in front of the pig to flow into the end of the tubing without pressure restriction, alternately having reversed flow from within the tubing exit the end of the tubing through jetting nozzles, and having the seal collapse at a pressure differential higher than the predeter...

Device (11) for driving a flexible lance (4) for cleaning a heat exchanger duct, provided with a frame (1) in which a drive (12) driving a flexible lance (4) is arranged for moving this flexible lance (4) in the direction of an outlet opening. The drive (12) is provided with a member (27) which can be clamped round the flexible lance (4) and which is movable in the frame (1) towards and away from this outlet opening.

A method and a device for washing a drain pipe allowing a nozzle to be rotated along the inner peripheral surface of a pipe even in a lateral pipe, wherein the positions of a plurality of injection holes (10, 11, 12, and 13) formed in the nozzle (1) are formed and the amount of high pressure water jetted from each of the injection holes (10, 11, 12, and 13) are regulated so that the specific injection hole (10) only among the plurality of injection holes is set so as to be opposed always to the ...

An assembly for rotating and axially directing a high pressure spray hose and spray head to clean residue from the bores of thermal transfer tubes. The assembly includes a number of subassemblies that are concentrically aligned and mounted to rotate in synchrony and direct a high-pressure hose and spray head. A hose cleaning subassembly washes and/or brushes the hose exterior with a low-pressure spray. A hose drive assembly controls axial hose movement via driven gears and chains and four polyur...
