The descaling device has an improved maintainability and reliability due to the descaling device having a motor, and due to the motor being arranged on the shaft in the device housing between the nozzle head and the medium coupling in order to generate the rotary movement of the shaft.

The washing nozzle for washing an inside of the machine tool with fluid includes a base portion having a tubular passage inside thereof, a supply port through the tubular passage, and a rotary member rotatable about an axis parallel to a surface on which the base portion is mounted, the rotary member having inside thereof a nozzle jet port and a nozzle flow passage allowing communication between the tubular passage and the nozzle jet port, wherein the jet port is formed so that fluid jetted from the jet port of the rotary member hits the surface on which the base portion is mounted and the jet of the fluid causes the rotary member to rotate about the parallel axis.

A lance nozzle injecting fluid includes a shaft body, a first nozzle hole, and a second nozzle hole. The shaft body internally includes a flow path of the fluid. The first nozzle hole is disposed on a leading end side of the shaft body, and generates a first jet in a first injecting direction inclining to a base end side of the shaft body with respect to a direction perpendicular to an axial direction of the shaft body. The second nozzle hole is disposed on a base end side of the first nozzle hole in the shaft body, and generates a second jet in a second injecting direction inclining to a leading end side of the shaft body with respect to a direction perpendicular to an axial direction of the shaft body.

A method for preserving cavities by applying a protective layer to the interior of a hollow body. The method uses a mixing nozzle unit coupled to a rotor unit. The mixing nozzle unit is rotated about an axis of rotation and has a mixing nozzle. The mixing nozzle unit has two supply channels for the cavity preservative and for gas for atomizing the cavity preservative. The supply channels run in the direction of the axis of rotation and conduct cavity preservative and atomizing gas separately to the mixing nozzle. The mixing nozzle unit is inserted into the hollow body in the direction of the axis of rotation through an opening in the hollow body. The cavity preservative is discharged in atomized form, and the mixing nozzle unit is rotated about the axis of rotation relative to the hollow body during the discharging or between a plurality of discharging phases.

A high pressure nozzle, including a longitudinal housing, with an internal channel therein, a nozzle head support shaft, which is rotatably arranged partially in the internal channel, a rotary nozzle head, which is attached to the nozzle head support shaft and arranged outside the housing, and an axial bearing seat, which is located within the housing and which comprises an axial bearing surface that faces an end surface of the nozzle head support shaft. The axial bearing surface and the support shaft end surface, during use, cooperate to form an axial bearing for the nozzle head support shaft and the axial bearing seat includes an axial bore in the axial bearing surface that is aligned concentrically with an axis of rotation of the nozzle.

A high-pressure jet apparatus having a simplified structure includes: a nozzle rotation shaft penetrating a nozzle head, disposed in the nozzle head in a rotatable manner, and including a first flow passage penetrating the nozzle rotation axis; a swivel joint disposed at a proximal end of the nozzle rotation shaft, and connected to the first flow passage; a spindle housing disposed on the nozzle head; a spindle supported by the spindle housing, connected to a distal end of the nozzle rotation shaft, rotatable integrally with the nozzle rotation shaft, and including a flange located at a distal end of the spindle, and a second flow passage penetrating the spindle to be connected to the first flow passage, a nozzle including a first nozzle outlet connected to the second flow passage, and connected to the flange; and a transmission unit that transmits rotation of the nozzle rotation shaft to the spindle.
