Proposed is a seal for high pressure water jets, the high pressure water jets each includes a housing, a connector through which high pressure water is introduced, a rotary body exposed in a direction in which the high pressure water inside the housing is discharged, a rotary support for supporting the rotary body, a nozzle connected to an end of the rotary body, a shaft, a bushing, and a seal coupled to the outer circumferential surface of the shaft and having a surface in close contact with the bushing, wherein the seal includes an outer seal provided with a through hole having a tapered portion inclined so that the inner diameter thereof is expanded in the direction in which the high pressure water is discharged, and an inner seal inserted in the tapered portion of the outer seal and having the same inner diameter as that of the through hole.

A rotary tank assembly is provided for a liner. The liner is structured to apply a compound to a plurality of container closures. The rotary tank assembly includes a compound tank, a fill tube structured to fill the tank with a volume of said compound to a desired level, a sensor assembly adapted to measure the level of said compound within the compound tank, and a rotary union assembly structured to pivotally couple the fill tube and the sensor assembly to the compound tank. The sensor assembly only requires one single probe.

A multi-mode sprinkler adjustable for part or full circle operation to irrigate a selected area is provided. The sprinkler includes a nozzle for dispensing fluid, a set of gears for rotating the nozzle and an arc setting mechanism that cooperates with the set of gears. The arc setting mechanism comprises a fixed trip for switching to a first direction for the nozzle and an adjustable trip movable relative to the fixed trip for setting an arc of rotation for the nozzle in the part circle mode. The arc setting mechanism also includes a toggle for engaging the fixed trip and the adjustable to switch between a first direction and a second direction when in the part circle mode. In the full circle mode, the adjustable trip overlaps at least in part the fixed trip, such that the fixed trip deflects the toggle radially inward, allowing continuous rotation of the nozzle.

A blasting device has a spray unit for spraying blasting agent onto the surface to be treated. The spray unit has an insert 23′ in which a nozzle 13′ is rotatable. This nozzle 13′ is provided with a number of spray channels 19′ which are at an angle 21′ relative to the supply direction 17 of the blasting agent. The blasting agent is pressed through the spray channels 19′ under pressure and exerts a force on the wall of the spray channels 19′ causing the nozzle 13′ to rotate. The jets emerging from the rotating nozzle 13′ will make a rotating movement. The joint area of the cross-sections of the spray channels 19′ is larger than one third of the cross-sectional area of the circular-cylindrical part of the nozzle. The angle 21′ at which the spray channels are located with respect to the supply direction 17 of the blasting agent is greater than zero and less than 10 degrees.

A robotic fountain is proposed. The robotic fountain includes: a water supply pipe rotating while passing through upper and lower surfaces of a main body of the fountain; a fastening part formed between the lower surface of the main body and a lower end of the water supply pipe; a first motor configured to rotate the water supply pipe; a support part formed between the upper surface of the main body and an upper end of the water supply pipe; a bypass body fastened to the top of the water supply pipe; a through hole formed through one side of a lower surface of a rotary body, the rotary body fastened to an upper surface of the bypass body; an intermediate pipe configured to rotate inside the rotary body; a second motor for rotating the intermediate pipe; and a nozzle formed at the center of the intermediate pipe.

An ultra-high pressure nozzle comprises a stator with a stator channel and a rotor with a rotor channel. A transition from the stator channel to the rotor channel is achieved by a seal, which comprises a rotor bearing hollow body with a rotor bearing channel crossing it in a longitudinal direction and a stator bearing hollow body with a stator bearing channel crossing it in a longitudinal direction. The rotor bearing hollow body is in a fixed location and protrudes into the rotor channel and the stator bearing hollow body is in a fixed location and protrudes into the stator channel. The rotor bearing hollow body and the stator bearing hollow body do not overlap each other. When the nozzle is mounted, the front surface of the rotor bearing hollow body rests in direct contact with a front surface of the stator bearing hollow body in a rotatable manner, thereby creating a seal.
