A desk type liquid chemical spraying device, or a desk type liquid chemical spraying device, sprays a liquid chemical in a wide range. The spraying device includes a plurality of nozzles for spraying the liquid chemical to an upper side of a spraying case through a nozzle structure and spraying the liquid chemical to four sides while a nozzle structure is rotated so that the liquid chemical spraying device may be located in a flat place such as a ground surface or a desk.

Sealing system of a device for allowing the passage of a medium, in particular in the high pressure range, is provided with a housing that has a bore hole, a component mounted within the housing such as to oscillate and/or rotate and with a pressure chamber formed within the bore hole. A sealing element surrounding the component adjoins this pressure chamber which can be charged with the medium. An additional metal seal is formed here by the housing and a pressure disc surrounding the component. The outer region is thus tightly closed after the sealing element. In this way, the sealing element is completely tightly encapsulated on the outside.

The present invention relates generally to an improved rotating lawn sprinkler capable of precisely watering lawns with straight edges without over-spraying onto sidewalks and fences. More specifically, the invention relates to a rotating sprinkler with a plane of rotation is adjustable upwards or downwards from horizontal that will water in a triangle pattern when the plane of rotation is angled downwards from horizontal or a diamond pattern when the plane of rotation is angled upwards from horizontal. These watering patterns are possible because the axis of rotation is adjustable, which adjusts the plane of rotation. By adjusting the plane of rotation, the nozzle trajectory is being continually increased or decreased as the sprinkler rotates, which causes the watering pattern to form patterns with straight lines rather than traditional watering arcs.

A high pressure surface cleaner includes a housing having an open end, a high pressure coupling in fluid communication with the housing and having a first end and a second end, the first end configured to receive a high pressure water source, and a supply conduit rotatably secured to the second end of the high pressure coupling and configured to rotate about the high pressure coupling defining a horizontal plane within the housing. The cleaner also includes first and second nozzles having a vertical axis therethrough and secured proximate to the first and opposing second ends of the supply conduit, respectively, the vertical axis of the first and second nozzles approximately normal to the first horizontal plane, and a directional nozzle coupled to the supply conduit and having a directional outlet orientated to cause the supply conduit with the first and second nozzles to rotate when discharging water.

A rotating cleaner (1) comprising a housing (2) which has a cavity (10) and an inlet (9) which is connectable to a fluid supply line, a shaft (5) extending in sections into the cavity (10), a sprayer body (3) which is non-rotatably connected with the shaft (5) and has an outlet (8), and further comprising a sliding bearing for rotatably supporting the shaft (5) in the housing (2), said sliding bearing having a rotating bearing surface (23), an idle bearing surface (22) and a bearing gap. To improve the cleanability and the rotational characteristics of the rotating part, it is proposed that the rotating bearing surface (23) and the idle bearing surface (22) are each formed as a contiguous surface for supporting the shaft (5) in the radial and axial direction.

The present invention introduces an operational end module for material spraying or working tool applications. The end module may be fixed in an arm. The end module senses its current location and alignment, together with its nearest distance to an obstacle. The system corrects the direction and location of the end module based on the sensed data and the used application. The device has a user input interface and a screen for parameter representation. The end module direction and location can be controlled by three mutually orthogonally aligned motors connected along the material pipe, where the pipe curves between the motors, together with a variable length arm. A machined screwdriver operation in difficult locations is an example of the invention in the area of working tools.

A bearing assembly suitable for a fluid delivery system such as a hydraulic water cannon, including for a first pipe that is moveable relative to a second pipe, the assembly comprising a main body adapted to be connected to an end of the first pipe, an annular centre swivel adapted to be connected to an end of the second pipe, the centre swivel including an annular, axially extending boss extending away from the main body, with the opposed radially extending face extending radially outwardly from said boss, and a bearing end cap adapted to engage around the second pipe and be fastened to the main body securing there between said centre swivel. The bearing assembly is adapted to operate at water pressures greater than 10 bar.
