A method and apparatus for applying a fluid onto a number of surfaces. The apparatus comprises a structure, an applicator associated with the structure, a first control device associated with the structure, and a second control device associated with the structure. Applying a first force to the first control device causes the applicator to move relative to a center axis of the applicator. Applying a second force to the second control device causes the fluid to be delivered from a fluid dispensing system to the applicator.

The invention is directed at systems and methods which provide for effective cleaning and drying of vehicles of different shapes and sizes. The invention in one example includes a vehicle washing apparatus comprising a conveyor system to move a vehicle along a path, and a bridge assembly supported above a vehicle and moveable along the length thereof. At least one trolley assembly is operatively supported by the bridge assembly and is moveable in a direction generally transverse to the movement of the bridge assembly. At least one cleaning arm assembly for delivering cleaning fluid to or for brushing the surface of a vehicle is operatively supported by the at least one trolley assembly or bridge. The cleaning arm assembly is moveable with the bridge assembly along the length of the vehicle, and transversely with the at least one trolley assembly to adjust the location of the cleaning arm relative to the vehicle, wherein the bridge assembly moves in association with movement of the vehicle to position the cleaning arm assembly adjacent at least a portion of the front, sides and rear of the vehicle as it moves along the path. A variable impact or patterning spray arm or drying system is also provided.

A dishwasher includes a tub at least partially defining a treating chamber and a sprayer for spraying liquid to the treating chamber. The sprayer may include a liquid passage provided in the interior of the body, at least one upper outlet extending through the upper surface of the body and in fluid communication with the liquid passage, at least one lower outlet extending through the lower surface of the body and in fluid communication with the liquid passage, and a valve body moveable relative to the body to fluidly couple the at least one upper outlet and the at least one lower outlet to the liquid passage.

An apparatus for producing prills includes a hollow body rotatable about a first axis, the body having a wall rotationally symmetrical around the first axis forming an interior space, the wall including nozzles for generating jets of liquid in a radially outward direction with respect to the first axis when rotating the hollow body; a second body disposed in the hollow body forming a gap between the hollow body and the second body; a liquid inlet for supplying a flow of liquid to the gap; a rotary drive unit for driving the hollow body around the first axis; a reciprocating drive-unit for reciprocally moving the hollow body and/or second body with respect to the other body along the first axis of rotation for applying reciprocal pressure on the jets; and a coupling for enabling relative rotations between the one of the hollow body and second body and the reciprocating drive-unit.

A device for discharging a disinfecting solution to disinfect surfaces is configured to be arrangeable on a carrier surface and includes an exchangeable receptacle (39) for receipt of the disinfecting solution, a housing enclosing the receptacle, a spray head (30) configured to discharge disinfecting solution from the receptacle, and a pumping equipment for transporting disinfecting solution from the receptacle to the spray head and for discharging the disinfecting solution from the spray head. In another aspect, there is provided a spray including an inner nozzle part (50) and an outer nozzle part (51). The inner nozzle part includes a first channel for conducting disinfecting solution to a liquid outlet and a second channel for conducting pressurized air to an air outlet. The outer nozzle part includes a spray outlet and encloses the inner nozzle part to form a space between the air outlet und the spray outlet. The liquid outlet is arranged in the space to mix liquid, in particular disinfecting solution, ejecting out of the liquid outlet with pressurized air.

The present disclosure provides an automated dispenser and spray device configured to apply a cleaning solution to a user's body in an automated fashion as they take a shower, freeing their hands. The device comprises an oscillating arm assembly of adjustable height with a spray nozzle at the end. Various parameters of the spray can be adjusted to a user's preferences via a control module and interface so that they can simply focus on cleaning themselves as the solution is applied.
