The second tip is arranged behind the first tip.

A method of reducing water flow through a showerhead. The method may include dividing a water stream into two separate water groups and alternating the flow of water through the two separate water groups to reduce water flow through the showerhead.

A spray bar injector including a spray bar defining a longitudinal axis and including a fluid inlet and a plurality of spray outlet orifices spaced apart longitudinally in a direction along the longitudinal axis. A check or spray valve is operatively connected to each spray outlet orifice. A master valve is in fluid communication with the fluid inlet, operatively connected to divert flow from the fluid inlet into a first passage and block flow into a second passage in a first position to open the check valves and issue a spray from the spray outlet orifices, and to divert flow from the fluid inlet into the second passage and block flow into the first passage in a second position to close the check valves and block issue of spray from the spray outlet orifices.

An applicator for a coating product comprising printing nozzles, each including an outlet channel emerging in the downstream direction by a coating product discharge orifice. The printing nozzles are distributed on at least two faces of a body of the applicator and the discharge orifices of these nozzles extend along at least two nonparallel planes.

Due to the dynamic mechanical loads to which motor vehicle traction batteries are subjected, housings of battery cells of the traction batteries are covered at least in part by an electrically insulating layer made from a coating material. For this purpose, a method and a coating station for carrying out the method are proposed. The method is performed with a liquid electrically insulating coating material, by applying separately produced individual drops of the coating material using a coating applicator. The drops form coating points on an outer surface of the housing, which coating points are applied sequentially with the coating applicator, adjacently to one another or overlapping, so that together they form coating lines.

A method for emitting a fluid from an aerial fluid dispersal system includes emitting the fluid from a plurality of individually controlled nozzle assemblies distributed across a manifold assembly. The method also includes receiving, at a controller, an input associated with a desired droplet size of the fluid emitted from each respective nozzle assembly and determining, by the controller, a target differential fluid velocity for each respective nozzle assembly based on the desired droplet size. The method also includes regulating, using the controller, the velocity of the fluid exiting each respective nozzle assembly to produce the target differential fluid velocity from each respective nozzle assembly.
