The trigger-operated spray unit consists of a pump with a trigger, valve and adjustable nozzle which fits on top of a container of the fluid to be sprayed. The nozzle, which has a rotary tip (38) to control the spray jet, contains an element (45) with a series of feed channels, two of which are of the same size, while the third is slightly larger, and are located along radial lines at an angle of 120 deg. to one another. The element is linked by strip springs (54) to the valve (53) which covers the end of the pressure channel from the trigger-operated pump. The pump is in the form of a cylindrical chamber, containing a piston, with the pump housing forming a set for the valve at the end of the pressure channel. |
