Abstract: An actuator for a spray valve is provided which includes an actuator head and spray producing body positioned within the head. The actuator head includes a mechanism for connecting the head to a spray valve and transfer channel for receiving a pressurized fluid from the spray valve. The transfer channel is formed with a terminal area surrounding an outlet orifice of the channel. The spray producing body is positioned against the terminal area and has a front wall distant therefrom. The spray producing body features a swirl chamber situated adjacent the outlet orifice, a first channel downstream from the swirl chamber, a second channel of narrower diameter and downstream from the first channel, an expansion orifice situated further downstream and at least four unconnected dead-ended recesses formed into the front wall and surrounding the expansion orifice.
