ABSTRACT:
A simple, two-part adjustable spray device is disclosed, the device consisting of a tubular member within which is a cylindrical insert member. At its inner end, the insert member includes a chamber in selective communication with both the inlet portion of the tubular member and a longitudinal channel formed in the internal wall of the outlet portion of the tubular member. The side wall of the insert member defining the chamber is sufficiently flexible to be distended by the pressure of liquid within the chamber into a sealing engagement with the interior side wall of the tubular member. By rotationally adjusting the insert member, the chamber may be brought into selective communication with the longitudinal channel to allow a varying volume of liquid to pass from the inlet to the outlet and a spray of liquid to be emitted through a profiled aperture. The tubular member and the insert member may include interlocking shoulders with serrations to hold the insert member in a multiplicity of rotational positions within the tubular member.
