Air inlet pipe for paint sprayer has annular wall with cross slit and swivel mounted throttle element with disc part for partially blocking or releasing bore according to position of throttle
the air inlet pipe has an annular wall (4) with cross slit extending at least partially over the internal bore. The throttle element (3) is swivel mounted in the slit and is sufficiently thick to block air outlet from the slit. The throttle element has a disc part(17) which partially blocks the bore when the throttle element is in one position. The disc part has an opening which partially or completely releases the bore when the throttle element is in another position. Stops (15)such as an edge collar are provided to restrict the swivel movement of the throttle element.
