Patent

CA 2340861

An aerosol spray gun used selectively in two spraying modes of small pattern and large pattern and is provided which can be comprised of simple components. Aerosol spray gun 1 includes a throttle valve mechanism 35, an air duct 43, and a coupling link 45. The throttle valve mechanism 35 is provided in an internal air duct 23 for supplying pressurized air to a patterning air outlet 21 which shapes a paint spraying stream jetted out from the aerosol spray gun 1, and it has a movable valve element 39 to which a compressed spring 41 applies force to open the valve. The air duct 43 created at the tip of the movable valve element 39 supplies a small volume of air from the internal air duct 23 to the patterning air outlet 21 while the movable valve element 39 seats on a value seat 37. The coupling link 45, coupling the movable valve element 39 to the trigger 7, is provided with an elongated hole 47 to disconnect the trigger 7 from the movable valve element 39 without cooperative relation between them from an initial stage where an operator begins to squeeze the trigger 7 to an intermediate stage before the operator fully squeezes the trigger.
