Method and system for air spray coating and manually-operated atomizing device for use therein

摘要

A manually-operated air atomizing device includes a trigger- operated valve which generates pneumatic control signals. The atomizing air, fan air and fluid supply are varied according to the position of the trigger. A set of preprogrammed valves control the proportion of atomizing air, fan air and fluid delivered to the atomizing device in response to the pneumatic control signals.
