Patent FR-2668722-A1 (FR)
Title: Mechanism for driving and for positionally controlling a long thin element, such as the rod for positionally actuating the needle of the nozzle of a spray gun
Inventor: GASTON BAYOURTE
IPC: B05B12/00
Filed: 1990-11-06
Abstract: The mechanism according to the invention comprises an electric motor (12) driven under voltage, to the output shaft of which is fastened a first plate (13) provided with guides (15) on which is slidably mounted a second plate (14) solidly attached to the rod (1) for actuating the needle (2) of the nozzle (3). Between the plates (13) and (14) are arranged a compression spring (16) and two weighty deformable systems (17), of equal masses, which deformable systems are deformed by moving apart when the plates are rotated. Resulting from this deformation is a traction force exerted on the plate (14), which moves the needle (2) into the nozzle (3). The position of the needle depends on the speed of rotation of the motor and this position is controlled by a Hall-effect cell (22) associated with a magnet (23).
