  • Spraying bowl, rotary sprayer incorporating such a bowl and spraying installation incorporating such a sprayer
    Patent number: 7452421
    Abstract: The bowl according to the invention is equipped with first magnetic coupling means adapted to cooperate with second complementary magnetic coupling means fixed on a non-rotary part of a sprayer, these first and second coupling means being adapted to exert an at least partially axial effort inducing the coupling in rotation of the bowl with a corresponding drive member. The radial width of an annular or truncated surface defined by the first coupling means is greater than the total radial width of the coupling means borne by the non-rotary part.
    Type: Grant

  • Manually controlled spraying installation and sprayer
    Patent number: 4998672
    Abstract: An installation for spraying a coating product includes a manually controlled pneumatic sprayer operated by a trigger. The compressed air flowrate is varied according to the position of the trigger. The coating product feed system can include a gear pump driven at variable speed by a motor controlled by an electric signal representing the position of the trigger.
