Abstract (en)
The gun comprises a cylindrical bush (4) terminated at one of its extremities by an output nozzle (5), at least one passage communicating with a feed conduit (7, 8) leading the product to be delivered under pressure to the gun, and means of closing off which interact with a trigger (3) in such a way as to control the delivery of the paste product. According to the invention, the said passage (6) is a lateral passage formed in the wall of the cylindrical bush, the means of closing off comprising a cylindrical piston (9) housed in the bush and provided with a calibrated throat (13) opening at one of its extremities towards the output nozzle, this piston being movable with respect to the bush between a completely closed position blocking the lateral passage and a completely open position putting the lateral passage opposite the longitudinal throat, and the straight section of the portion of the calibrated throat (13) situated face to face with the lateral passage varies linearly between the completely closed position and the completely open position. <IMAGE>
