Abstract:
(EN) A sealing material discharge device, which discharges sealing material inside a cylindrical cartridge from a nozzle provided at the tip of the cartridge, is provided with: a plunger that tightly seals the sealing material inside the cartridge and is movable in the axial direction of the cartridge; a piston that has a through hole passing through in the axial direction and is capable of applying pressure on the plunger toward the tip end side of the cartridge; and a suction means for sucking the plunger to the piston side via the through hole in the piston. Thus, it is possible to favorably suppress dripping when stopping the discharge of the sealing material.
(FR) L'invention concerne un dispositif d'éjection de matériau d'étanchéité, qui éjecte un matériau d'étanchéité à l'intérieur d'une cartouche cylindrique par une buse placée à l'extrémité de la cartouche, qui comporte : un poussoir qui renferme hermétiquement le matériau d'étanchéité à l'intérieur de la cartouche et est mobile dans la direction axiale de la cartouche ; un piston qui comporte un trou de passage traversant dans la direction axiale et est capable d'appliquer une pression sur le poussoir vers le côté d'extrémité de pointe de la cartouche ; et un moyen d'aspiration pour aspirer le poussoir vers le côté piston par l'intermédiaire du trou de passage dans le piston. Ainsi, il est possible de supprimer favorablement l'égouttement lors de l'arrêt de l'éjection du matériau d'étanchéité.
(JA) 筒状のカートリッジ内のシーリング材をカートリッジの先端に設けられたノズルから吐出するシーリング材吐出装置において、カートリッジ内にシーリング材を封止すると共にカートリッジの軸方向に移動可能なプランジャと、軸方向に貫通する貫通孔を有すると共にプランジャをカートリッジの先端側に押圧可能なピストンと、ピストンの貫通孔を介してプランジャをピストン側に吸引する吸引手段と、を備える。これにより、シーリング材の吐出を停止する際のキレを良好にすることができる。
