Abstract:
(EN) This barrel assembly (10A) is provided with a barrel (12), a gasket (14) and a plunger (16). A rotation preventing groove (20) provided on one among the gasket (14) and the plunger (16), and a rotation preventing projection (21) provided on the other among the gasket (14) and the plunger (16) are engaged to prevent the relative rotation of the gasket (14) and the plunger (16). A first rib (30) formed on the gasket (14) and a second rib (31) formed on the plunger (16) are engaged to prevent the plunger (16) from being separated from the gasket (14).
(FR) La présente invention concerne un ensemble cylindre (10A) pourvu d'un cylindre (12), d'un joint d'étanchéité (14) et d'un piston (16). Une rainure de prévention de rotation (20) disposée sur un élément parmi le joint d'étanchéité (14) et le piston (16), et une saillie de prévention de rotation (21) disposée sur l'autre élément parmi le joint d'étanchéité (14) et le piston (16) sont en prise pour empêcher la rotation relative du joint d'étanchéité (14) et du piston (16). Une première nervure (30) formée sur le joint d'étanchéité (14) et une seconde nervure (31) formée sur le piston (16) sont en prise pour empêcher le piston (16) d'être séparé du joint d'étanchéité (14).
(JA) バレル組立体(10A)は、バレル(12)と、ガスケット(14)と、押し子(16)とを備える。ガスケット(14)及び押し子(16)の一方に設けられた回転防止用溝(20)と、ガスケット(14)及び押し子(16)の他方に設けられた回転防止用突起(21)との係合により、ガスケット(14)と押し子(16)との相対回転が防止される。ガスケット(14)に設けられた第1リブ(30)と押し子(16)に設けられた第2リブ(31)との係合により、ガスケット(14)からの押し子(16)の離脱が防止される。
