Title
(EN) MILKING MACHINE HOSE
(FR) TUBULURE DE MACHINE A TRAIRE
Abstract
(EN)
A hose (24) constitutes a part of a milking machine and has an end portion (30) which is radially expanded and applied on a tubular nipple (29), the outer diameter of which exceeds the inner diameter of the hose. The milking machine comprises means for providing a negative pressure in the hose. The hose is reinforced by means of at least one elongated reinforcement member (25, 26), which consists of a material substantially harder than the wall of the hose and which extends along the hose in a helical cavity in the wall of the hose. In addition, the reinforcement member completely fills up said cavity and is arranged therein, such that relative movement between the reinforcement member and the wall of the hose is allowed.
(FR)
Tuyau souple (24) faisant partie d'une machine à traire, présentant une extrémité (30) d'un diamètre élargi s'emboîtant sur un embout tubulaire (29) dont le diamètre extérieur est supérieur au diamètre intérieur du tuyau souple. La machine à traire comporte un dispositif permettant d'établir une pression négative à l'intérieur du tuyau souple. Ce dernier est renforcé par au moins un élément allongé de renfort (25, 26), constitué d'un matériau sensiblement plus dur que la paroi du tuyau souple et s'étendant le long de celui-ci à l'intérieur d'une cavité hélicoïdale ménagée dans sa paroi. Par ailleurs, l'élément de renfort occupe la totalité de ladite cavité et se trouve positionné de manière qu'un mouvement relatif entre lui-même et la paroi du tuyau souple est possible.
