    摘要: A member of an element for feeding fluid and pasty products in cylinder or sleeve form, able to withstand high thermal transitions, comprises, arranged concentrically relative to each other, a part made of ceramic material (6, 16) intended to come into contact with the fluid and a support made of polymer material (14, 22) overmoulded on the part made of ceramic material (6, 16). The part made of ceramic material (6, 16) has, on its external lateral face, at least one relief (24) comprising at least one dextrogyral helical groove and at least one levogyral helical groove that extend over the surface of the ceramic part in contact with the support made of polymer material which both prevent any relative movement of this part (6, 16) and of the support (14, 22), and distribute the tensions that can be produced by high temperature differentials.
