An element of a fluid dosing element and pasty products in the form of a cylinder or sleeve, able to withstand substantial thermal transitions comprises, arranged concentrically with respect to each other, a portion of ceramic material ( 6, 16) intended to come into contact with the fluid and a support of polymer material (14, 22) overmolded on the part of ceramic material (6, 16). The part made of ceramic material (6, 16) bears, on its external lateral face, reliefs (24, 26) which, at the same time, prevent any relative movement of this part (6, 16) and the support (14, 22). ) and distribute the voltages that can occur during large temperature differences. |
