Definitions

  • the invention relates to an insert element (diesel agent) to be installed in the filling opening of a container intended for diesel fuel, and to a fuel container itself, which is provided with elements of the insert element in Integralbauweise.

  • a cross-sectional dimension on its free end side is smaller than the inner diameter of an outlet tube of a diesel nozzle, however, is larger than the inner diameter of a petrol nozzle -Auslaufrohres.
  • the holding member is thereby formed with respect to its outer periphery so that it can be fixed in the opening of a filler neck regardless of its clear width in a press fit.
  • This can be made possible by the outer circumference of the holding element is conically shaped, so that the holding element at the inlet side of the diesel has a larger outer circumference, as compared to its outlet end. The holding element is therefore pushed so far into the filler neck until it is locked with its outer periphery at the opening plane of the filler neck.
  • the retaining element advantageously has at least one spring slot along the longitudinal axis of the retaining element on its outer circumference, by means of which the retaining element can be pressed together in the outer circumference, the outer circumference is thus variable in an elastic manner.
  • the insert element can always safely sink in the filler neck even with different opening sizes of filler neck, it always closes regardless of the opening width from the filler neck, and it does not protrude beyond the filling opening. Due to this fact, then the lid of the filler neck can be locked again after insertion of the insert element on the filler neck.
  • the spring slot should not be made over the entire length of the retaining element, since at the lower end of the retaining element is the actuating element, which should have a tight fit in the retaining element, so that the retaining element should provide a stable, ie un deformable seat for the actuator, in which seat the actuator can be moved over a predetermined distance (see later).

Abstract

L'invention concerne un élément d'insertion (13) pour un réservoir de carburant diesel, qui peut être installé dans l'orifice de remplissage (10) du réservoir, en particulier dans une tubulure de remplissage, afin de faire le plein de carburant diesel avec un pistolet de distribution dans une station-service. L'élément d'insertion (13) comporte un élément de retenue (16) allongé, de forme sensiblement tubulaire, pouvant s'ajuster dans l'orifice du réservoir, et muni d'un côté entrée et d'un côté sortie, dans lequel est retenue une pièce moulée (18) allongée parallèlement à l'élément de retenue (16). La face avant libre de la pièce moulée faisant saillie en direction du côté entrée présente un diamètre extérieur qui est d'une part inférieur au diamètre intérieur d'un tube de sortie (12) d'un pistolet de distribution de diesel mais qui est d'autre part supérieur au diamètre intérieur d'un tube de sortie d'un pistolet de distribution d'essence. Par ailleurs, sur la paroi intérieure de l'élément de retenue (16), en direction de l'orifice de remplissage, est agencé un élément d'actionnement coulissant coaxialement qui est retenu derrière la face avant de la pièce moulée (18) en direction du côté intérieur du réservoir. Cet élément d'actionnement, lorsqu'il est déplacé en direction de l'intérieur du réservoir, peut actionner un clapet de fermeture qui est agencé sur le côté sortie de l'élément de retenue (16). L'invention est caractérisée en ce que le clapet de fermeture est constitué de deux moitiés de clapet, qui peuvent pivoter respectivement par rapport à l'axe longitudinal de l'élément de retenue à l'intérieur de ce dernier afin d'amener l'élément d'insertion en position d'ouverture.
