Abstract

La solicitud se refiere a una unidad cilindro-émbolo de un inyector con un cilindro y un émbolo guiado en el mismo, donde el cilindro y el émbolo rodean una cámara que puede cargarse como mínimo temporalmente con principio activo y el cilindro presenta en su superficie frontal anterior como mínimo una escotadura de salida. La superficie frontal anterior del cilindro de la unidad cilindro-émbolo es una superficie espacial de curvatura convexa, cuyo canto anterior debe asignarse como mínimo a una escotadura de salida. Con la presente solicitud se desarrolla una unidad cilindro-émbolo que garantiza un manipuleo sencillo y seguro.The request refers to a cylinder-piston unit of an injector with a cylinder and a guided piston therein, where the cylinder and the piston surround a chamber that can be temporarily loaded with active principle at least and the cylinder has on its front surface previous at least one exit recess. The front front surface of the cylinder of the cylinder-piston unit is a spatial surface of convex curvature, whose leading edge must be assigned at least to an outlet recess. With the present application a cylinder-piston unit is developed that guarantees simple and safe handling.
