Abstract: In all areas of the hydraulic control and regulation technology, check and shut-off valves that react quickly and without delay are required. With such valves, the dynamic properties of fuel injection systems could also be considerably improved, and their design could be simplified. An electrohydraulic check device with a simple and compact structure is disclosed that works in a reliable manner even at high actuation frequencies (f > 1 kHz) and ensures shut-off times in a range  tau  lower than 0,1 ms. The check device has a piezoelectric actuator (P) that acts on two mutually coupled hydraulic alternating transformers with identical reduction ratios. The essential components of the check device are a pressure piston (DK) driven by the actuator (P), an alternating piston (HK) axially movable in a cylindrical bore (ZY) of the pressure piston (DK) and a chamber (KB) into which open supply and outflow channels (B2, G2, B3, G3) for the medium to be shut-off. By controlling the actuator (P), the dumbbell-shaped alternating piston (HK) may be moved practically without delay in the pressure piston bore (ZY), closing the supply or outflow channels (B2, B2). The invention has application in check and shut-off valves, as well as in fuel injection systems.

Abstract: Pour conférer, d'une manière simple et économique, une structure colorée à une feuille extrudée ou coextrudée, on ajoute un agent moussant dans au moins une couche de la feuille, avant l'extrusion du mélange hétérogène de matières plastiques colorées et transparentes ou de couleur différente, on chauffe le mélange jusqu'à une température supérieure à la température de ramollissement de la matière plastique, l'agent moussant étant simultanément au moins en partie activé, et on procède ensuite à une extrusion en maintenant au moins en partie l'hétérogénéité. L'addition d'un agent moussant empêche au moins en partie la formation d'un mélange homogène des matériaux en matière plastique. De ce fait, la feuille extrudée présente, par exemple, des zones transparentes (4) et des zones colorées (3) séparées des premières dans la couche (12). Les zones transparentes (4) laissent voir la couche (10) sous-jacente de couleur différente. On peut ainsi obtenir une variété de structures colorées. L'emboutissage pour la formation de gobelets ou d'assiettes a pour effet de déformer ces zones transparentes (4) ainsi que les zones colorées (3), ce qui modifie la structure.
