Title: Soupape d'arret a detection de debit
Inventor: MARONEY G EARL
IPC: F16L55/10
Filed: 1990-04-13
Abstract: L'invention concerne une soupape d'arrêt à détection de débit 10 pouvant être montée entre des portions amont et aval d'un système hydraulique. Elle comprend un corps de soupape comportant des orifices d'entrée d'alimentation et de sortie de retour 14, 17 pouvant être reliés à la portion amont du système, et des orifices de sortie d'alimentation et d'entrée de retour 15, 16 pouvant être reliés à la portion aval du système. Un élément de soupape 32 à l'intérieur du corps de soupape peut se déplacer entre une position normalement ouverte dans laquelle les orifices d'entrée et de sortie d'alimentation et de retour sont reliés par des passages séparés 24, 25, 26, 27 dans le corps de soupape, et une position fermée dans laquelle les passages sont obturés. Des débitmètres d'alimentation et de retour 40, 42 sont susceptibles de détecter le débit de fluide dans les passages entre l'élément de soupape 32 et l'orifice de sortie d'alimentation 15 et l'orifice de sortie de retour 17, respectivement. Des signaux de débit émanant des débitmètres sont comparés dans un circuit de commande 48 et, en réaction à une certaine différence de débit, un signal de sortie attaque un dispositif d'actionnement 53 qui fait passer l'élément de soupape 32 en position fermée, isolant la portion amont du système hydraulique. Applications notamment dans les systèmes de commande de vol hydrauliques de l'aéronautique.

Title: Device for using gravity to steer a self-contained vehicle travelling through a sloping space
Inventor: JEAN-ANDRE LECHLEITER
IPC: B62D11/04
Filed: 1993-05-19
Abstract: The invention relates to a device for steering a self-contained vehicle intended to travel through a sloping space, in contiguous successive paths in order to complete a cleaning or processing task. The towing assembly includes two reversible electric motors, one for each side of the vehicle. The changes in direction are obtained by unilaterally stopping the traction, as with tracked vehicles. The successive paths take place alternately, ascending and descending, following the line of greatest slope, by the action of a tilt switch which is sensitive to the transverse inclinations of the vehicle. The half-turn and reversal sequences required for controlling the ascent or descent are provided by a multi-function switch actuated by gravity when the slope of the land is sufficiently accentuated at the end of the paths. The device may be particularly intended for steering a beach-cleaning vehicle.
