SYSTEME HYDRAULIQUE A COMMANDE ELECTRIQUE ET TRANSDUCTEUR POUR CELUI-C

摘要

Hydraulic system in which the application of fluid to a cylinder is controlled electrically by circuitry connected to an elongated resistance element mounted within a hydraulic cylinder and to a slider contact carried by a piston within the cylinder. The resistance element is part of a first assembly supported from one end of the cylinder and extending within a passage within a piston rod and is wound on and connected at a first end to a metal rod disposed in a longitudinal slot of an insulating support. A second metal rod is in a diametrically opposed slot and is engaged by a second slider contact, the contacts being part of a second assembly and being at the ends of resilient arms supported within the tubular insulating member which is mounted within the open end of the piston rod passage. Terminal means are connected to the metal rods and to a second end of the resistance element at one end of the first assembly which is at one end of the hydraulic cylinder.
