Title
(EN) ELECTRO-HYDROSTATIC ACTUATOR
(FR) ACTIONNEUR ÉLECTRO-HYDROSTATIQUE
Abstract
(EN) Embodiments of the present disclosure provide a method and apparatus having an actuator assembly. An exemplary actuator assembly includes a cylinder body having a longitudinal axis and a plurality of passageways, and an accumulator fluidly connected to the plurality of passageways. The exemplary actuator assembly also includes a solenoid assembly comprising a core tube, an armature, a first magnet, a second magnet, and an excitation coil, the core tube extending through the longitudinal axis, the core tube having a first ferromagnetic end section and a spaced apart second ferromagnetic end section.
(FR) Conformément à des modes de réalisation, la présente invention concerne un procédé et un appareil ayant un ensemble actionneur. Un ensemble actionneur à titre d'exemple comprend un corps de vérin ayant un axe longitudinal et une pluralité de passages, et un accumulateur relié de manière fluidique à la pluralité de passages. L'ensemble actionneur à titre d'exemple comprend également un ensemble solénoïde comprenant un tube central, une armature, un premier aimant, un second aimant et une bobine d'excitation, le tube central s'étendant à travers l'axe longitudinal, le tube central ayant une première section d'extrémité ferromagnétique et une seconde section d'extrémité ferromagnétique espacée.
