Document Type and Number:
Japanese Patent JP6170755
Kind Code:
B2
Abstract:
An electro hydrostatic actuator includes a single-rod cylinder having fixed and movable ends, a hydraulic supply source, and a reservoir provided in a hydraulic circuit and capable of storing operation oil. At a predetermined position of the single-rod cylinder close to the fixed end, the hydraulic supply source is disposed at the periphery of the single-rod cylinder, and is integrated with the single-rod cylinder. The reservoir is formed in a double cylindrical shape, and is, at a position close to the movable end relative to the hydraulic supply source, integrated with the single-rod cylinder in the state in which the single-rod cylinder is inserted into the reservoir so as to be coaxial with the reservoir.
