Document Type and Number:
WIPO Patent Application WO/2023/128016
Kind Code:
A1
Abstract:
The present invention relates to an oil-flushing apparatus, for an electro-hydraulic control actuator, having a structure in which a first body, having first to fifth flow paths, a detection flow path and a test-point coupling, and a fluid pressure generation part are connected, and a high-pressure flushing guide part is disposed selectively or at all times on a pipe between the first body and the fluid pressure generation part. Therefore, operational conveniences can be provided such as enabling the oil-flushing apparatus to be easily and detachably attached to a servo actuator and separated therefrom after oil-flushing, and normal operation to resume when the servo actuator and fluid pressure generation part are reconnected.
