WIPO Patent Application WO/2017/030168

Kind Code:

A1

Abstract:

This method for forming an operating oil channel in a hydraulic actuator is configured so that a valve-block-mounting surface having first and second areas is formed on an external surface of a housing, valves for a hydraulic actuator belonging to a principal function group are assembled into a principal function valve block that can be directly or indirectly mounted in the first area, valves for a hydraulic actuator belonging to an additional function group are assembled into an additional function valve block that can be directly or indirectly mounted in the second area, and the valve blocks are mounted in corresponding areas of the valve block mounting surface, whereby the equipped hydraulic actuators are fluidly connected so as to be able to be operated by the operating oil from a shared oil source.
