Multi-functional valve |
摘要 |
A hydraulic system having a high-pressure differential cylinder implemented as a servo actuator is hydraulically connected to a valve combination and an electro-hydraulic servo valve. The valve combination is a multi-functional valve including multiple interengaging valves and correcting elements all disposed within a housing. The valves and correcting elements are positioned and engaged along a functional axis of the multi-functional valve. This combination of valves provides for a single lightweight housing for the valve. The multi-functional valve is hydraulically connected via conduits with the servo valve and the differential cylinder. This device allows for the use of a single valve arrangement for controlling the numerous operating modes of the differential cylinder or servo actuator.
