The piston pump is the key power component in the civil aircraft hydraulic system, and the most common pump used in the aviation field is the pressure compensated variable displacement type. In this review paper, a basic introduction to the civil aircraft piston pump is presented,including the ...
In this method, the pressure which is applied at a particular point is used for generating extremely large forces. So this principle is used by several hydraulic systems. The major components of the hydraulic actuator mainly include a spool valve or pilot valve & main cylinder or power cylinder...
