Hydraulic Pressure Reducing Valve for Aircraft

Aircraft often use common hydraulic energy, load pressure requirements of hydraulic users are different, and different pressure levels can be set to complete the necessary functions. Different pressure levels are achieved by pressure reducing valves. This chapter introduces a kind of hydraulic pressure reducing valve with fixed orifice and pressure sensing chamber, including working principle and basic characteristics, as well as static and dynamic characteristics. This new hydraulic pressure reducing valve with fixed orifice and pressure sensing chamber includes a valve body, valve core, spring and spring seat. The new structure of the valve body and valve core form a pressure sensing ...
