Abstract

Priority valve is one of the key components of hydraulic steering-system, and its performance decides the stability of steering-system. Taking the YXL priority valve as an example, it established the static flow mathematical model of priority valve, and analyzed the influences of the steering load p₁, EF oil-way load stress p_e, relative open area A₂ between valve spool and valve cover of steering gear, entrance flow q₀ and control pressure p_c of spring on the flow stability of hydraulic steering system. The results showed that increasing the control pressure p_c of spring can improve the flow stability of CF oil-way.
