ABSTRACT:
A pressure control valve having improved damping means which permits the valve to have a high degree of response combined with improved stability. The valve includes a valve spool mounted within a valve body and shiftable against spring pressure from a normal position to a nominal design operating position wherein discharge ports in the valve body are placed in communication with the inlet port. First damping means are provided which become operational only as the control member attains the nominal design operating position, the first damping means including an orifice in the valve body and a ring carried by the valve spool, the ring overlying the orifice when the valve spool attains its nominal design operating position. Second damping means apply unidirectional damping acting during departure of the control member from its design operating point, the second damping means including the aforesaid ring and a cylindrical wall of the valve body, the ring and the cylindrical wall defining an annular damping orifice.
