Abstract
A ride control valve includes a valve housing () having a main spool () longitudinally displaceably arranged in the valve housing, a balance spool (), and fluid passage points for a pressure supply (P), a tank return line (T), an accumulator () and a boom cylinder unit (). The balance spool () continuously balances the pressure between the fluid ports of the accumulator () and the boom cylinder unit (). The main spool () is controlled by the operator and initially interconnects these fluid ports of the accumulator () and the boom cylinder unit (), starting from a closed fluid connection, via a restricted fluid connection, to a fully opened fluid connection, or disconnects them from each other in reverse sequence.
