A fluid control valve

摘要

The invention provides a fluid control valve for controlling the flow of hydraulic fluid from a hydraulic pump to and from a plurality of hydraulic motors. The valvbe conveniently includes selector valve for selectively energizing a flow divider/combiner spool that controls the flow of hydraulic fluid to and from themotors. The flow divider/combiner spool has on its periphery lubrication grooves which also act as metering grooves. An advantage of the fluid control valve of the invention is that it regulates and equalises the flow and pressure of the hydraulic fluid delivered between a hydraulic pump and a plurality of hydraulic motors. thereby enabling each hydraulic motor to rotate in a synchronized fashion when traction control is required and without the operator having to deactivate the valve, the valve will disengage once traction to all wheels has been regained.
