International Classification:

F16K 31/10
F16K 31/06
F16K 31/363

Abstract:

A valve includes a solenoid with a chamber housing a pin that actuates when the solenoid is energized. The valve also includes a spool housed within a sleeve. The sleeve includes a supply section with a supply port in communication with a supply source and a tank section with a tank port in communication with a reservoir. The spool includes a body including a first passage receiving fluid from the supply source when an opening for the first passage aligns with the supply port. When the solenoid is energized and the opening for the first passage aligns with the supply port, fluid from the supply source (i) applies a force to the spool body in a direction of actuation by the pin and (ii) flows to a second passage within the valve.

Abstract:

A hydraulic system for controlling a pair of steerable caster wheels includes a left steering command valve, a right steering command valve, and a rear steering control valve. A supply pressure fluid circuit interconnects a pressure source and the rear steering control valve. A command valve supply fluid circuit interconnects the rear steering control valve with both the right steering command valve and the left steering command valve. A left side steering fluid circuit interconnects a left side actuator and the left steering command valve. A right side steering fluid circuit interconnects a right side actuator and the right steering command valve. A fluidic tie rod fluid circuit interconnects both the left side actuator and the right side actuator with the rear steering control valve. A tank return fluid circuit interconnects the rear steering control valve, the left and right steering command valves, and a tank.
