flowing in the conduit means 13 and branch lines 13b to supply fluid by way of conduit 25 to the accumulator 26 until pressure builds up within the system again to a level sufficient to shift the spool 34 back to its open position and simultaneously operate switch 19 cut off the motor 11 the accumulator 26 is preferably of sufficient volume to provide a significant number of cycles of the hydraulic cylinder 30 for correcting steering in the vehicle with this arrangement the fluid from the accumulator will be sufficient to activate the steering system for a considerable number of cycles and thus prevent constant starting and stopping of motor 11 and the resultant wear and tear thereon because of the relatively high pressures and flow rates required for the lift cylinders of a lift truck the fluid pressure and flow rate to the steering valve 15 may be excessive for optimum operation the system may then be modified by flow control and pressure reducing valves within the system as seen in fig1 this valve 45 will simply be placed within the system in line 13c between the juncture of the branch conduit 13b and conduit 25 the valve 45 may be of any suitable type but as best illustrated in fig4 comprises a housing 46 having first and second cylindrical bores 47 and 48 connected by a passage 49 a pair of metering spools 50 and 51 are respectively mounted within the bores 47 and 48 and are biased toward their open position by spring assemblies 52 and 53 the spools 50 and 51 include respective metering slots 54 and 55 for communicating fluid between central bores thereof 56 and 57 the.
