MATERIALS HANDLING VEHICLE HAVING A MANIFOLD LOCATED ON A POWER UNIT FOR MAINTAINING FLUID PRESSURE AT AN OUTPUT PORT AT A COMMANDED PRESSURE CORRESPONDING TO AN AUXILIARY DEVICE OPERATING PRESSURE

摘要

A materials handling vehicle is provided comprising: a power unit; a work assembly coupled to the power unit comprising a first auxiliary device; and a fluid supply system. The fluid supply system may comprise: pump structure for supplying a fluid; a first manifold apparatus located on the power unit; a second manifold apparatus located on the work assembly; and fluid supply line structure coupled between the first and second manifolds. The first manifold may receive fluid from the pump structure and comprise valve structure for maintaining fluid pressure at an output port of the first manifold apparatus at a commanded pressure substantially equal to or greater than an operating pressure of the first auxiliary device.
