COUNTERBALANCED REFUELING ARM ASSEMBLY

摘要

. A rigid conduit refueling system for aircraft consisting of a wheeled support platform upon which swivel joints connected to a fuel supply source communicate with an arm conduit having a lower end pivotally mounted to the support platform and the upper end communicates with three elbow swivel couplings associated with a nozzle whereby the nozzle may be attached to the aircraft fuel tank inlet. Counterbalancing expansible chamber motors associated with the support platform and arm conduit bear the weight of the elevated components as controlled by a closed fluid circuit.
