ABSTRACT:
A coupling for use in supplying air pressure to an air driven pump on a pallet is disclosed. The male half of the coupling is affixed to a pallet changing station and the female half is suspended from a pallet. Suspension of the female half from the pallet enables the male and the female half to couple despite misalignment. The male half includes two pistons and the female half includes a power port, a vent port and a central port. The power port is connected to an air driven hydraulic pump and the control port is connected to a pilot on a four-way valve. The hydraulic pump operates vides contained on the pallets. The number of vices operable is only limited by the capacity of the hydraulic reservoir located in the pallet.
