  • Hydraulic fluid containers and reservoirs
    Patent number: 4840206
    Abstract: A hydraulic fluid container (10,110) is specially adapted to mate with a vehicle hydraulic fluid reservoir (40,160) for the purpose of transferring fluid from the container to the reservoir. In one embodiment a spout (24) has a particular cross section which matches the opening (46) in the reservoir. In another embodiment a valve (148,150,216, 218,316,318,416,418) in the container or reservoir is opened by a probe (164,232,332) in the other of the container and reservoir when the container and reservoir are mated together. The invention prevents fluid from a container not specially adapted to the reservoir being added to reservoir.
