  • Lubrication system
    Patent number: 4869463
    Abstract: A lubrication system for leading a lubricant from a lubrication unit to a point to be lubricated, the lubrication unit and said point being movable with respect to each other. The system comprises means for leading a quantity of the lubricant at predetermined intervals from the lubrication unit to the point to be lubricated. For reducing the demand for space, a fast coupler is provided for leading lubricant from the lubrication unit to the point to be lubricated. The fast coupler is arranged to be in a position allowing the flow when the lubrication unit and the point to be lubricated are interconnected and in a position preventing the flow when the lubrication unit and the point to be lubricated are detached from each other.
