  • Load recall valve
    Patent number: 4554947
    Abstract: A load recall valve has a mechanical memory which coordinates the releasing of the brake with the system pressure. The mechanical memory requires that the system pressure be at least equal to the system pressure just prior to when the brake was set. Setting of the brake prior to the load being taken off the system causes the memory to be activated. Setting of the brake after the load is taken off the system causes the stored memory portion to be erased.
