  • Test for hydraulic leakage
    Patent number: 6668620
    Abstract: A test for hydraulic leakage in hydraulic components uses a rate testing device having two circuits including a filling circuit that fast-fills the component with hydraulic fluid and a leakage circuit that measures the leakage rate of fluid flow through the component. The filling circuit is first connected to the component to fill the component. Once full, flow through the filling circuit is blocked and flow to the component is provided by the leakage circuit, which includes a leakage flow rate measuring device. The filling circuit provides a flow rate that is at least twice the flow rate that is provided by the leakage circuit.
