  • Apparatus for detecting operational anomalies in pressurized fluid circuits
    Patent number: 5595138
    Abstract: The present invention relates to an apparatus for detecting operational anomalies in a pressurized fluid circuit having a main pump, a fluid filter and a booster pump connected in series. The apparatus has an indicating detector to provide an indication of a system malfunction and a switching device connected to the indicating detector, as well as to various points in the pressurized fluid circuit, to enable the indicating detector to detect a malfunction in either the booster pump or the filter. The switching device has pressurized fluid inlets connected to a point upstream of the booster pump, a point between the booster pump and the filter inlet and to a point between the filter outlet and the inlet of the main, high pressure pump.
