ABSTRACT:
Apparatus for improving the efficiency of filtering fluid of a hydraulic system, including a venturi adapted for connection to a first fluid carrying conduit of the hydraulic system for receiving a flow of the fluid therefrom, the venturi having a restricted passage extending therethrough and an orifice communicating therewith, a diverter conduit connected in communication with the orifice and with a second fluid carrying conduit of the hydraulic system, the diverter conduit containing a restricted orifice therein, and the venturi having an outlet connected in fluid communication with a filter, wherein the flow of the fluid through the restricted passage of the venturi will generate a reduced pressure condition in the diverter conduit to divert at least some of the fluid in the second fluid carrying conduit of the hydraulic system into the diverter conduit so as to pass into the venturi and flow onto the filter, the reduced pressure condition being weak or strong in correspondence to the fluid flow through the venturi so as to regulate the diverted flow.
