  • Patent number: 5509575
    Abstract: A flow divider for substantially eliminating fluid intensification problems and pressure surges includes a housing having an inlet, one or more outlets, and a cavity therebetween. A passageway defining spool is rotatably mounted in the housing cavity and includes passageways corresponding to the outlets that separately periodically connect the inlet to the outlets as the spool is rotated. "Floating" pistons are slideably mounted in the passageways such that the pistons reciprocate in the passageways as the spool is rotated. Specifically, the incoming hydraulic fluid pushes the pistons in the passageways away from the inlet toward the outlet causing a metered volume of pressurized fluid to be moved out of the passageways through the respective outlets and, as the spool is further rotated, the passageways become reversed such that the pistons are again positioned adjacent the inlet and are again forced away from the inlet. Thus, pressurized fluid is dispensed at a predetermined rate and proportion.
