Abstract:
A proportional priority flow regulator comprising:a housing having a longitudinal cavity, an inlet port, an outlet port, and a regulated port;a cage disposed within the longitudinal cavity, the cage having a row of cross-sectional holes and an internal void, the internal void communicating with the cross-sectional holes, the inlet port, and the regulated port, wherein when the regulator is in an open position, a primary flow path is defined from the inlet port to the regulated port through the internal void and through the row of cross-sectional holes; anda compensating spool having a hollow portion and slidably arranged within the cage, the compensating spool permitting the flow of fluid along a reverse flow path defined from the regulated port, through the internal void, through the hollow portion of the compensating spool and to the outlet port, wherein a change in a pressure differential across the compensating spool moves the compensating spool to increase or decrease the opening of the row of cross-sectional holes to control the flow of fluid along at least one of the flow paths.
