Proportional priority flow regulator with reverse flow control

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 first row of cross-sectional holes adjacent to the outlet port, a second row of cross sectional rows adjacent to the regulated port, and an internal void, the internal void communicating with the first and second rows of 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 second row of cross-sectional holes, and a reverse flow path is defined from the regulated port to the outlet port through the internal void and through the first row of cross-sectional holes;
• a compensating spool slidably arranged within the cage, wherein a change in a pressure differential across the compensating spool moves the compensating spool to increase or decrease the opening of at least one of the rows of cross-sectional holes to control the flow of fluid along at least one of the flow paths;
• a regulating spool slidably arranged within the cage, wherein the regulating spool has a cross hole and an internal chamber, the internal chamber communicating with the regulating spool cross hole and the internal void of the cage;
• and
• an electro-magnetic actuator disposed on the valve assembly opposite the housing, wherein when a current is applied to the electro-magnetic actuator, a magnetic force moves the regulating spool to at least partially align the cross hole with the second row of cross-sectional holes to increase the scope of communication between the second row of cross-sectional holes and the regulated port.

• means for providing a reverse flow path from the regulated port to the outlet port through the internal void;
• and
• a compensating spool slidably arranged within the cage, 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.
