1. A normally-on control valve comprising:
- a housing having a top surface, a bottom surfaces and a longitudinal axis extending between the top surface and the bottom surface, the housing further including;
(1) a delivery port;
(2) a supply port;
(3) a sink port;
a valve body formed within the housing, the valve body comprising;
(1) a first ring defining a first annular fluid flow path disposed within and coaxial with the longitudinal axis of the housing, the ring having an entry;
(2) a second ring defining a second annular fluid flow path opposedly disposed the first ring and coaxial with the longitudinal axis of the housing, the second ring having an entry;
(3) a valve disk disposed intermediate the first ring and the second ring, the valve disk movable between a position abutting the first and the second rings, andwherein when the disk abuts the second ring it thereby connects the supply port with the delivery port and blocks the sink port, and when the disk abuts the first ring it thereby connects the delivery port with the sink port and blocks the supply port.
