Valving system for water flow to turbine engine emission system

Image Number 3 for United States Patent #5131426.

An improved valve for controlling flow of water to a turbine engine is disclosed. A hydraulically actuated spool valve controls the volume of water flow. An inventive seal and drain system ensures that no hydraulic oil mixes with the water being directed to the turbine engine, which would increase emissions from the engine. Further, the system ensures that no water will intermix with the hydraulic fluid in the pressure chambers for the spool valve, which could degrade the oil in the hydraulic system.
