Three-way valves and fuel injectors using the same |
摘要 |
Three-way valves having reduced leakage and fuel injectors using the same. Three-way spool poppet valves are disclosed having a spool with a poppet valve thereon cooperating with a seat on the valve housing to provide a substantially leak free valve closing in one direction characteristic of a poppet valve while preserving the advantages of a spool valve. Three-way ball valves are also disclosed having substantially leak free valves closing in both directions, but further including reduced short circuit losses due to direct flow from a high pressure source to a low pressure vent during transition of the ball from one position to the opposite position. Fuel injectors with direct needle control using the three-way valves of the present invention are also disclosed. |
