Poppet valve with dual flow area gain
Abstract:
A poppet valve includes a housing having an inlet port and an outlet port. A poppet is located in the housing and includes a poppet body which blocks the outlet port when the valve is in a closed position and a poppet tip disposed at a distal end of the poppet body. The poppet tip includes at least one tip flow channel extending substantially along a poppet axis to meter flow therethrough as the valve is moved from a closed position. A method of controlling a flow includes translating a poppet located in a valve housing in a first direction along a poppet axis. At least one poppet flow channel extends across a valve inlet port via translation of the poppet. A fluid is flowed from the inlet port through a first flow area defined by the at least one poppet flow channel extending across the inlet port.
