ABSTRACT:
In a valve, the valve poppet member is constructed from a spring material where a tubular wall portion has a spiral wall configuration intermediate of a supporting base and a valve head. The spiral wall configuration has inner and outer diameters, a specific number of revolutions with a spiral width and a width of material remaining to provide sufficient cantilever strength to support the valve head and has the desired spring rate to seat the valve head on a valve seat.
