Abstract
Abstract A valve construction having a valve stem provided with a free end telescoped within an opening means in a closed end of a cupshaped member, a valve poppet being disposed in the cup-shaped member and having a valve member at the open end of the cupshaped member for seating against a valve seat. A spring means is disposed between the closed end of the cup-shaped member and the valve stem to tend to urge the free end of the valve stem into engagement with the valve poppet while permitting swivel action therebetween, the cup-shaped member having the side wall means between the closed and open ends thereof staked into recess means of the valve poppet to secure the valve construction together.
