ABSTRACT:
A compression spring is formed of elastic material in a shape resembling a trumpet horn. Novel valve structures incorporate the trumpet horn spring as a component, the latter of which serves therein to make the valve self restoring and also to provide a fluid seal. One valve is principally applied to dispense pressurized fluid and the other is a simple gravity fed beverage tap.
