Abstract
A valve assembly positionable between open and closed positions in response to pressure differentials only comprising a valve chamber having an inlet and an outlet defined by a circumferentially extending tapered wall defining a valve seat adjacent the inlet and an outlet wall with at least one port adjacent this outlet. The assembly further comprises a valve element having a truncated frusto conical body portion and an outer peripheral tapered surface complementing the taper of the valve seat and a pad of smaller diameter than the largest diameter of the body portion depending from a large end of the body portion engageable with the outlet wall and displaced from the outlet port to permit flow from the inlet through the outlet when the valve is in the open position.
