Abstract
A check valve includes a modulation and/or anti-oscillation feature which, in one aspect, modulates the position of the check valve ball relative to the valve seat to maintain the ball in a continuous flow position allowing pressurized fluid flow past the ball while preventing contact between the ball and the valve seat. In another aspect, an increased mass is selectively coupled to or forms a part of the movable valve member to dampen oscillations of the movable valve member in an open fluid flow position without contact with the valve seat.
