Abstract
A sprung gate for a valve having an endless elastic band sandwiched between a first gate member that defines a first opening therethrough, which includes a flange oriented parallel to and extending in a direction opposite to a flow direction through the sprung gate, and a second gate member that defines a second opening therethrough, which has an elongate throat extending therefrom toward the first gate member. The endless elastic band spaces the first gate member a distance apart from the second gate member and the terminus of the elongate throat is seated within the flange of the first gate member to define a continuous passage through the sprung gate.
