Abstract
A check valve assembly includes a valve frame, a valve poppet, a first torsion spring, and a second torsion spring. The valve frame has an opening. The valve poppet is positionable in the opening. The valve poppet is moveable in a first direction to close the check valve assembly and moveable in a second direction to open the check valve assembly. The first torsion spring biases the valve poppet in the first direction. The second torsion spring biases the valve poppet in the first direction before the valve poppet has traveled a threshold distance. The second torsion spring biases the valve poppet in the second direction after the valve poppet has traveled the threshold distance.
