ABSTRACT:
A substantially constant flow regulating valve includes a piston dividing a bore into two chambers. The piston is spring biased toward the top chamber of the bore. Fluid from the inlet enters the top chamber through a reference pressure passage and exerts a downward force on the piston. Fluid from the inlet also passes through an inlet flow throttle and into the bottom chamber of the bore where it exerts an upward force on the piston in concert with the spring force. The piston includes an end which variably interacts with an orifice in the lower chamber to maintain a constant pressure differential between the top and bottom chambers.
