ABSTRACT:
An elongated tubular housing, having inlet and outlet ports, forms a fluid passageway. A piston, loosely received by the inlet end portion of the housing, is coaxially connected with a throttle regulator comprising poppet type valves and a stem which extends through and seats the valves on respective end portions of a cage positioned in the outlet end portion of the housing. A spring, interposed between the piston and the cage, normally biases the valves toward an open position and acts to position the balanced valves at the respective end portions of the cage in response to constant fluid pressure drop across the piston.
