<p>A differential pressure regulator (10) connected in a fluid system including a bypass line (20), a high pressure inlet (32), a compensation inlet (70) connected to the high pressure side of the system, a low pressure inlet (35) and a bypass outlet (25). A spring biased reciprocable valve member (40) having an intermediate passage (60) between the compensation inlet (70) and the bypass outlet (25), a metering port (50) between the intermediate passage and the bypass outlet (25), and a compensating port (45) between the compensating inlet (70) and the intermediate passage (60). The high and low pressure inlets (32, 35) are coupled to high and low pressure faces (41, 42) on the valve member. A compensating chamber (80) including an inlet (85) connected to the intermediate passage (60) and a third pressure face (90) results in a compensating force which moves the valve member (40) toward the closed position.</p> |
