Abstract of the Disclosure The pressure regulator includes a valve member which is supported to slide back and forth in a valve housing having a high pressure port, a low pressure port and a bypass port. Pressure fluid from the high pressure port is bypassed through the valve member via an orifice, a passage and a metering opening formed in the valve member, the passage communicating with a compensating chamber located between the valve member and the valve housing. As the bypass flow increases, the increased pressure drop across the orifice reduces the pressure in the chamber to compensate for the progressive resistance imposed upon the valve member by a bias spring and by increasing fluid reaction forces. The compensating chamber enables the regulator to maintain a more substantially constant pressure drop across the high and low pressure ports of the regulator at various bypass flow rates.
