ABSTRACT:
An accumulating chamber has its fluid pressure regulated between the pressure of a given source pressure value and a discharge pressure value. Electronic control of the accumulating chamber pressure is accomplished by a regulator having a transfer volume and first, second, and third solenoid valves. The transfer volume is connected to the accumulating chamber by the first solenoid valve. The second solenoid valve connects the transfer volume to a pressure source at the given source pressure value. A third solenoid valve connects the transfer volume to open air. A pressure sensor measures the pressure in the accumulating chamber and is connected to an electronic control system.
