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.

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.

An electronically controlled pressure regulator for regulating a pressure of a diphasic fluid contained in an accumulating chamber between a higher pressure delivered by a pressure source and a lower discharge pressure delivered by a pressure well, the regulator comprising: a first solenoid valve; a transfer volume filled with gas connected to an upper volume of gas of the diphasic fluid of the accumulating chamber by the first solenoid valve; a second solenoid valve connecting the transfer volume to the pressure source; a third solenoid valve connecting said transfer volume to the pressure well; a pressure sensor operably connected to said accumulating chamber and measuring a fluid pressure in said accumulating chamber; and an electronic control system connected to said pressure sensor and controlling said first, second and third solenoid valve dependent on the fluid pressure sensed by said pressure sensor.
