Pressure differential regulator

A pressure differential regulator for controlling pressure differentials within a supply source that supplies a first fluid and a second fluid at differing pressures through first and second discharge ports, comprising:

• a. a first sensing chamber in fluid communication with the first discharge port for receiving the first fluid;
• b. a second sensing chamber in fluid communication with the second discharge port for receiving the second fluid;
• c. a multi-layered diaphragm for separating the first and second sensing chambers;
• d. a first outflow restriction valve means affixed adjacent a first outer layer of the diaphragm within the first sensing chamber for restricting outflow of fluids through a first fluid outlet out of the first sensing chamber in response to contraction of an internal volume of the first sensing chamber by the diaphragm;
• e. a second outflow restriction valve means affixed adjacent an opposed second outer layer of the diaphragm within the second sensing chamber for restricting outflow of fluids through a second fluid outlet out of the second sensing chamber in response to contraction of an internal volume of the second sensing chamber by the diaphragm;
• f. a first leakage measuring means, in fluid communication with a first leakage cavity defined within the multi-layered diaphragm, for measuring flow of leaked first fluid passing through the first outer layer of the diaphragm into the first leakage cavity and on out of the regulator through a first leakage evacuation means;
• and
• g. a second leakage measuring means, in fluid communication with a second leakage cavity defined within the multi-layered diaphragm, for measuring flow of leaked second fluid passing through the second outer layer of the diaphragm into the second leakage cavity and on out of the regulator through a second leakage evacuation means.

A pressure differential regulator for controlling pressure differentials within an electrolytic cell that supplies a first fluid and a second fluid at differing pressures through first and second discharge ports, comprising:

• a. a first sensing chamber in fluid communication with the first discharge port for receiving the first fluid;
• b. a second sensing chamber in fluid communication with the second discharge port for receiving the second fluid;
• c. a multi-layered diaphragm for separating the first and second sensing chambers, wherein the multi-layered diaphragm defines a first leakage cavity between a first outer layer and a central layer, and defines a separate second leakage cavity between a second outer layer and the central layer, so that any first fluid leaked through the first outer layer passes through the first leakage cavity out of the regulator, and any second fluid leaked through the second outer layer passes through the second leakage cavity out of the regulator;
• d. a first contracted sensing chamber outflow restriction valve affixed adjacent the first outer layer of the multi-layered diaphragm that restricts outflow of the first fluid through a first fluid outlet out of the first sensing chamber in response to contraction of an internal volume of the first sensing chamber by the multi-layered diaphragm;
• and
• e. a second contracted sensing chamber outflow restriction valve affixed adjacent the second outer layer of the multi-layered diaphragm that restricts outflow of the second fluid through a second fluid outlet out of the second sensing chamber in response to contraction of an internal volume of the first sensing chamber by the multi-layered diaphragm,
• so that, whenever the multi-layered diaphragm expands into and contracts the internal volume of the first sensing chamber, the first contracted sensing chamber outflow restriction valve restricts flow out of the first fluid outlet while the second contracted sensing chamber outflow restriction valve simultaneously enhances flow out of the second fluid outlet, and whenever the multi-layered diaphragm expands into and contracts the internal volume of the second sensing chamber, the second contracted sensing chamber outflow restriction valve restricts flow out of the second fluid outlet while the first contracted sensing chamber outflow restriction valve simultaneously enhances flow out of the first fluid outlet.
