| The oil-filled chamber, shown in yellow, is de-pressurized
by the piston's downward motion. This causes the diaphragm to
deflect downward, drawing gas into the cavity, shown in blue.
The process is reversed when the piston move upwards, pressurizing the oil, deflecting the diaphragm upward and forcing the gas out of the cavity. Close window to return to the Burton Corblin website |
