Resonator for a pressurized fluid system

A method of reducing acoustic energy within a pressurized fluid system, comprising:

• passing an initial acoustic energy from a pressurized fluid source to a resonator fluidly coupled downstream of the pressurized fluid source, wherein the initial acoustic energy has a frequency in a range from about 1 Hz to about 500 Hz;
• attenuating greater than 70% of the initial acoustic energy having a frequency in a range from about 1 Hz to about 500 Hz within the resonator to produce a reduced acoustic energy;
• and
• passing the reduced acoustic energy from the resonator to a pressure relief device fluidly coupled downstream of the resonator, wherein the pressurized fluid system comprises:
• the resonator comprising:
• a first chamber comprising an inlet and an outlet;
• a second chamber comprising an inlet, an outlet, and a filter port, wherein the inlet of the second chamber is in fluid communication with the outlet of the first chamber;
• a third chamber comprising an inlet and an outlet, wherein the inlet of the third chamber is in fluid communication with the outlet of the second chamber;
• a fourth chamber in fluid communication with the second chamber by the filter port;
• a variable orifice unit coupled to the filter port and disposed between the second chamber and the fourth chamber, wherein the variable orifice unit has a variable passageway between and in fluid communication with the second chamber and the fourth chamber;
• the pressurized fluid source located upstream of the resonator and in fluid communication with the inlet of the first chamber;
• the pressure relief device in fluid communication with the outlet of the third chamber;
• one or more sensors detecting vibration or pressure and generating and transferring a signal indicative of the vibration or the pressure, wherein the one or more sensors are coupled to any one or more of:
• the variable orifice unit, the pressure relief device, and the outlet of the third chamber;
• and
• a controller adjusting a size or diameter of the variable passageway based on the signal received from the sensor.
