Method and apparatus for suppressing resonance

A compressor discharging pressurized fluid to a pipe connected to the compressor, the compressor comprising:

• a pressurized zone, wherein pressurized fluid is intermittently supplied to the pressurized zone;
• an accommodation chamber located between the pressurized zone and the pipe;
• a valve body located in the accommodation chamber, the valve body being movable within the accommodation chamber between a first position, at which the accommodation chamber is connected to the pressurized zone, and a second position, at which the accommodation chamber is disconnected from the pressurized zone, wherein the pressurized fluid in the pressurized zone urges the valve body toward the first position;
• and
• a spring for urging the valve body toward the second position, wherein the valve body is supported only by the spring, the spring exerting a predetermined force on the valve body such that the frequency of pressure variation of the pressurized fluid differs significantly from the natural frequency of the pipe.
