• an open/close device disposed in said accommodating compartment;
• and
• a dampening chamber formed in said discharge passage on a downstream side of said accommodating compartment.

A compression system having a flow of gas from an area of low pressure to an area of high pressure, said system comprising;

• a condenser;
• an expansion valve;
• an evaporator;
• a compressor;
• and
• a refrigerant circuit connecting said condenser to said expansion valve, said expansion valve to said evaporator, said evaporator to said compressor and said compressor to said condenser;
• wherein said compressor comprises a circulatory passage, said compressor circulatory passage further comprising:
• means for receiving a low pressure gas from said refrigerant circuit;

• and
• means for dampening pressure pulsations in said high pressure gas, said means for dampening being disposed on a downstream side of said controlling means.

A method of operating a compression system comprising the steps of:

• providing a gas flow circuit having a high pressure area and a low pressure area;
• receiving a low pressure gas from said low pressure area of said gas flow circuit;
• compressing said low pressure gas to form a high pressure gas;
• discharging said high pressure gas to a discharge passage in said high pressure area of said gas flow circuit;
• controlling said flow of said high pressure gas in said discharge passage between said high pressure area and said low pressure area;
• and
• dampening pulsations in said discharge of said high pressure gas in said discharge passage on a downstream side of said step of controlling.
