A discharge system for compressors of the type which comprises: a cylinder block defining a compression chamber ( 2 ); a first discharge chamber ( 4 ); a second discharge chamber ( 6 ) in direct communication with the first discharge chamber ( 4 ); a third discharge chamber ( 7 ) in constant fluid communication with the second discharge chamber ( 6 ) and opened to a discharge tube ( 5 ), said discharge system comprising a valve means ( 22 ) which assumes an open position, communicating the first and the third discharge chambers ( 4,7 ) when a gas mass flow passing from the compression chamber ( 2 ) to the first discharge chamber ( 4 ) reaches a determined gas mass flow value, and a closed position blocking, at least in most part, said fluid communication between the first and third discharge chambers ( 4,7 ) when said gas mass flow reaches values that are lower than the determined gas mass flow value.
