A compressor (10), in particular a compressor for compressing a coolant, including one or more pistons (12), a cylinder block (16), and a compressor housing which at least partially houses the compressor (10), the piston(s) (12) being arranged in corresponding cylinder bores or cylinders (14) arranged at least partially in the cylinder block (16) and/or in the compressor housing so that they can move back and forth. The compressor (10) also includes an impedance tube (36) and an outlet (30) for releasing the coolant from the compressor, (10) in particular an outlet flange (32). Said compressor (10) has an associated high pressure volume (24), for one or more, in particular, for respectively two cylinders (14), and a common high pressure volume (26), in which the individual high pressure volumes (24) join, the common high pressure volume (26) being connected to the outlet (30) and the impedance tube (36) being arranged in the connection between the common high pressure volume (26) and the outlet (30) or the connection is created between the common high pressure volume (26) and the outlet (30). The invention also relates to a corresponding coolant circuit and to a corresponding air-conditioning system.
