Abstract (en)

[origin: WO2009079727A1] The attenuation system is applied to a compressor which comprises: a cylinder (2) having an end closed by a valve plate (4) provided with a discharge orifice (4a) and defining, with the cylinder (2), a compression chamber (6), a cylinder cover (5) being seated against the valve plate (4) and defining a discharge chamber (7), which communicates with the exterior of the compressor through a discharge tube (8). The attenuation system comprises: at least one intermediary chamber (10) defined in the interior of the discharge chamber (7), in order to receive, from the discharge orifice (4a), the whole discharge flow coming from the compression chamber (6); and at least one connecting tube (20) mounted in the interior of the discharge chamber (7), having a first end (21) open to the interior of the intermediary chamber (10) and a second end (22) open to the interior of the discharge chamber (7).
