Abstract (en)
[origin: EP2048456A1] In a refrigerant circuit (10) of a refrigerating apparatus (1), a pulsation absorbing device (30) is provided. In the pulsation absorbing device (30), a piston (32) is accommodated in a cylinder member (31) to divide its cylinder chamber into a pressure buffering chamber (33) and a back pressure chamber (34). The pressure buffering chamber (33) is connected to a second high-pressure refrigerant pipe (12) on the inflow side of an expander (22) through a first connection pipe (35). The back pressure chamber (34) is connected to a first high-pressure refrigerant pipe (11) on the discharge side of a compressor (20) through a second connection pipe (36) and a capillary tube (37).
