REFRIGERANT ACCUMULATOR, IN PARTICULAR FOR MOTOR VEHICLE REFRIGERANT CIRCUITS

摘要

The present invention relates to a refrigerant accumulator (1). The refrigerant accumulator (1) comprises: an accumulation container (2); and a suction tube device (3) arranged inside the accumulation container. The suction tube device (3) is composed of an outer suction tube (4) and an inner suction tube (5). The suction tubes are arranged coaxially with a gap therebetween, and are connected to each other via a method of forming a flowing path (8) using a connection part (6) on a lower end of the suction tubes (4, 5). Oil orifice holes (7) are arranged radially in the connection part (6). The oil orifice holes connect the oil sump region (9) of the accumulation container (2) to the flowing path (8) in the suction tube device (3).
