Patent number: 11905974Abstract: Disclosed is a suction damping case. A refrigerant introduced into the suction damping case flows for a predetermined period of time at reduced pressure and speed, and then is discharged to the outside of the body, so that a damping function can be made. When the suction damping case is coupled to a rear housing, a hook and an embossing prevents the suction damping case from being separated.Type: GrantFiled: May 29, 2019Date of Patent: February 20, 2024Assignee: Hanon SystemsInventors: Kyu Namkoong, Seong Gyu Gong, Eun Gi Son, Bok Ki Park, Hew Nam Ahn
