Document Type and Number:
WIPO Patent Application WO/2023/065754
Kind Code:
A1
Abstract:
An exhaust valve assembly, a compressor and an air conditioner. The exhaust valve assembly comprises: a flange (1) and an exhaust assembly. The flange (1) is provided with a valve seat (2), and the valve seat (2) is provided with an exhaust port (3). The exhaust assembly is provided on the valve seat (2) and comprises an upper valve piece (4) and a lower valve piece (5). The lower valve piece (5) is provided on the valve seat (2) and provided with, corresponding to the exhaust port (3), a refrigerant circulation hole (6). The projection of the exhaust port (3) along the gas flow direction completely falls within the projection range of the refrigerant circulation hole (6) along the gas flow direction. The upper valve piece (4) can seal the refrigerant circulation hole (6). One side of the lower valve piece (5) facing the valve seat (2) is provided with a damping material (10), and the damping material (10) is located on the peripheral side of the exhaust port (3). In the described exhaust valve assembly, the acting force of valve pieces hitting the valve seat can be effectively reduced, and the operation noise of the compressor is reduced.
