Document Type and Number:
WIPO Patent Application WO/2024/001523
Kind Code:
A1
Abstract:
Provided are an exhaust valve assembly and a scroll compressor comprising same. The exhaust valve assembly comprises: an exhaust valve casing (1), comprising a side wall (11) and a hollow chamber (12), wherein the side wall (11) is provided with at least one first exhaust passage (111), a first end (13) of the exhaust valve casing (1) is provided with a gas release passage (15) and partially closes the hollow chamber (12), and a second end (14) can be connected to a compressor static disk; a piston (2), arranged in the hollow chamber (12) of the exhaust valve casing (1), the shape of the piston (2) being matched with that of the inner wall of the exhaust valve casing (1); an extension and retraction structure (3), arranged in the hollow chamber (12) of the exhaust valve casing (1), two ends of the extension and retraction structure (3) being respectively connected to the first end (13) of the hollow chamber (12) and the piston (2), and extension and retraction of the extension and retraction structure (3) driving the piston (2) to move in an axial direction of the exhaust valve casing (1). The hollow chamber (12) of the exhaust valve casing (1) serves as an exhaust chamber, and the first exhaust passages (111) of the side wall (11) of the exhaust valve casing (1) serve as silencing exhaust holes, thus reducing exhaust noise and exhaust pulsation, and improving the use experience of a user.
