Document Type and Number:
WIPO Patent Application WO/2022/161429
Kind Code:
A1
Abstract:
An electrically-operated valve, which comprises a valve seat component (10) and a valve core rotor assembly (20); the valve core rotor assembly (20) comprises a valve shaft assembly (201), a valve core component (202), first and second elastic members (208, 204), and an abutment component (206); the valve shaft assembly (201) comprises a valve shaft abutment portion (20154); the valve core component (202) comprises a first valve core abutment portion (202b), and the first valve core abutment portion (202b) is able to abut against the valve shaft abutment portion (20154); the first elastic member (208) is in abutment with the valve shaft assembly (201), the abutment component (206) comprises a first abutment portion (206a), and the first elastic member (208) is in abutment with the first abutment portion (206a); the abutment component (206) comprises a second abutment portion (206b), the valve core component (202) comprises a second valve core abutment portion (202c), and the second abutment portion (206b) is able to abut against the second valve core abutment portion (202c); the abutment component (206) comprises a third abutment portion (206c), and the third abutment portion (206c) is able to abut against the valve shaft assembly (201); the second elastic member (204) is in abutment with the valve shaft assembly (201), the abutment component (206) comprises an abutment component hole portion (206d), and the valve core component (202) or the second elastic member (204) passes through the abutment component hole portion (206d); the valve core component (202) comprises a third valve core abutment portion (202d), and the second elastic member (204) is in abutment with the third valve core abutment portion (202d). Impact force of a valve core (2023) on a valve port (10a) at the moment the valve core (2023) makes contact with the valve port (10a) can be reduced.
