Document Type and Number:
WIPO Patent Application WO/2022/199252
Kind Code:
A1
Abstract:
An electromagnetic valve (100) and an electromagnetic valve assembly (200). The electromagnetic valve (100) comprises a valve body (1), a blocking assembly (2), and a first elastic member (3); the end of a first mounting cavity (11) close to a valve opening (12) is provided with a position-limiting portion (13) integrally formed with the valve body (1); the first elastic member (3) is sleeved on the blocking assembly (2); the first elastic member (3) has one end abutting against the blocking assembly (2), and the other end abutting against the valve body (1); and the outer side surface of the end of the first elastic member (3) abutting against the valve body (1) abuts against the position-limiting portion (13). The position-limiting portion (13) and the valve body (1) are integrally formed, such that the assembly efficiency of the electromagnetic valve (100) and the position-limiting effect on the first elastic member (3) are improved.
