Document Type and Number:
WIPO Patent Application WO/2022/247872
Kind Code:
A1
Abstract:
A solenoid valve assembly and a control valve assembly comprising same. The solenoid valve assembly comprises: a fixing frame (41) and a coil (42), the coil (42) being wound on the fixing frame (41), and the fixing frame (41) being internally provided with a second circulation channel extending along the height direction of the fixing frame (41) and passing through the fixing frame; a fixed core (30), the fixed core (30) being mounted in the second circulation channel, at least a portion of the fixed core (30) extending upward from the second circulation channel, and the fixed core (30) being provided with a flow channel (30a) extending along the height direction of the fixed core (30) and passing through the fixed core; a casing (46) mounted in the second circulation channel, the casing (46) having one end connected to the fixed core (30) and the other end extending downward from the second circulation channel, and a valve port being provided at the other end of the casing (46); and a movable core (43) movably provided in the casing (46), the movable core (43) having a first initial state that the valve port is blocked and a first open state that the valve port is open. By means of the solenoid valve assembly, the technical problem in the prior art that solenoid valve assemblies are too large in size can be solved.
