Title:
LOW POWER CONSUMPTION BISTABLE SOLENOID VALVE
Document Type and Number:
WIPO Patent Application WO/2023/019491
Kind Code:
A1
Abstract:
A low power consumption bistable solenoid valve, comprising a valve body (2), an inlet connector (1) that is located at an inlet end of the valve body (2), and an electromagnet assembly (3) that is located at an outlet end of the valve body (2). The interior of the valve body (2) forms a bistable structure by means of the combination of a fixed cylindrical magnet (4), a ring-shaped magnet (5) and the electromagnet assembly (3). A magnetic spring is used to replace a combination of a mechanical spring and an ejector rod, and double (or multiple) coils are used to replace single coil configurations of conventional solenoid valves, thereby not only improving the reliability of a solenoid valve and reducing the energy consumption and size of the solenoid valve, but also effectively reducing the voltage required for operation of the valve. In micro electronic systems, the described bistable solenoid valve has great adaptability and application potential.
