Abstract
An electromagnetic valve includes a valve body, a valve core, and an electromagnetic drive device. The valve body has an operation chamber, wherein the valve core is movably arranged in the operation chamber. The electromagnetic drive device is arranged in the valve core and is suitable for being electrically connected with a power source. The electromagnetic drive device is arranged, when driving the electromagnetic valve, to provide the valve core with a starting drive so as to drive the valve core to enter a running state. After the valve core is driven to enter the running to state, to provide the valve core with a maintaining drive so as to keep the valve core in the running state.
