Electromagnetic valve
摘要:
The electromagnetic valve has a valve body capable to open and close a fluid communication path, first and second springs opposing to each other and biasing the valve body. Biasing forces of the first and second spring toward the valve body are balanced with each other so as to have valve body open the communication path. When a coil is energized, a moving member is driven so as to have the valve body move against the biasing force of the first spring during a first moving stroke so that an elastic energy may be stored in the first spring. When the coil is de-energized, the valve body is moved back by the first spring not only during the first moving stroke but also during a second moving stroke to absorb the elastic energy stored in the first spring by the second spring. There is an enough space where the moving member may move back during the second moving stroke so as not to hit any part.
