Abstract
A multi-way valve includes a control pressure channel, first and second control fluid channels, a valve body in the first and second control fluid channels, and an electrically controlled device having a drive member and an armature. The armature moves back and forth by the drive member between inactive and active positions. Movement of the armature from the inactive to the active position displaces the valve body arrangement to an active position, closing the first and opening the second control fluid channel is open. The electrically controlled device includes a drive body connected to the armature and a first spring member between the armature and the drive body. The valve body arrangement is biased towards the inactive position by a second spring member. The armature in the inactive position is biased towards the active position by a third spring member. Also disclosed is an actuator including the valve.
