Abstract
An accumulator assembly for a motor vehicle powertrain includes an armature and a follower. Together the armature and the follower can selectively lock together. The accumulator assembly may include a biasing member and a solenoid. When the solenoid is de-energized, the biasing member pushes the armature towards the follower to lock the armature and the follower together. When the solenoid is energized, the armature is magnetically drawn towards the solenoid and away from the follower to unlock the two components and to compress the biasing member.
