Abstract
An apparatus including a body, a mandrel disposed at least partially within the body, and a spring. The spring maintains the mandrel in a retracted position within the body until a predetermined pump rate is applied. The spring allows the mandrel to move to an extended position when the predetermined pump rate is applied. The spring returns the mandrel to the retracted position within the body when the predetermined pump rate is removed.
