Title: Accelerated rod and sinker bar break out device

Abstract: An accelerated rod and sinker bar break out device having a base, a pivoting hydraulic cylinder with a stationary wrench and a pivoting wrench. A hydraulic control assembly controls hydraulic cylinder operation and has a manifold with input port for receiving hydraulic fluid from a reservoir and an output port for transferring hydraulic fluid to the reservoir. The manifold can have a first bidirectional control port to flow hydraulic fluid to and from a first pivoting hydraulic cylinder port and a second bidirectional control port to flow hydraulic fluid to and from a second pivoting hydraulic cylinder port. The manifold has a lever, which movably changes hydraulic fluid flow rates to the pivoting hydraulic cylinder and interfaces with a primary pressure adjustment valve.
