ABSTRACT:
A portable hydraulic injection unit having a housing containing a liquid reservoir and a plurality of vertical cylinders. A manifold is in fluid communication with the reservoir and individual inlet hoses connect the manifold with each cylinder. A check valve is located between the manifold and each cylinder to prevent back flow from the cylinders into the manifold. A piston is located within each cylinder and a piston rod is attached to each piston and extends upwardly out of the cylinder and is connected to an operating arm for raising and lowering the piston rods and pistons relative to the cylinders. An outlet is located at the lower end of each cylinder and an outlet hose is connected to the outlet to transmit liquid from each cylinder to an injector at the end of each outlet hose. A check valve is located between each cylinder and its outlet hose. A wheeled dolly supports the hydraulic injection unit.
