  • Patent number: 5375638
    Abstract: An improved hydraulic log splitter which includes a hydraulic reservoir formed integrally with a frame of the log splitter. Hydraulic fluid from the reservoir is supplied by a pump to a control valve. A fluid passage is open through the control valve to a hydraulic intensifier which includes a cylinder and a piston extendable from the cylinder. The piston pushes a log against a stationary splitting wedge. The piston is urged toward a retracted position by a return spring internal to the cylinder. When the control valve is in other than an "extend" position, hydraulic fluid supplied to the control valve is allowed to flow into a return conduit back to the reservoir. In this condition, the pressure the hydraulic fluid develops insufficient force to overcome the force exerted by the return spring, and the ram remains retracted.
