Log splitter hydraulic cylinder reset spring device

摘要

A reset spring device for a one-log splitter single-action hydraulic cylinder comprises a spring guide, reset spring, bearing, curved transmission lever, and guide seal. The spring guide has a first end and second end, the reset spring housed within the spring guide, the bearing housed within a portion at the first end, the spring abutting the bearing, the guide seal disposed at the first end of the guide, the transmission lever positioned outside the spring guide and engaged with the bearing. The transmission lever having a curved protrusion operably engaged through a longitudinal opening on the spring guide and through a groove on the bearing. A push plate is connected to the lever. During operation, when a cylinder is pushing forward, the lever compresses the spring through the bearing; and when a handle is released, the log splitter ceases operating, the cylinder is reset by each reset spring device.
