Abstract
A wood splitter comprises a fixedly mounted splitting wedge 2 and a pressure plate 4 driven by a hydraulic ram 5,6 so as to feed pieces of wood 3 onto the wedge. Hydraulic fluid is delivered to the ram through the intermediary of a hydraulic-pressure control valve 14. Feed movement of the pressure plate is initiated only when the hydraulic pressure applied to the valve rises above a predetermined value. The pressure plate is returned to its starting position by a spring 23 when the hydraulic pressure falls below the predetermined value.
