发明名称 HYDRAULIC UNIT
摘要 A hydraulic unit comprises a hydraulic cylinder with a piston (02), a hydraulic pump (15) with a driving motor (12) and a hydraulic accumulator of the piston or diaphragm type, and which hydraulic unit besides is adapted so that a hydraulic fluid in the accumulator and the cylinder always is subject to pressure above atmospheric irrespective of the piston position, the fluid communications in the hydraulic unit are all formed inside the structural elements of the hydraulic unit, such as inside covers, piston rod, cylinder tubes or similar elements, the hydraulic unit is characteristic in that one of the structural elements is a distributing element (04) with fluid communication ducts for flow of hydraulic fluid between the hydraulic pump (15), the hydraulic accumulator (07) and the hydraulic cylinder, and having respective side faces to which the pump (15), the accumulator (07) and the cylinder, respectively, is removably secured, so that among others the distributing element forms the bottom cover for the hydraulic cylinder. Thereby is obtained that the parts being removably secured to the distributing element can be replaced by parts with different performances.
