  • CYLINDER FOR HIGH-PRESSURE HYDRAULICS
    Publication number: 20100077918
    Abstract: A cylinder for high-pressure hydraulics is disclosed, with a cylinder sleeve extending between a cylinder base and a cylinder head composed of an inner tube and an outer sleeve made from fiber-reinforced plastic placed on the inner tube. According to the invention, a weight reduction without loss of rigidity may be achieved, whereby the inner tube of the cylinder sleeve screwed to the cylinder base and joined to the outer sleeve in a thrust-resistant or shear-resistant manner engages with the cylinder head in a tensile-resistant manner.
