Abstract
A hydraulic support element for mounting a movable part at a stationary support or carrier, comprising an elongate support ledge having a bearing surface for slidingly supporting the movable part. The support ledge together with the support or a part arranged at the support delimits a hydraulic pressure chamber containing hydraulic medium which is under pressure and by means of which the hydraulic support element is supported at the support. The support ledge is supported at the support by means of at least two hydrostatic support arrangements having substantially cylindrical guide surfaces. These hydrostatic support arrangements being arranged adjacent one another in the lengthwise direction of the support ledge and containing piston-like parts.
Claims25
A hydraulic support element for mounting a movable part upon a stationary support, comprising:
- an elongate support ledge having a bearing surface for slidingly supporting the movable part;
- said elongate support ledge together with said support or a part arranged at the support delimiting a hydraulic pressure chamber for a hydraulic medium which is under pressure and by means of which the support element is supported at the support;
- said elongate support ledge having an extended dimension sufficient for coacting with at least two hydrostatic support arrangements;
- at least two hydrostaic support arrangements having substantially cylindrical guide surfaces for supporting the elongate support ledge at the support;
- and
- said two hydrostatic support arrangements being dispositioned adjacent one another in the lengthwise direction of the elongate support ledge and containing substantially piston-like parts.
