Double-acting working cylinder connection - uses distribution plate with integral channels for fluid medium

摘要

The unit connects the working cylinder to its associated control valve. It has first and second pressure medium channels between a first and second working cylinder connection aperture and a first and second control valve aperture. Both pressure medium channels are at least partly formed in a distribution unit and open into a plate surface. The valve surface having the working apertures is directly placed onto the plate. The channels also open into plate passage bores which are aligned with the connection apertures of the working cylinder. The bores contain fitted hollow bolts with a radial connection aperture. They are screwed into the cylinder apertures to tension the unit onto the cylinder and externally seal the bores.
