  • Patent number: 8770630
    Abstract: A method for providing a hose pipe connection is disclosed. Embodiments of the method start with a pipe having an enlarged end portion. A sleeve is introduced into the end of the flexible hose. The sleeve has an inner diameter that is equal to the inner diameter of the hose. In an embodiment, the inner diameter of the sleeve is increased while the end of the hose is already placed on the sleeve. The hose fitted with the sleeve is then introduced into the enlarged end of the pipe. Crimping of the enlarged end will then secure the sleeve and the hose and provide a fluid tight and mechanically sturdy connection.

  • Publication number: 20090025381
    Abstract: A servo drive includes a hydraulic cylinder. The hydraulic cylinder comprises a piston that is mounted in the cylinder and that delimits two working chambers. Relief lines connected to the working chambers via control orifices may aid the definition of the right and left end positions of the piston. The control orifices are exposed by the piston in its respective end positions, thus relieving the pressure in the active working chamber. An end stop, which may be predetermined by the position of the control orifices may be formed by the pressure relief that occurs at the relevant location in the working chamber. Such measure can relieve the pressure in the hydraulic pump, for instance in end stop positions.
