Patent number: 7174606Abstract: A pressure cylinder including a cylinder housing having one end including an opening. A piston is axially displaceable within the cylinder housing. A piston rod is coupled to the piston and extends through the opening at the one end of the cylinder. A cylinder base closes off the cylinder at an end of the cylinder housing opposite the opening. The cylinder also includes a pressure chamber between the piston and the cylinder base and capable of being pressurized by a pressure medium and a switching disk for interacting with a switch to determine the position of the piston. The switching disk is displaceably positioned in the pressure chamber in frictional engagement and coaxially with the piston rod so that the switching disk passes to a starting position near the piston in response to a pressure impulse overcoming the frictional engagement when the pressure chamber is first pressurized.Type: GrantFiled: November 26, 2003Date of Patent: February 13, 2007Assignee: Rexroth Mecman GmbHInventors: Rudolf Möller, Dirk Kröger, Salih Agca, Christoph Leinders

Publication number: 20040165842Abstract: A flexible pressure tube includes a pressure tube cladding defining an axis and having an interior space for flow of a pressurized medium. The pressure tube cladding is constructed in the form of a homogeneous layer which is suitable to transmit data encoded in light waves in a direction of the axis, wherein the homogeneous layer is made of a flexible optical waveguide material. The pressure tube may be part of an apparatus for conducting pressurized medium and transmission of data, which apparatus includes a coupling assembly having a coupling unit for connecting one axial end of the flexible pressure tube to a pressurized-medium-operated structure, and another coupling unit for connecting the other axial end of the flexible pressure tube to a pressurized-medium-operated structure. Each of the coupling units is constructed to include a connection for the pressurized medium and an integrated communication device.Type: ApplicationFiled: February 24, 2004Publication date: August 26, 2004Applicant: REXROTH MECMAN GMBHInventors: Herbert Krebs, Wolfgang Brandes, Norbert Fortmann, Ernst-August Meyer, Thomas Liesenhoff

Patent number: 6688332Abstract: A multiway valve for controlling a flow of fluid under pressure, includes a valve housing having fluid ports and a plurality of bores in side-by-side parallel disposition substantially at a same level. Each bore is configured for accommodation of a valve spools which are sealed in the bores against the valve housing. The spools have opposite first and second end faces, and include portions of greater diameter and portions of smaller diameter. Acting on the first end face of the spools is an actuation unit for moving the spools in a longitudinal direction to thereby direct a flow of fluid under pressure between the ports, whereas a mechanical coupling mechanism, which is secured to the valve housing, interacts with the second end faces of the spools.Type: GrantFiled: January 28, 2002Date of Patent: February 10, 2004Assignee: Rexroth Mecman GmbHInventor: Thomas Liesenhoff

Patent number: 6637316Abstract: A pressure fluid cylinder with anti-rotation feature, includes a cylinder tube of non-circular inner cross section and a piston which is sealingly received in the tube. The piston has a circular cross section and is connected at one end to a piston rod in coaxial relationship. In order to allow selective use of the pressure fluid cylinder with or without anti-rotation feature, an annular adapter is placed between the piston and the tube and has a circular inner surface area to complement a circular outer surface area of the piston so as to allow a relative rotation between the piston and the adapter. The adapter has a non-circular outer surface area to complement the non-circular inner surface area of the tube. Through insertion of a fastener in aligned boreholes of the adapter and the piston, the adapter and the piston are prevented from rotating relative to one another.Type: GrantFiled: April 24, 2002Date of Patent: October 28, 2003Assignee: Rexroth Mecman GmbHInventors: Heinz-Jürgen Engelke, Norbert Fortmann, Thomas Liesenhoff, Jens Müller

Publication number: 20020147065Abstract: A tooth chain includes a plurality of links, each link having at least two spaced-apart apertures, and a plurality of pins received in the apertures for joining together the links to thereby define inner links and outer links. Each pin has a length which is sized to terminate within the aperture of the outer link, wherein the aperture has a cross sectional profile which corresponds to a cross sectional profile of a pin end at a slight clearance fit to leave a space sufficient to allow the pin end to be joined with a wall of the aperture, without projecting beyond an outer surface of the outer link.Type: ApplicationFiled: April 3, 2002Publication date: October 10, 2002Applicant: REXROTH MECMAN GMBHInventors: Klaus-Burkhard Winkelmann, Georg Twardzik
