  • Patent number: 6571683
    Abstract: A double-action hydraulic cylinder (3) is provided with an axially slidable piston between a front cover and a rear cover, whereby the piston may be coupled to an extreme load through a piston rod (4) and whereby the piston may be biased via connections (5) for a hydraulic medium at both sides with the hydraulic medium from an extreme pressure source. The connections (5) are attached to the cylinder barrel (6) by means of soldered joints to achieve a good surface finish and thereby also an optically appealing appearance together with a reliable mounting of the pressure connections.

  • Patent number: 6422127
    Abstract: A hydraulic actuation arrangement including a double-action working cylinder whose working chambers are in communication via a mutually unseatable check valve with one side of a reversible pressure medium source, respectively, whereby each working chamber is connected to a pressure medium reservoir by a pressure-relief valve or pressurizing valve, and at least one working chamber is furthermore connected to the pressure medium reservoir via an additional pressurizing valve. When an additional pressurizing valve is provided with two different pressure threshold values, the manual force used in emergency operation is therefore clearly reduced after introduction of the manual movement whereby these force levels for both movement directions may be selected independently from the maximum system pressure.

  • Patent number: 6227612
    Abstract: The invention relates to an operational arrangement for movable parts on vehicles, especially for hatches, movable roofs and the like. The invention provides for the automatic opening of the hatch or roof by a drive unit. The invention is characterized by placement of a drive mechanism within the vehicle, obviating the need for special coating of the drive mechanism, with transfer of forces from the interior to the exterior of the vehicle through a four joint hinge including a pivot pin which passes through the body of the vehicle and is operatively connected to the drive mechanism and the movable part.

  • Patent number: 6168393
    Abstract: A motor-driven radial piston pump assembly has its radial piston pump supported by a base section on one side thereof which likewise supports an electric motor for powering the pump which is supported on that same side coaxially. The electric motor and a hydraulic tank are directly connected to the base section, the motor being surrounded by a cylindrical-shaped motor housing forming an inner wall of the tank and being sealingly connected to the base section, the motor housing being closed by a cover on its outer end opposite the pump. Such arrangement is compact in that the electric motor is simply positioned directly on the base section and is almost completely surrounded by the hydraulic tank such that the separate motor housing of the electric motor can be of simple and light weight construction.

  • Patent number: 6067021
    Abstract: An apparatus for hydraulically operating a rear cover, covering top or the like (1) on a vehicle, with at least one double-acting hydraulic working cylinder (3), which, on the one hand, is connected to the vehicle and, on the other hand, to the covering top, includes working chambers (8, 9) in connection with each one side of a switched pressure source (12) via one check valve (10, 11) each, wherein both of the check valves have an mutually releasing device and each of the working chambers parallel with respect to the check valves is kept via a pre-stress valve (15, 16), which steers into the tank, at a specified pressure level. To realize, in a simple and safe way, a passive wedging protection, in at least one connection line (4, 5) to the working cylinder (3), a line (22) enters the tank (17), in which a proportional pressure valve (23) is inserted which is controlled by the control electronics and is equal to the exact pressure that is necessary for the movement of the covering top (1) or the like.

  • Patent number: 5760695
    Abstract: An apparatus for hydraulic actuation of a hinged cover on a vehicle having a working cylinder such that work spaces within the cylinder are respectively connected, via check valves, to a reversible pressure source. The check valves respectively contain a reciprocal unclosing facility, and the work spaces are connected, via a pilot valve, in parallel to the check valves. Between the one of the work space and one of the check valves, an emergency valve guiding off to the tank is interposed and is shut off during normal operation of the apparatus to allow a safe emergency actuation of the hinged cover.

  • Patent number: 5409076
    Abstract: A power steering system is actuated by a controller which includes a Bowden cable having a core and a sheath. The core is connected directly mechanically to a control mechanism and the sheath is connected hydraulically to the control mechanism by a control valve and an operating cylinder. To balance a reaction of the control mechanism on the core and thus undesired steering movements of the power steering system, a brake unit is disposed between the core and the sheath of the Bowden cable to prevent relative movement between the two by means of friction.

  • Patent number: 5404961
    Abstract: A power steering system (3) includes a controller (1) and a control mechanism (3), which can be operated by way of a Bowden cable (5) having a core (7) and a sheath (6). The core (7) is connected directly mechanically to the control mechanism (3), and the sheath (6) is connected hydraulically to the control mechanism (3) by way of a control valve (8) and an operating cylinder (9). To prevent oscillations in the closed control circuit of the power steering system, the sheath (6), or the control piston (15) of the control valve (8) connected thereto, is provided with a damping device (18) to dampen the axial movement of the control piston (15). The damping device provides hydraulic damping of the control piston (15).

  • Patent number: 5375507
    Abstract: To connect the cylinder pipe (1) of a hydraulic cylinder to a bottom (6), and a cover (8), the bottom (6) and cover (8) have groove-shaped recesses (16, 17), into which are pressed the ends (5, 7) of the cylinder pipe (1) under permanent deformation. To enable pressurization at high operating pressures, the region (25) of the inner end of the non-deformed cylinder pipe (1) is defined as a holding region (18, 19) and has a turned groove (26) which, in the deformed state of the cylinder pipe (1), reaches over the related inner edge (27) of the groove-shaped recesses (16, 17) with respect to the longitudinal stretch of the cylinder pipe (1).
