Patent number: 6695113Abstract: A valve arrangement arranged in a flow connection between a storage chamber and an operating chamber is actuated by means of an electromagnetic actuating device and, depending on an input rotational movement to a closure element, controls a fluid flow from the storage chamber into the operating chamber. Rotational movement is provided by a rotary armature arranged immediately next to an electromagnet and fixed to a common shaft with the closure element. The magnetic flux path of the electromagnetic actuating device is shortened and thus the efficiency of the arrangement is increased significantly.Type: GrantFiled: May 13, 2002Date of Patent: February 24, 2004Assignee: Horton Sachs GmbH & Co., KGInventor: Manfred Lutz

Patent number: 6530462Abstract: A fluid clutch includes a first transmission element and a second transmission element which is rotatable about an axis of rotation with respect to the first transmission element. Torque transmission surfaces of the first and the second transmission elements are located opposite one another in a working fluid region in which torque transmission coupling can be made selectively between the first and the second transmission elements by means of fluid. A valve arrangement can be actuated for selectively making and breaking a fluid flow connection between a fluid storage region and the working fluid region, in order respectively to allow and prevent the ingress of fluid from the fluid storage region into the working fluid region and a braking apparatus can generate a braking force acting on the second transmission element. Two components are movable with respect to one another within a limited range of movement by the transmission of braking force to the second transmission element.Type: GrantFiled: March 9, 2001Date of Patent: March 11, 2003Assignee: Mannesmann Sachs AGInventor: Manfred Lutz

Patent number: 5346441Abstract: According to an illustrative example of the present invention, an internal combustion engine is provided with a gear box. This gear box is driven by an end portion of the crank shaft. A belt pulley is provided around the axis of the gearbox. The belt pulley drives through a belt an electric power generator. The gear box contains a planetary gear of variable transmission ratio. The change of transmission ratio is effected by an hydraulically operated clutch. The hydraulically operated clutch is actuated by a hydraulic actuating device. The hydraulic actuating device is actuated by oil pressure. The oil pressure is obtained by a hydraulic pump integrated into the gear box. Further components of the circuitry containing the pump and the hydraulic actuating device are provided outside the gear box. These external components are carried by a carrier plate. This carrier plate contains side by side channels of the hydraulic circuitry.Type: GrantFiled: February 3, 1993Date of Patent: September 13, 1994Assignee: Fichtel & Sachs AGInventors: Walter Kurz, Reinhard Deppert, Wolfgang Baier, Manfred Lutz

Patent number: 5318486Abstract: The drive hub for a vehicle, particularly for a bicycle, includes a hub axle 1, a hub shell 9 rotatable relative thereto, and a driver or actuator 13 mounted on the hub axle 1. The driver 13 drives the hub shell 9 over a ball friction gear 17, the ball carrier plates 25 and 27 of which form with the hub axle 1 a rigid gear housing the balls 35 of which, with a guide ring 33, a drive ring 51 and a driven ring 55, enter into a frictional connection which, by the swivelling of the axle pins 37 between drive ring 51 and driven ring 55, permits different rotational speeds. The pressure forces are produced by a thread 47 between driver 13 and drive sleeve 49 proportionally to the driving torque, the pressure spring 57 ensuring a dead-travel-free response of the ball friction gear 17.Type: GrantFiled: August 14, 1992Date of Patent: June 7, 1994Assignee: Fichtel & Sachs AGInventor: Manfred Lutz

Patent number: 4885922Abstract: The locking drive for a central locking system of a motor vehicle comprises a support which carries an electric motor, the direction of rotation of which is reversible. Guided for movement on the support are two force-transmitting parts of a gear mechanism which transmits the locking forces, a first force-locking part being adapted to be driven by the electric motor while a second force-locking part can be driven manually, for example by means of a mechanical lock. The second force-transmitting part can be locked at least in one of its extreme positions and relative to the support by means of a locking member. The locking member is controlled via the first force-transmitting part which, for this purpose, is coupled via a dead travel coupling having given clearance to the second force-transmitting part.Type: GrantFiled: February 4, 1988Date of Patent: December 12, 1989Assignee: Fichtel & Sachs AGInventor: Manfred Lutz

Layered electrophotographic recording material containing selenium, arsenic and bismuth or tellurium
Patent number: 4877700Abstract: An electrophotographic recording material comprises a dual photoconductive layer applied to an electrically conductive substrate. The lower layer disposed on the substrate is made of an amorphous system of selenium and arsenic containing 18 to 37 percent by weight arsenic. The layer thereabove is made of As.sub.2-x Bi.sub.x Se.sub.3 or As.sub.2 Se.sub.3-y Te.sub.y. The recording material is highly sensitive in the visible spectral range as well as in the IR range and can therefore also be used for recordings with solid state laser diode radiation. In cyclic operation, the material exhibits only slight fatigue.Type: GrantFiled: June 28, 1988Date of Patent: October 31, 1989Assignee: Licentia Patent-Verwaltungs-GmbHInventors: Manfred Lutz, Bernd Reimer -

Patent number: 4519227Abstract: The central locking installation for motor vehicle door locks blocks the locking element of the door lock by means of an additional, separately controllable blocking member. The locking element and the blocking member are driven by separate electrical drives which are connected into mutually parallel-connected current paths of one common drive current circuit. The drive direction of the two drives is controlled by common switches of a pole-changing circuit which reverses the current direction. Into the current path of the drives of the blocking member there is connected a control switch by way of which these drives can be switched on selectively. In the unlocking direction and the unblocking or releasing direction a time control system controllable by means of the door key in the unlocking of the door switches on the drives of the locking element and of the blocking member simultaneously. In the locking of the door lock only the drive of the locking element is switched on in its locking direction.Type: GrantFiled: March 23, 1983Date of Patent: May 28, 1985Assignee: Fichtel & Sachs AGInventors: Gerhard Dumbser, Manfred Lutz, Rainer Fey, Kurt Weiss

Patent number: 4494782Abstract: The drive device for a locking mechanism of a motor vehicle door lock which can be fastened by means of a central locking installation comprises an operating element which is guided on a housing for linear displacement between a fastening position and an unfastening position and is coupled with the fastening mechanism. A motor drives the operating element in both directions of displacement. A locking lever mounted on the housing for pivoting about a spindle extending transversely of the direction of displacement of the operating element in its locking position blocks the operating element when it is situated in the fastening position. Thus the fastening mechanism in the locked condition cannot be unfastened manually. The locking lever is pivoted by a rotating drive through an eccentric. The eccentric engages in an aperture of the locking lever. The aperture permits a pivoting movement of the eccentric of more than 180.degree., while a stop face of the aperture limits the range of rotation of the eccentric.Type: GrantFiled: March 24, 1983Date of Patent: January 22, 1985Assignee: Fichtel & Sachs AGInventor: Manfred Lutz
