  • Patent number: 4706459
    Abstract: In a hydraulic dual-circuit brake system for motor vehicles, especially high-powered heavy passenger cars, in which the front wheel brakes combined in a front-axle brake circuit are exposed to higher thermal loads than the rearward brakes, brake fluid is conveyed by means of a feed pump to the outlet-pressure space for cooling the front wheel brakes following a braking phase. Circulated brake fluid flows from the master cylinder outlet pressure space assigned to the front-axle circuit, to the wheel brake cylinders, to an additional functional space of the primary piston in the master cylinder, and back to the supply vessel. The circulating fluid pump is controlled by a timing relay which is tripped by the brake-light switch and remains energized for a predetermined time interval to allow sufficient cooling by fluid circulation.

  • Patent number: 4706738
    Abstract: The application relates to a radiator grill for motor vehicles which comprises a plurality of lamellae oriented parallel and arranged at mutual intervals, the free interstices between the lamellae being able to be closed by pressurizable flexible hose(s) as a function of the cooling water temperature of an internal combustion engine, with each of the pressurized adjacent hose(s) being braced mutually in the closed position. The invention provides that such a radiator grill can be developed so that no particularly high pressure needs to be exerted to deform the hose(s), since the hose(s) flex into a closing position and no particularly high strength requirements need be imposed for the resilient properties of the hose material as the hose(s) flex outwardly and do not inflate. Additionally, a simple clip mechanism is provided to attach the hose(s) to the lamellae.

  • Patent number: 4706627
    Abstract: A speed governor for injection pumps in internal combustion engines with a regulating sleeve which at maximum rotational speed of the internal combustion engine is displaced as a function of speed within the regulating sleeve travel against the force of the main regulating spring that acts on a force transmitting lever. The regulating movements of the force-transmitting lever are transmitted onto the fuel delivery adjusting member of the injection pump by means of at least one intermediate lever. The internal combustion engine rotational speed can be influenced by means of an operating element adapted to be controlled. In case of a needed change of the beginning of the full-load speed regulation of the internal combustion engine, the spring travel of the main regulating spring is influenced by means of a force-transmitting element.

  • Patent number: 4704863
    Abstract: An exhaust gas filter for Diesel engines that consists of a monolithic filter block made of a porous ceramic material having a plurality of ducts extending in the flow direction of the exhaust gases, said ducts alternately being closed by plugs in order to force the passage of gas through the duct walls into adjacent ducts. In the case of this exhaust gas filter, the filter block is divided into zones having a decreasing porosity in the flow direction of the gases, and the plugs which force the passage of the gas through the duct walls are each arranged in the area of the zone border. Filters are preferred that have two to four zones of decreasing porosity. The exhaust gas filters are manufactured in that a filter blank that has the largest desired porosity is immersed in a solution or suspension of a porosity-reducing agent up to the desired zone border and is subsequently dried and is possibly burnt. Preferred agents for reducing the porosity are water glass solutions or cordierite suspensions.

  • Patent number: 4705354
    Abstract: A method wherein two light fluxes I.sub.1 and I.sub.2, spectrally encoded by interspersing or alternating line frequency spectra, are transmitted through an optical fiber from a transducer to an evaluation unit which generates an indication signal in relation to the ratio of the optical power of the two light fluxes. Both light fluxes I.sub.1 and I.sub.2 are generated with distinctly different narrow-bandline structures of the spectral distribution of their optical powers with the spectral separation of adjacent lines of the two line fluxes being greater than the linewidth of these lines. The optical power of the spectrally interposed light fluxes I.sub.1 and I.sub.2 are measured individually after spectral separation by filters which are selected to the specific distribution of the light fluxes I.sub.1 and I.sub.2.

  • Patent number: 4703947
    Abstract: This invention relates to an arrangement of a torsion bar stabilizer at a drivable motor vehicle axle with independent wheel suspensions, the wheels of which being guided by means of a plurality of individual links.By means of this arrangement, a housing of the torsion bar stabilizer between the axle and the vehicle body is made to require little space in upward direction. The assignment of the stabilizer legs to the wheel carriers also do not force a limitation of the rim of tire width of the vehicle wheels. According to the invention, this is achieved by the fact that the legs of a U-shaped torsion bar stabilizer are in each case arranged between a camber strut and the axle shaft of the wheel suspensions. Thus the stabilizer legs are located inside the wheel suspensions or behind their wheel carriers and no longer project over the same in an upward direction.

  • Patent number: 4702492
    Abstract: A seat belt system is disclosed having a triggering element that is set to a certain deceleration value and the signal of which, via a lock switch that is opened when the latch of the seat belt is engaged and via a pull switch closing at a certain pulling force that is applied to the seat belt by the user, triggers one indicating element respectively, such as a fuse, according to the position of the switches. The lock switch and the pull switch as well as the indicating elements are inaccessibly arranged in the belt buckle. From the combination of triggered or untriggered indicating elements, it can be concluded whether the seat belt was put on functionally correctly or had not been put on and whether manipulations took place at the belt buckle by means of electrical signals or mechanical forces.

  • Patent number: 4702333
    Abstract: A steering apparatus for a motor vehicle has a steering gear connected to a first set of vehicle wheels, and a selectable auxiliary steering gear connected to a second set of wheels. The steering gear for the first wheel set is connected to a steering wheel and includes a hydraulic servo mechanism which provides steering assistance to the steering gear when the force required to turn the steering wheel exceeds a predetermined limit. A hydraulic pressure transmitting device is attached to the gear output of the steering gear and is hydraulically connected to the auxiliary steering gear. The pressure transmitting device transmits hydraulic pressure to the auxiliary steering gear, when auxiliary steering is selected, which varies in correspondence with movements of the gear output of the steering gear and which is independent of the pressure supplied to the hydraulic servo mechanism.
