Abstract: This invention relates to a hydraulic-oil feeding device for a hydraulically operated injection timing mechanism disposed on the injection pump shaft of an injection pump for air-compressing injection-type internal-combustion engines. A pump shaft is partially disposed in an injection pump housing. A feeding member leads from the pump housing to the pump shaft. An arrangement of bores forms a passage or transition between the feeding member and the injection timing mechanism. The passage is interrupted during each injection process, and the passage is open in between injection processes.

Abstract: An arrangement of a soot filter in the exhaust gas system of an internal combustion engine equipped with an exhaust gas turbocharger whose turbine housing is arranged downstream of the exhaust gas manifold. For purposes of achieving a fastening of the soot filter at the internal combustion engine which is favorable from an assembly point of view, space-saving and compensating changes in length, the soot filter and the exhaust gas turbocharger form a unit which is retained, on the one hand, angularly movably at the exhaust gas manifold by means of a pipe connection of the soot filter and, on the other, at the crankcase by way of supports arranged at the exhaust gas turbocharger on the housing side.

Abstract: Sliding and lifting roof for vehicles having a rigid cover, which in a closed position closes a roof opening in a fixed roof surface, and therefrom, can be selectively tilted upwardly so as to raise its rear edge above the fixed roof surface, or lowered and displaced below the fixed roof surface. A frame encircling at least part of the roof opening forms a rain gutter extending below both sides of the roof opening. Strip-shaped shield elements are attached at both sides of the cover, essentially perpendicular to the cover surface, and substantially flush with its lateral edges. The shield elements are flexible, at least in the area of their lower edges, and are fixedly connected with the cover along their upper edges. In the raised position of the cover, at least a major extent of the length of the shield elements will bear laterally against the lateral edges of the roof opening.

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.

Abstract: In a two stroke cycle internal combustion engine comprising a scavenged crankcase and a fuel injection nozzle (10), the formation of a more satisfactory mixture is desired and the use of a piston having smaller dimensions is to be permitted and this is to be accomplished substantially without an increase of the technical structure expenditure. For this purpose the nozzle (10) discharges a jet of fuel from the crankcase side into the interior of the hollow piston (5) so that at least part of the discharged fuel jet impinges on the piston head (13) as the piston moves toward the crankcase (1).

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.

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.

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.

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.

Abstract: In a spoked drive wheel for a hydrodynamic torque converter operating with power splitting, having a spoke for connecting a wheel hub to an external ring of the spoked drive wheel, the spoke cross-section is designed in the shape of a wing profile extending along a profile main axis. The profile main axis is transverse to the axis of rotation of the wheel. In this way, the deterioration in the characteristics of the torque converter is kept as small as possible in both power splitting operation and in operation without power splitting.

Abstract: An independent wheel suspension for steerable wheels has a wheel bearer connected to the vehicle body and first and second guide wheel members. The first guide wheel member comprises separate guide links coupled at articulated points to the vehicle body and to the wheel bearer, and a coupler connected between the articulated points at the wheel bearer. The coupler transverses a bisector of an angle formed by the guide links and is angled rearwardly and inwardly from the wheel. This wheel suspension enables the castor distance to be increased at the wheel in a curve during wheel turning, while maintaining a specified basic arrangement for the guide links.

Abstract: A propulsion control system for motor vehicles in the range of the cornering limit speed, having a memory in which the momentary steering angle value is stored when a certain steering angle change is not followed by a change of the lateral acceleration, having threshold value comparators in which the actual steering angle is compared with threshold values that depend on the stored steering angle value, and having logic for transmitting and stop transmitting a signal to a control element for the power reduction of the vehicle engine when the actual steering angle exceeds one threshold value and then falls below the other threshold value. The steering angle may also be replaced by the driving speed or by a combination of both quantities.

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.

Abstract: A liquid friction coupling, which preferably constitutes a differential arranged in the shaft line between two driven axles of a vehicle, consists of a rotatable housing (1), which is filled with a viscous liquid, a shaft (2), which protrudes into the housing (1), and a number of interdigitating blades (5, 6). The blades (5) of one set are non-rotatably connected to the housing (1) and the blades (6) of the other set are non-rotatably connected to the shaft (2). The shaft (2) includes a cavity (4), which serves to receive liquid from the housing (1) and contains a spring-loaded slider (8). In order to effect an automatic control of the torque which can be transmitted during the starting period, the slider in the cavity (4) of the shaft constitutes a sliding valve member (8), which cooperates with slots or the like, which are formed in the shaft and lead into the housing (1). The sliding valve member (8) is adjustable in dependence on a performance variable, preferably in dependence on temperature.

Abstract: A cocking slide (2,3) for automatic hand firearms serves for manually pulling back the spring loaded lock of the weapon by means of a one-way coupling (8,9). The cocking slide (2,3) comprises a handle (3), projecting laterally from the weapon, which possesses a device (11,12,13) for arbitrarily blocking the one-way coupling (8,9). In order to safeguard the cocking slide (2,3), in spite of it being easy and safe to actuate, against damage by the effect of external forces, and to enable the lock to be urged forward by means of the cocking slide (2,3), the handle (3) consists of a guiding part (4) and a grip part (6). The grip part (6) is spring-loaded and slewable about an axle parallel with the barrel. Moreover, the grip part is slewable toward the weapon against spring bias over the entire path of the cocking slide, whereby the one-way coupling (8,9) can be blocked.
