Abstract: A hydraulic tilting mechanism for a driver's cab of a vehicle, with the mechanism including a double-acting working cylinder having accommodated therein a displaceable piston. Ducts or lines are provided for connecting the working cylinder with a supply tank or source of hydraulic fluid, with a pump being arranged in one of the ducts or lines and a joint control valve for controlling a movement of the piston being arranged in the ducts or lines. A closable duct by-passes the working cylinder and branches off from a three-way valve having two switch positions. The three-way valve is located in the duct or line leading to a first cylinder space which causes a tilting of the driver's cab. The three-way valve is adapted to be electromagnetically switched by way of a key. The closable duct or by-pass line discharges into a connecting duct or line arranged between the control valve and a second cylinder space which is adapted to cause a return of the driver's cab.

Abstract: A hydraulic braking system for two-wheeled vehicles, with the system including a main brake cylinder associated with a rear axle braking circuit and a main brake cylinder associated with a front axle braking circuit, as well as with a braking force distribution device. The braking force distribution device is adapted to produce, in a specified ratio, a pressurization of both the rear axle braking circuit and front axle braking circuit when the main brake cylinder associated with the rear axle braking circuit is actuated. When the main brake cylinder associated with the front axle braking circuit is simultaneously manually actuated and the main brake cylinder of the rear braking circuit is actuated by a brake pedal, the force distribution device produces a reduction of the rear axle braking pressure.

Abstract: A two-door passenger motor vehicle is provided with a mechanism for feeding a locking clasp and/or belt strap of a seat belt system, with the mechanism including an overload safety device for stopping a motor of the feeding mechanism so as to protect it and a power source, such as a vehicle battery, from damages when an obstacle is projected into the course of movement of the feeder arm, or the feeder arm is in an end position and is no longer reversed or switched off. The overload safety device also responds in the case of a delay-dependent blocking of the belt strap, but initiates a new feeding movement. When the front end position is reached, an automatic return of the feeder arm by a predetermined amount takes place so as to release a blocking effect of a belt roller of the seat belt system and the feeder arm is then subsequently returned to a retracted position.

Abstract: A multicylinder internal combustion engine, especially a self-igniting internal combustion engine, with supply ducts leading to the cylinders which supply ducts emanate from a common fuel supply chamber with the ducts being supplied with a fuel-gas mixture. The fuel-gas mixture is present in a mist form in the supply chamber with the fuel, with a substantially identical droplet size, exhibiting a droplet diameter at which a flow characteristic is obtained for the droplets in the ducts leading to the cylinders which is respectively at least approximately identical to the flow characteristic of the gas. The fuel is fed to the common supply chamber continuously by way of an injection device with the premixed fuel-gas mixture, which is at a pressure elevated with respect to the pressure level in the supply chamber, exiting from the injection device at a speed of sound with atomization of its proportion of fuel, on account of a pressure jump at a cross section of the discharge orifice of the injection device.

An ignition starter switch is connected to the control device in such a manner that the timing valve is fully open during an operation of the ignition starter switch so as to enable a starting boost. An adjustable timing member is coupled to an operating switch provided in the control device, which operating switch closes automatically after a termination of the starting process. The timing member maintains the timing valve in a fully open position during a specific time span so as to provide for an after-start boost.
