A chassis and/or supporting structure of a motor vehicle, in particular of a passenger vehicle, is entirely or partially designed as a hollow chamber sheet structure.
摘要:
In an injection system with pressure intensification with a simple and space-saving design, control means are provided permitting a large range fuel injection pressure control, which also permits rapid adaptation of the fuel injection pressure to the various engine operating conditions.
摘要:
A motor vehicle has an outer contour around which the headwind flows when driving has associated with it flow-influencing structure to reduce the air resistance of the motor vehicle is known. The flow-influencing structure are movably mounted in a vicinity of the outer contour and can be activated periodically with the aid of drive devices in order to introduce suitably time-dependent disturbances into the flow of the headwind in the vicinity of the flow-influencing structure.

A control valve for the fuel return in an injection line in internal combustion engines, which has a valve tappet which is arranged in a longitudinally displaceable manner and which exposes larger valve cross sections as the opening stroke increases and can be actuated against the restoring force of a valve spring by an electric magnet coil. The opening stroke and hence the valve cross section can be adjusted by a spring assembly having at least two actuating springs which can be deflected in the axial direction of the valve tappet and are arranged in parallel and in such a way that they can be subjected to force in an axially offset manner with the result that different resultant spring forces counteract the actuating movement in successive sections of the spring travel. To allow accurate setting of the valve position, especially in the intermediate positions, the invention makes provision for the actuating travel of the valve tappet to be limited by an axially displaceable stop which is in operative connection with a second actuating drive, independent of the magnet coil, and, in a direction opposed to the actuating drive with the spring assembly.
摘要:
A method and device for measuring screw threads on tubes connecting sleeves or the like, by means of a measuring pin which is moved to measured surfaces in two mutually independent measuring directions offset by 90.degree. from each other. The two measuring directions are associated with a force direction effective as a resultant. The measuring pin further has an advance deflection in each of the two measuring directions which are annulled at the point contact of the measuring pin with the measured surfaces.

A radial shaft sealing ring comprises a stiffening ring as well as a sealing lip and an annular seal which are integrally combined by radial connecting sections running through notches in the stiffening ring. The annular seal is mounted in recesses in the stiffening ring, which have an increasing depth radially toward the driving surface.
摘要:
A hydraulic valve control arrangement is provided with a control line of a control cylinder, the control line being connected to a first oil volume, with a first control piston having a first control face and operatively connected to the first oil volume, and with a plunger piston which is arranged between the first control piston and an outlet valve and has a second control face and which is operatively connected to a second oil volume. A first control edge is provided between the control cylinder and the first control piston. The control edge switches a first throughflow connection between the first oil volume and the second oil volume operatively connected to a third control face of the first control piston.
摘要:
In a fuel injection valve for a pump-line-injector system of an internal combustion engine, comprising a fuel injector with a nozzle body, a nozzle needle longitudinally movably supported in the nozzle body between a seated nozzle closing position and a lift-off position assumed during fuel injection, the nozzle includes a fuel supply passage, a fuel drain passage, a connecting passage extending from the fuel supply passage to the fuel drain passage, and a spring-loaded pressure relief piston forming a control valve disposed in the path of the pressurized fuel from the fuel supply passage to the drain passage for controlling the pressure of the fuel supplied to the nozzle needle during fuel injection into a cylinder of the internal combustion engine.
