Abstract: A lubricating-oil filter with a filter pot arranged on a filter base, which is provided with an assembly opening adapted to be closed by a cover and in which a filter cartridge is adapted to be inserted by way of the assembly opening; a bolt retained at its upper end at the cover and at its lower end in the filter base is provided with an intermediate channel that connects a filtered-oil chamber of the filter pot with a base channel, itself connected with a filter base connection for the outflow of the filtered-oil; the fastening means for the cover are thereby structurally separate from the bolt and are arranged outside of the bolt axis while the mounting support for the upper end of the bolt is located at the bottom side of the cover and the mounting support for the lower end of the bolt is constructed as slide seat.

Abstract: A two-circuit brake system for motor vehicles with a shiftable master brake cylinder which includes two pressure spaces for the two brake circuits, of which the pressure space for the front axle brake circuit has a larger cross section than the pressure space for the rear axle brake circuit and which are connected with each other by a line extending externally of the master brake cylinder, whereby a shifting valve operating in dependence on the vehicle load is arranged in this line which is able to establish and interrupt the connection between the two pressure spaces; an intermediate piston is arranged between the two pressure spaces in the master brake cylinder coaxial to the two pressure pistons, which is freely movable within a guide sleeve of smaller diameter and is provided with central extensions on both sides thereof for the mechanical cooperation with the two pressure pistons; the shifting valve is thereby adapted to be shifted as a function of the load, of the pressure prevailing in the brake cylind

Abstract: A chassis frame for motor vehicles in which cross members projecting from sides of the frame interconnect longitudinal members in the form of hollow girders. The longitudinal members have openings in their side walls, and these openings conform with the cross-section of the cross members. The cross members have a center section and abutting end sections inserted from the sides through the openings into the hollow interior of the longitudinal girders. The cross members pass through the longitudinal members so that the end sections project beyond these longitudinal members. The center section of the cross members penetrate the wall of the longitudinal members facing the vehicle center. The center section and the end sections abutt each other bluntly and are connected to each other by welds within the interior of the hollow section of the longitudinal members. The end sections of the cross members, furthermore, pass through the outer wall of the longitudinal members.

Abstract: Injection device for injecting fuel into a combustion space such as an auxiliary combustion space of an external auto-ignition internal combustion engine of the type operating on the stratified-charge principle. The injection device includes a housing accommodating a movable pump plunger, a movable nozzle needle controlling the nozzle orifice opening into the auxiliary combustion space, and a movable piston-type storer. The pump plunger is configured to close off respective fuel return and fuel supply lines during its pumping stroke, at which time it effects a build up of pressure resulting in movement of the piston type storer until a predetermined sufficient pressure is reached to force the nozzle needle away from the closed position to thereby effect injection of fuel into the auxiliary combustion space.
