A switching drum seal () for a switching drum () for sealing an intake pipe in an intake manifold system of a multi-cylinder internal combustion engine, having two spaced-apart, circumferentially extending circumferential sealing sections () with circumferential sealing surfaces () and two spaced-apart, axially extending axial sealing sections () with axial sealing surfaces () and having at least one resilient element () to impart resilience to at least one circumferential sealing section () perpendicular to its circumferential sealing surface. The resilient element () extends in a region between the switching drum () and one of the circumferential sections () and is supported on the switching drum ().

Switching drum seal

A valve, particularly a switching cylinder, for opening and closing a pipe, especially for use in an intake manifold for a multi-cylinder internal combustion engine having an air distribution chamber and individual intake pipes positioned next to one another which terminate in a flange, in which the valve is positioned in an individual intake pipe to close or open the respective intake pipe, and the valve has at least one sealing system mounted in a radially movable manner such that, in the closed position, it presses against the pipe inner wall to form a seal, and in the open position and in the pivot range from the closed position to the open position, it forms a gap between the valve and the pipe inner wall.

Valve for opening and closing a tube

An intake pipe ( ) for an internal combustion engine composed of shells ( ) in which the geometry of the joining surfaces ( ) adopts an approximately stepped course in areas with a slight incline relative to to joining force (F). This produces areas with a greater or lesser inclination relative to a joint line ( ) indicating the average inclination of the joining surfaces. This results in areas which can be welded with a high degree of stability because of their considerable incline towards the joining force. These areas can then support areas which are less inclined towards the joining force. This allows the shells ( ) to have strongly curved joining surfaces, which increases the geometric design freedom of the intake pipe and, in particular, makes it possible to manufacture intake pipes with strongly curved intake channels constructed from just two shells.

An intermediate flange system for an internal combustion engine with direct fuel injection. The intermediate flange system is mounted between the intake device and the cylinder head and includes two subunits ( ). The first subunit includes a basic body ( ) and is responsible for conducting the fuel. The other subunit includes a basic body ( ) and serves to conduct the intake air. Both basic bodies can be optimally designed as a function of demands to which they are subjected. Thus, basic body ( ) is preferably made of synthetic resin material, and basic body ( ) of aluminum. Consequently, the overall intermediate flange system is lighter than prior art systems, which heretofore have been made entirely of aluminum.

A duct system suitable for use as an intake manifold for an internal combustion engine, including flap valves ( ) for selective opening and closing of the ducts. The positions of the valves are continuously adjustable in order to produce a swirl in the flow of combustion air. To achieve this, a high degree of angular precision is required in the positioning of the valves. Intake manifold manufacturing tolerances need to be compensated during assembly of the valves. A valve adjusting mechanism is provided in mechanical couplings ( ) of the valve linkage between the position adjusting motor ( ) and the flap valves ( ).

Port system, especially an induction manifold for an internal combustion engine

A duct system, especially an intake manifold for an internal combustion engine, having flap valves ( ) for selective opening and closing of at least some of the ducts. The valves should be continuously adjustable in position in order to produce a swirl in the combustion airflow. To achieve this a high degree of angular precision is required in the positioning of the valves. Intake manifold manufacturing tolerances need to be compensated during assembly of the valves. Valve adjusting mechanisms are provided on the axles of the valves or in the mechanical connections of the valve gear pertaining to the valve drive mechanism.

An intake device for an internal combustion engine, comprising welded shells joined along a partition line, in which the partition line is provided with a region for producing inclined additional surfaces, which generate a transverse force Q due to their inclination relative to a pressure force D applied for welding the shells. This transverse force Q offsets a transverse force Q which is generated as a result of the inclination of partial regions of the partition line relative to the applied pressure force D. In this way, the transverse forces which arise during production of the intake device may be at least partially offset in the component, so that little or no forces are exerted on the molding tools, and the welding results for the intake pipe may thus be improved.

A multi-component hollow structure including at least two synthetic resin housing parts ( ) with corresponding sealing surfaces ( ), and at least one half wall per housing part, in which the half walls of one housing part meet corresponding half walls of the other housing part in order to reinforce the hollow structure, and in which the corresponding sealing surfaces ( ) and the half walls ( ) are joined using a friction force, such as vibration welding or ultrasonic welding. A method for producing such multi-component hollow structures is also disclosed.

Plastic hollow structure

An apparatus for moving a valve flap, especially in the air intake duct of an internal combustion engine, including a vacuum box ( ) which executes a longitudinal movement in dependence on the application of a negative pressure or vacuum, and the longitudinal movement of the vacuum box is transmitted via a coupling rod ( ) to a traverse rod ( ), which in turn is connected to an actuating lever ( ) for the valve flap ( ). The coupling rod ( ) and traverse rod ( ) system allows the vacuum box to be arranged in any position relative to the valve flap ( ). The apparatus can be simplified further by combining the diaphragm disk ( ) with the coupling rod ( ) to form a single, integral part. In this case, a force is exerted eccentrically on the vacuum box. The eccentrically exerted force can be compensated by the diaphragm having a shape other than a round contour.

Device for moving a valve flap

A filter element for an air filter, including a filter insert (,) and a seal (,) extending around the outer edges of the filter insert on the flat side thereof; the filter insert being folded in a zig-zag or pleated form and being composed of filter paper or filter fabric. The filter element (,) rests against parts of a filter housing through the seal (,). The folded filter insert has a contour on one side which deviates extensively from a plane, at least in certain predetermined areas, thus creating a continuous zig-zag fold.
