The separator (,) has a tubular inlet opening (,) and two tubular outlet openings (,) which are connected with one another in a flow-carrying manner. A separating device (,) is disposed in the flow direction (,) between the inlet opening (,) and the outlet openings (,). One of the outlet openings (,) carries substantially only separated liquid and the other outlet opening (,) carries substantially only gas freed of liquid. An outer tube (,) surrounds an inner tube (,) with an all-around space between them. The inner tube (,) is connected at one end to the inlet opening (,) in a flow-carrying manner, and at the other end is associated with the outlet opening (,) for the separated liquid.

An elastic bearing includes a support and a thrust bearing. Each is provided with a fastening element and each are braced against each other by at least one elastic spring element of an elastomeric material and at least one damping device. The support includes a supporting body made of a tough material, which extends essentially transverse to the direction of the introduced vibrations. The thrust bearing includes a drum-shaped housing which essentially encloses the supporting body on all sides. The supporting body is adjoined by at least one ring-shaped damping element made of an elastomeric material which, under static preloading of the bearing, abuts on the front-side inner surfaces of the housing in a substantially stress-free manner. In the cylindrical recess of the damping element at least one elastic spring element is arranged axially on both sides of the supporting body. The elastic spring elements, under axial prestressing, are braced between the surface of the supporting body and the respective adjacent front-side inner surface of the housing.

A regulating valve, comprising a housing having a cylindrical valve chamber, is disclosed. The valve chamber is provided with at least one inflow and at least two outflow ports. The inflow and the outflow ports can be at least partly closed off as required by a single common valve body arranged in the valve chamber that can rotate about an axis. The valve body acts as a rotary valve and can be actuated by a drive. The inflow and/or at least one of the outflow ports is surrounded on the side of the housing facing the valve body by a seal. The seal can be brought into sealing engagement with the valve body under an elastic preload. The valve body has an extension in the peripheral direction of the valve chamber that is delimited in each case by an edge, such that the flowoff edge passing over the inflow port while it is opening has an axially extending elliptical indentation.

An active positioning element for a rubber mount, including a space surrounded by a housing, a positioning member and a working member which is designed as a spring element arranged within the space. The positioning member and the working member are movable back and forth in the direction of oscillations introduced into the rubber mount, and the positioning member is sealed in the housing. The positioning member is formed by a gas pressure spring which can be acted on by gas under pressure, the gas pressure spring comprising at least one piston-cylinder unit which has a roller membrane for sealing the piston off from the housing. The spring element is formed by a compression spring which, in the direction of the oscillations introduced, rests under elastic initial stress, on one side against the positioning member and on another side against the support bearing of the rubber mount.

A device for controlling engine exhaust emission for use on an internal-combustion installation, in which a soot filter is arranged in an exhaust-gas system. The soot filter is made up of a flexible filter band that is traversed by the flow of exhaust gas in a first zone and which can be moved forward and renewed, continuously or intermittently, by a drive mechanism. The filter band is supported at least in the first zone by a flexible, moveable, endless conveyer belt that is permeable to gas and that absorbs tensile stresses. The filter band and the particles separated out of the exhaust gas by the filter band are burned together in a second zone.

A resilient coupling for use between two, relatively-movable machine parts has a resilient body and an integral projection jutting out from the profile of the resilient body. A surface of the resilient body is arranged for joining, for example, adhesively, to one machine part and a surface of the projection arranged for joining, for example adhesively, to the other machine part, the jut of the projection and its surface for joining to the machine part preferably being perpendicular to each other.

Rubber coupling

A process of producing a resilient coupling in a clearance space between two, relatively-movable elements with a polymeric material introduces the polymeric material contactingly into a clearance space between the elements. A portion of the polymeric material is softened at least while in contact with the clearance-space surface for adhesion when solidified thereafter into a resilient body for the coupling, but a portion of the clearance-space surface is arranged to prevent adhesion. The combination provides coupling with guidance of the relative motion.
