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 two-chamber engine mount has a working space and a compensation space which are filled with liquid and connected by a choke aperture having the shape of a canal. The inlet and outlet openings of the choke canal are rigidly related to the choke canal and define its beginning and end. At a distance from the inlet opening of the choke canal, at least one transverse passage opening is provided parallel to the outlet opening. The transverse passage can be shut off by a valve which can be actuated by a signal.

A resilient connecting device between an internal combustion engine and an intake pipe thereof comprises an annular cushion of resilient material and two mounting elements that are coaxial with it and fastened to the components being connected. The cushion is axially demarcated at each face by supporting surfaces that extend essentially perpendicular to its axis. The mounting elements overlap and contact the supporting surfaces. A cup spring, made of a material that does not creep, is aligned with the ring.

An apparatus for resiliently mounting a vibrating body, has a mounting bracket and a pedestal interconnected through a resilient element to define a liquid-filled hollow space. A compensating baffle bounds at least 10% of the liquid-filled hollow space and is moved by a positioning element to compensate for pressure variations in the liquid caused by vibrations, of the body. The positioning element is actuated by a primary element which detects the vibrations of the body, through a freely programmable control unit.

The separator (1) has a tubular inlet opening (2) and two tubular outlet openings (3, 4) which are connected with one another in a flow-carrying manner. A separating device (6) is disposed in the flow direction (5) between the inlet opening (2) and the outlet openings (3, 4). One of the outlet openings (3) carries substantially only separated liquid and the other outlet opening (4) carries substantially only gas freed of liquid. An outer tube (7) surrounds an inner tube (8) with an all-around space between them. The inner tube (8) is connected at one end to the inlet opening (2) in a flow-carrying manner, and at the other end is associated with the outlet opening (3) for the separated liquid.

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 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.

A heating module for an internal combustion engine with external mixture formation and fuel injection and at least one intake port and one injection nozzle is disclosed. An electrically heatable heating element, which can be surrounded by flow on all sides, is arranged in the intake port, the heating element being capable of connection to an electrical power supply by means of terminals. The heating element is formed by a laminated composite part which has a trough-shaped cross section transverse to the direction of flow.

A flexible bearing for supporting a body, in particular, for supporting an internal-combustion engine, includes a journal bearing that may be attached to a supporting foundation and a support that may be attached to the engine. An elastic spring is connected between the journal bearing and the support while a bearing spring made of a non-creeping material is connected between the journal bearing and the support in parallel with the elastic spring. The bearing spring comprises at least one disk spring having an S-shaped spring constant curve. The disk spring and the elastic spring have load carrying capacities such that, after the weight of the body to be supported is applied to the flexible bearing, the spring rate of the disk spring is essentially zero and the rubber spring is essentially free of elastic tensions.
