  • Patent number: 4834348
    Abstract: A support bearing with fluid damping in a housing which includes two chambers which are of variable volume and filled with a fluid, and are interconnected by a passage with a built-in restrictor valve. The housing includes rubber-elastic inner and outer walls of different degrees of hardness which are fastened to metallic support members. One of the supports is connected with the foundation and the other with the part (engine) to be supported. One chamber surrounds the other chamber circularly and a passage interconnects the chambers. The walls defining the chambers are incorporated in a housing connected to a support member. The elements comprises a rubber-elastic material and are formed in one piece and are firmly connected with the one supporting member, as well as with a support ring, which is advantageously connected with the other supporting member by mechanical means.

  • Patent number: 4805884
    Abstract: A dual-chamber support bed with hydraulic cushioning especially for engine mount in motor vehicles includes a working chamber and a compensating chamber filled with liquid have walls (3, 4) comprising annular rubber diaphragms with a predetermined buckling characteristic to adapt to the operating load the chambers are connected to one another through a nozzle channel. The nozzle channel is defined between profiled parts overlapping one another which are two rigid components of a housing that are adjustable to one another. The channel flow resistance is adjustable by means of a screw-driven regulating unit. The two components forming the nozzle channel there between are adjustable axially relative to one another in the direction of the vertical axis of the mount. One of these components is thread onto a spindle that can rotate freely in the housing. An operating member for rotating the spindle extends out of the housing, and can be screwed on it coaxially with the vertical axis.

  • Patent number: 4730584
    Abstract: A dual-chamber support bed or motor vehicle engine mount with hydraulic cushioning includes a resilient housing part and a support base for use in defining a working chamber and compensating chamber filled with liquid, the housing walls are annular rubber diaphragms with a buckling characteristic that is adjustable to adapt to the operating load. The chambers are connected to one another through a nozzle channel. Means for controlling the buckling characteristics (buckling rigidity) are provided in a wall of the working chamber and in a preferred embodiment include an additional buckling spring that is clamped into the fixed base housing and is adjustable in its buckling behavior from the exterior by a spindle.
