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.

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.

Two chamber engine mount

A two-chamber engine mount with hydraulic damping has a partition arranged between a working space and an equalization space. The partition is formed in a first subarea by a disc movable between stops. The play of the disc between the stops can be varied by a motor. In a second subarea, the partition is penetrated by a first choke canal. A second choke canal can be added to the first choke canal in series or parallel therewith by a motor.

A vibration damper for bodies which extend substantially parallel to one another, consisting of a clip made of a permanently elastic material and adapted to be slipped undislodgeably onto one of the bodies, and of at least two lugs projecting therefrom in the direction of at least one further body which clasp the latter with elastic initial tension, permitting relative displacement.

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.
