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.
