Fluid cushioning mounting particularly for engines in motor vehicles

Claim 1

A dual-chamber support bed with hydraulic cushioning for engine mount vehicles, having a working chamber and a compensating chamber filled with liquid, and walls defining said chambers made of annular rubber diaphragms having a predetermined buckling characteristics adapted to an operating load, and being connected to a housing, first and second rigid components of said housing overlapping one another and forming a nozzle chamber, said first and second rigid components of said housing being adjustable relative to one another, a rotatable spindle supported in said second component, said channel having a flow resistance which is adjustable by means of a regulating unit connected to said spindle, said first and second components being adjustable relative to one another in the direction of the vertical axis of the mount, and one of said components being threaded on said spindle which is rotatable freely in said housing, and said unit including an operating member extending out of said housing, said nozzle channel being positioned concentrically to the vertical axis in a plane perpendicular to it, said one component having a raised profile engaged in a corresponding die profile of said other component and being adjustable in this profile, said nozzle channel having a raised die profile which is connected by openings to the working chamber and to the compensating chamber and is sealed by means of an elastic diaphragm, and the raised profile of the component is adjustable relative to said diaphragm.
