Abstract

A hydromount suitable for mounting a motor vehicle engine on a vehicle body includes: a load-supporting spring that supports a mount core, encloses a working chamber, and is supported on an outer ring, an intermediate plate, and a compensation chamber separated from the working chamber by the intermediate plate and delimited by a compensation diaphragm. The compensation chamber and the working chamber are filled with a damping liquid and are connected with each other in a liquid-conducting manner via a damping channel disposed in the intermediate plate. The intermediate plate may include an upper nozzle disk, a lower nozzle disk, and a diaphragm disposed between the upper nozzle disk and the lower nozzle disk. The diaphragm may have an inner circumference, an outer circumference, and at least one valve opening. The at least one valve opening may be disposed completely between the inner circumference and the outer circumference.
