## 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.

## Claims

### Claim at position 1

-9. (canceled)

### Claim 10

A hydromount for mounting a motor vehicle engine on a vehicle body, comprising:
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 which is separated from the working chamber by the intermediate plate and is delimited by a compensation diaphragm,
wherein 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 has an upper nozzle disk, a lower nozzle disk, and a diaphragm disposed between the upper nozzle disk and the lower nozzle disk; the diaphragm has an inner circumference, an outer circumference, and at least one valve opening; and the at least one valve opening is disposed completely between the inner circumference and the outer circumference.

### Claim 11 (depends on 1)

The hydromount according to claim 1, wherein the lower nozzle disk has an accommodating portion for accommodating the diaphragm that comprises a nozzle assembly and a material portion.

### Claim 12 (depends on 11)

The hydromount according to claim 11, wherein the material portion has at least one projection configured to engage with the valve opening of the diaphragm.

### Claim 13 (depends on 10)

The hydromount according to claim 10, wherein the lower nozzle disk has at least one centering pin and the upper nozzle disk has at least one centering opening, and the at least one centering pin is configured to be inserted into the at least one centering opening.

### Claim 14 (depends on 10)

The hydromount according to claim 10, wherein the valve opening is formed as an elongated hole.

### Claim 15 (depends on 10)

The hydromount according to claim 10, wherein the longitudinal axis of the valve opening is offset relative to the radial direction.

### Claim 16 (depends on 10)

The hydromount according to claim 10, wherein the diaphragm is fixed between the upper nozzle disk and the lower nozzle disk with axial clearance.

### Claim 17 (depends on 10)

The hydromount according to claim 10, wherein the diaphragm is made from an elastic material.

### Claim 18 (depends on 10)

The hydromount according to claim 10, wherein the diaphragm has a surface structure.

### Claim 19 (depends on 10)

The hydromount according to claim 10, wherein the surface structure is formed in a nubbed manner.
