Abstract

A mounting device, in particular to the mounting of an internal combustion engine on a chassis of a motor vehicle, which is provided with a fluid working chamber that is fluidically connected via at least one fluid channel to a fluid equalization chamber via at least one fluid channel in a housing. At the same time, a fluid damping chamber is provided, which is separated by an elastic membrane from the fluid working chamber and which is connected with fluidic connection via a throttling channel to an outer environment of the mounting device. The throttling channel is formed by a replaceable throttling element separately from the housing.

Claims

1. A mounting device for damping of the mounting of an assembly in a car body of a motor vehicle, comprising:

a fluid working chamber which is fluidically connected by at least one fluid channel to a fluid equalization chamber provided for the mounting device in a housing, wherein a fluid damping chamber is separated by an elastic membrane from the fluid working chamber, and is fluidically connected to an outer environment of the mounting device via a throttling channel, wherein the throttling channel is formed within an exchangeable throttling element, which is separate from the housing, and which is arranged in a retaining element which is releasably secured to the housing,

wherein the fluid working chamber and the fluid equalization chamber are separated by a separating element, wherein the at least one fluid channel is formed in the separating element by which the fluid working chamber and the fluid equalization chamber are in a fluidic connection,

wherein the housing is provided with a flow channel, which is fluidically connected to the fluid damping chamber and in which the throttling element is at least partially arranged

wherein the flow channel opens directly into the fluid damping chamber, wherein the housing passes through the separating element.

2. The mounting device according to claim 1, wherein the fluid damping chamber is arranged in the separating element and the membrane is fastened on the separating element.

3. The mounting device according to claim 1, wherein the retaining element is secured to the housing with latching and a supporting element of the retaining element receiving the throttling element is interposed in the flow channel.

4. The mounting device according to claim 1, wherein the flow channel is provided with an at least partially conical inner circumference surface.

5. The mounting device according to claim 4, wherein the throttling element is provided at its end which is arranged in the flow channel with a retaining projection, wherein a seal is arranged between the retaining projection and the supporting element.

6. The mounting device according to claim 5, wherein the seal is placed on the inner circumference surface of the flow channel.

7. The mounting device according to claim 1, wherein a first mounting position is arranged on a mounting cover delimiting the fluid working chamber together with the separating element and a second mounting position is connected with the housing.
