Separation device for separating a working chamber and a compensation chamber of a hydraulically damping mount, and a hydraulically damping mount

1. A separation device for separating a working chamber and a compensation chamber of a hydraulically damping mount, the separation device comprising:

a first nozzle disc; and

a second nozzle disc;

wherein the first nozzle disc and the second nozzle disc are made of a first material and form a damping channel that interconnects the working chamber and the compensation chamber,

wherein the first nozzle disc comprises a sealing member made of a second material and abuts the second nozzle disc to seal the damping channel,

wherein the second nozzle disc has a receiving opening into which the first nozzle disc is inserted; and

wherein the receiving opening has a circumferential shoulder against which the sealing member abuts.

2. The separation device according to claim 1 , wherein the first nozzle disc and the sealing member are manufactured using a two-component injection moulding process.

3. The separation device according to claim 1 , wherein the first material is a fibre-reinforced plastic; and the second material is a thermoplastic elastomer.

4. The separation device according to claim 1 , wherein the sealing member surrounds the first nozzle disc on an outer circumferential side.

5. The separation device according to claim 1 , wherein the receiving opening has a circumferential shoulder against which the sealing member abuts.

6. The separation device according to claim 5 , including a channel formed by a first channel section and a second channel section which are separated from one another by the first nozzle disc and sealed from one another by means of the sealing member.

7. The separation device according to claim 6 , wherein the first nozzle disc has the channel on an outer circumferential side which abuts against the inner circumferential wall of the receiving opening in order to form the first channel section; the channel has a first leg, a second leg, and a base interconnecting the two legs; and the sealing member is arranged at a free end of the first leg.

8. The separation device according to claim 1 , wherein a diaphragm is received between the nozzle discs.

9. A hydraulically damping mount for mounting a motor vehicle unit, the hydraulically damping mount comprising:

a support, and

a supporting mount connected to the support by a supporting spring made of an elastomeric material,

wherein the supporting spring delimits the working chamber which is separated from the compensation chamber by the separation device according to claim 1 , and

the working chamber and the compensation chamber are filled with a fluid and are connected to one another via the damping channel.
