is opposite to the imbalance 10 as depicted in fig1 and 2 as viewed in radial direction from inside to outside the interior space 28 expands in axial direction as a consequence of the slanted transition 22 this is advantageous during assembly of the compensation disk 1 as damping fluid such as oil will not leak and is safely retained in the formed depression of the ring shaped interior space 28 in addition the ball members 11 are securely guided in radial direction by the formed narrowing of the ring shaped interior space 28 as further shown in fig1 and 3 the fluid tightness of the compensation disk 1 to the outside is realized by incorporating a sealing arrangement between the half shells 2 3 including a first sealing ring 26 such as an o ring disposed between the stepped offset 15 of the half shell 2 and the juncture area between the sleeve portion 20 and disk shaped ring 21 of the second half shell 3 a second sealing ring 27 such as an o ring is disposed between the sleeve portion 18 of the half shell 2 and the sleeve portion 24 of the half shell 3 and is pressed by the flange 25 against the sleeve portion 18 suitably the half shell 2 is formed in the area of the sleeve portion 18 with a circumferential groove 29 so that the sealing ring 27 can be slightly press fitted between the groove 29 and the sleeve portion 24 of the half shell 3 before the end of the sleeve portion 24 is turned inwards to form the flange 25 assembly of the compensation disk 1 will now be described with reference to fig4 to 9 fig4.
