Abstract

A compensation device has a ring-shaped body ( 10 ). The ring-shaped body ( 10 ) has an inner side ( 13 ) facing towards a center of the ring-shaped body ( 10 ) and an outer side ( 11 ) facing away from the center of the ring-shaped body ( 10 ). At least a beveled part ( 15 ) of the inner side ( 13 ) includes an acute angle with an axis (X) of the ring-shaped body ( 10 ). At least three flexible elements protrude from the beveled part ( 15 ) and are distributed around the circumference of the ring-shaped body ( 10 ).

Claims (24)

1. A compensation device comprising

a ring-shaped body,

an inner side facing towards a center of the ring-shaped body and an outer side facing away from the center of the ring-shaped body, wherein at least a beveled part of the inner side includes an acute angle with an axis of the ring-shaped body, and

at least three flexible elements which protrude from the beveled part and which are distributed around the circumference of the ring-shaped body, wherein the ring-shaped body has at least three recesses which extend from the beveled part of the inner side into the ring-shaped body and which take in at least a part of the flexible elements.

2. The compensation device according to claim 1 , wherein the flexible elements protrude from the ring-shaped body rectangular to the beveled part of the inner side of the ring-shaped body.

3. The compensation device according to claim 1 , wherein each flexible element comprises a spring which is arranged in each recess of the ring-shaped body and a sphere which protrudes from each recess of the ring-shaped body and which is coupled to the spring.

4. A cylinder head arrangement comprising:

a Belleville spring washer or a compensation device comprising:

a ring-shaped body,

an inner side facing towards a center of the ring-shaped body and an outer side facing away from the center of the ring-shaped body, wherein at least a beveled part of the inner side includes an acute angle with an axis of the ring-shaped body, and

at least three flexible elements which protrude from the beveled part and which are distributed around the circumference of the ring-shaped body, wherein the ring-shaped body has at least three recesses which extend from the beveled part of the inner side into the ring-shaped body and which take in at least a part of the flexible elements,

a cylinder head having a recess,

an injector being arranged in the recess of the cylinder head, the recess of the cylinder head comprising an injector seat for the injector, wherein the compensation device or the Belleville spring washer, respectively, being circumferentially arranged around an axial section of the injector and between the injector and the injector seat.

5. The cylinder head arrangement according to claim 4 , wherein the flexible elements protrude from the ring-shaped body rectangular to the beveled part of the inner side of the ring-shaped body.

6. The cylinder head arrangement according to claim 4 , wherein each flexible element comprises a spring which is arranged in each recess of the ring-shaped body and a sphere which protrudes from each recess of the ring-shaped body and which is coupled to the spring.

7. A cylinder head arrangement comprising:

a compensation device comprising:

a ring-shaped body,

an inner side facing towards a center of the ring-shaped body and an outer side facing away from the center of the ring-shaped body, wherein at least a beveled part of the inner side includes an acute angle with an axis of the ring-shaped body, and

at least three flexible elements which protrude from the beveled part and which are distributed around the circumference of the ring-shaped body, wherein the ring-shaped body has at least three recesses which extend from the beveled part of the inner side into the ring-shaped body and which take in at least a part of the flexible elements,

a cylinder head having a recess,

an injector being arranged in the recess of the cylinder head, the recess of the cylinder head comprising an injector seat for the injector, wherein the compensation device is circumferentially arranged around an axial section of the injector and between the injector and the injector seat.

8. The cylinder head arrangement according to claim 7 , wherein the flexible elements protrude from the ring-shaped body rectangular to the beveled part of the inner side of the ring-shaped body.

9. The cylinder head arrangement according to claim 7 , wherein each flexible element comprises a spring which is arranged in each recess of the ring-shaped body and a sphere which protrudes from each recess of the ring-shaped body and which is coupled to the spring.
