COMBUSTION CHAMBER AND DRIVE-IN DEVICE
First Claim
1. A combustion chamber comprising a combustion chamber wall in a form of a hollow cylinder that defines a cylinder axis;
- a bottom that is adjustable along the cylinder axis within the hollow cylinder relative to the combustion chamber wall; and
a seal, which lies against the bottom on the one side of the seal and against the combustion chamber wall on the other side of the seal, in a radial direction with reference to the cylinder axis, wherein the seal comprises a first seal ring that extends in the circumferential direction with reference to the cylinder axis and has a first interruption, and a second seal ring having a second interruption, the second seal ring extending in the circumferential direction with reference to the cylinder axis, wherein the first interruption has a first angular position along the circumferential direction and the second interruption has a second angular position along the circumferential direction, wherein the first angular position and the second angular position form an angle that is greater than 0° and
less than 180°

Abstract
A combustion chamber has a combustion chamber wall formed as a hollow cylinder defining a cylinder axis, a bottom that is adjustable along the cylinder axis within the hollow cylinder, relative to the combustion chamber wall, and a seal, which lies against the bottom on the one side and against the combustion chamber wall on the other side, in a radial direction with reference to the cylinder axis. The seal comprises a first seal ring extending in the circumferential direction with reference to the cylinder axis and has a first interruption, and a second seal ring extending in the circumferential direction with reference to the cylinder axis and has a second interruption. The first interruption has a first angular position along the circumferential direction, and the second interruption has a second angular position along the circumferential direction, wherein the first angular position and the second angular position form an angle.
