An L-shaped sealing ring comprising two legs connected with one another to form an L-shape in cross section. A length of a first leg is part of a lateral surface of revolution about an axis of the L-shaped sealing ring. The first leg lies between the first length and the axis of revolution. A second leg is bounded toward the environment by a second length, wherein the first and second lengths are connected with one another via a connection contour. An intersection of first and second lines, forms a corner of a triangle, wherein the respective end points of the first and second lengths form other vertices of the triangle. The L-shaped sealing ring is so embodied that the surface area of the cross sectional area of the body of the L-shaped sealing ring in the triangle amounts to, at most, 60% of the areal content of the triangle, wherein the area of the L-shaped sealing ring in the triangle is non-concave.
