Field: Mechanical elements (Mechanical engineering)
Classification: CPC F | IPC F

Claim 0:
1. A seal assembly, comprising:
a first and a second machine element which, while forming a seal gap arranged between the two machine elements, are spaced apart from one another and are movable relative to one another along/about a movement axis;
a seal for sealing a high-pressure side H of the seal gap which can be pressurized with a fluid against a low-pressure side N of the seal gap; and
a support ring with a first side edge facing the high-pressure side H which is at least partially convexly curved or which is formed obliquely towards the high-pressure side H or at least partially formed at an acute angle α relative to the axis of movement of the two machine elements;
wherein the seal has a retaining portion and at least one primary sealing lip extending on the high-pressure side from the retaining portion and abuts in a dynamically sealing manner against a sealing surface of the second machine element;
wherein the primary sealing lip directly abuts and is supported over the majority of its longitudinal extent on the first side edge of the support ring on the high-pressure side; and
wherein the seal comprises a wiper or secondary sealing lip which abuts the sealing surface of the second machine element, wherein the support ring has a second side edge facing the low-pressure side N which is at least partially convexly curved or which is formed at an acute angle β relative to the axis of movement and wherein the wiper or secondary sealing lip directly abuts and is supported on the second side edge of the support ring, and wherein the retaining portion of the seal is held clamped between the support ring and the first machine element and abuts the first machine element in a statically or indirectly statically sealing manner;
wherein the support ring is spaced apart from the second machine element in normal operation of the seal assembly, wherein the seal is one piece, wherein a tension disk made of an elastic deformable material is arranged between the support ring and the first machine element, wherein said tension disk is in direct contact with and abuts the first machine element in a statically sealing manner, and wherein the seal is tensioned against the support ring by the tension disk at least partially in a radial and in an axial direction.
