Claim:
1. A turbomachine comprising: a flow channel; a housing radially surrounding the flow channel; at least one liner being situated between the flow channel and the housing; a stator shroud spaced apart from the at least one liner in a radial direction; a rotor shroud spaced apart from the at least one liner in the radial direction; and at least one clamping ring situated at least partially circumferentially around the flow channel to abut at least one contact surface of the at least liner; wherein the clamping ring includes an outer ring and an inner ring spaced a distance apart in the radial direction; wherein the outer ring and the inner ring are connected to each other via an annular web situated on a same side of front edges of the outer and inner rings to form a cross-sectional C-shape; wherein the contact surface of the liner abuts a radially outer surface of the inner ring; wherein the inner ring, outer ring, and annular web are positioned such that, during operation of the turbomachine, thermal expansion due to heating of the inner ring results in the inner ring being moved radially outward towards the outer ring to press against the contact surface of the liner sealing the flow channel.
