1. A tilting pad bearing for supporting a shaft with a longitudinal axis, comprising:
at least two tilting pads spaced apart from each other, each of which has a bearing surface,
at least one hot oil drainer which is arranged in an intermediate space between the at least two tilting pads, and
at least one force application element for applying a force acting radially inwards on the at least one hot oil drainer,
wherein the at least one hot oil drainer is mounted such that it is moveable towards and away from the shaft, and
wherein the at least one hot oil drainer comprises at least one dam and at least one oil injection device for spraying oil onto the shaft supported in the tilting pad bearing, and
wherein the at least one force application element comprises at least one hydraulic element which utilizes oil in the at least one hot oil drainer as a hydraulic fluid.
