Abstract (en)
[origin: DE102011007729B3] The press plate (10) includes a filler piece (20) having a pressing surface (21), which is tapered at the outer diameter, such that an outer conical surface (22) is formed. A sealing ring (30) is formed around the inner diameter of the press plate such that a radial gap (61) is formed between the inner conical surface and the outer conical surface of the filler piece. The radial gap is extended conically outwards between the filler piece and the sealing ring, such that a peripheral puncture (31) is formed in the periphery of the radial gap.
