发明名称 Seal arrangement for vacuum device
摘要 The arrangement comprises a toroidal sealing ring (6) which is placed within a groove (5) of the vacuum chamber wall (3) that will be covers by a lid (4). The sides (7,8) of the groove are inclined inwards, relative to the groove base (10) so that a triangular cross section is formed. The triangle is equilateral, its base being formed by the groove base and its height being approximately twice the groove depth. On the area of the side angles of the triangle, the groove is rounded, forming a circumscribed angle on each corner, where the ratio of the circle diameter to the groove depth is 1:1.42. The ratio of the sealing ring diameter (B) to the groove depth is 1:1.35. Under compression from a second overhead component against which the seal is to be effected, the sealing ring flattens against the three surfaces of the groove so as to create the seal.
