摘要:
The invention relates to a shaft passage and a valve having such a shaft passage, as well as a method for producing a shaft passage, in which the shaft (21) has at least one drive portion (24) to which a drive for controlling the shaft (21) can be connected and has a connecting portion (25) opposite the drive portion (24), to which an actuating member (64) can be connected, and an inner shaft portion (26) in the through-bore (22) extending at least partially in the through bore (22), and having an inner shaft seal (36) to which an operating pressure of a medium to be controlled by the actuating member (64) is applied, and having a fluid shaft seal (34) which extends in the direction of the drive portion (24), and which is arranged between the inner shaft seal (34) and the outer shaft seal (42), wherein the fluid shaft seal (34) is formed between the through bore (22) and the inner shaft portion (26) of the shaft (21) and is pressure-relieved against an operating pressure of the medium to be controlled.
