摘要: A shaft sealing structure (12) includes a plurality of V-packings (14a to 14c) that are stacked in multiple stages, and each of the V-packings is formed of a thick-walled annular top portion (16), a thin-walled inner side skirt portion (18), and a thin-walled outer side skirt portion (20). Adjacent ones of the top portions abut against each other, adjacent ones of the inner side skirt portions do not interfere with each other, and adjacent ones of the outer side skirt portions do not interfere with each other.

摘要: The present invention addresses the problem of stabilizing the state of assembly of a seal member while allowing movement of a piston member in a direction that reduces one space inside a cylinder member with little resistance. The seal member 3 includes a base portion 3a located towards the one space 5, which is a first space inside the cylinder member 2, and an extending portion 3b extending from the base portion 3a toward the other space 6, which is the second space inside the cylinder member 2. The piston member 1 is provided with a first holding portion 1a that faces the base portion 3a of the sealing member 3, a second holding portion 1b that faces an extended edge 3i of the extended portion 3b of the sealing member 3, and a third holding portion 1c that faces a held part 3k formed on the inside of the extended portion 3b of the seal member 3. A fluid passage 1g is formed in the second holding portion 1b.

摘要: The invention relates to a shaft-sealing arrangement (11) comprising a first seal and a second seal, wherein the first seal is designed in the form of a lip seal (5) and the second seal is designed in the form of a mechanical seal (25), wherein, when the shaft is at a standstill, the lip seal performs the sealing action and, when the shaft is rotating (operational state), the mechanical seal (25) performs the sealing action.
