Title:
高圧バレル
Document Type and Number:
Japanese Patent JP7235888
Kind Code:
B2
Abstract:
The present invention provides a high-pressure piston-cylinder assembly for compaction treatment comprising a cylinder comprising a plurality of sections which are longitudinally stacked and joined to form the cylinder; a piston configured for moving in and along the cylinder; and a base configured for being coupled with the cylinder to provide mechanical support to the cylinder; wherein each of the sections includes one or more releasing channels for releasing of liquid or gas fluid generated during compaction treatment. The high-pressure piston-cylinder assembly is sealed by one seal having a helical coiled sealing ring structure tightly encircling the piston, and another seal encircling a cylindrical sealing block protruded from the base and into the cylinder. The resulting piston-cylinder assembly can be more effectively manufactured, has better durability and tolerance in high-pressure operation.
