Cylinder for producing high dynamic pressure, is encased by another cylinder, where seal present between two cylinders is divided into two sections, and pressure between two sections is led into space between two cylinders

摘要

The cylinder (3) is encased by another cylinder (6), where a seal (7) is present between the two cylinders and is divided into two sections (1, 2). The pressure between the two sections is led into a space between the two cylinders. The space between the two cylinders is filled by screw threads, such that both a static and a dynamic hoop is developed. The cylinder (6) is loaded dynamically only by an intermediate pressure.
