摘要

Flexible cleaning piston has one or more circular cambers at the outer periphery. The cambers bear a balanced flexible adjustment pressure all around and consists of flexible, form-stable materials, e.g. plastic, rubber or natural rubber. Materials can flexibly adapt with pressure shifting into the tubing inner profile.
