Abstract

L'invention consiste essentiellement à réaliser le man­ chon de travail du cylindre de pression en deux parties distinctes, à savoir une partie intérieure (2) fixée à demeure sur les coussinets usuels (3, 4), et une partie extérieure (1) rapportée sur la première afin d'être susceptible d'être aisément remplacée après usure. The invention essentially consists in carrying out the man two-piece pressure cylinder work separate, namely an interior part (2) permanently fixed on the usual bearings (3, 4), and an outer part (1) reported on the first in order to be likely to be easily replaced after wear.
