Abstract

Vérin d’une installation agroalimentaire. Vérin (1) d’une installation agroalimentaire (2) comportant un piston (3) poursuivi par une tige (30) et un élément cylindrique (4) comportant une paroi périphérique (42) délimitant une chambre (5) dans laquelle est guidé le piston (3), configuré en sorte de fonctionner sans grippage pour une température de fonctionnement entre 5°C et 35°C, la température interne de l’élément cylindrique (4) restant à la température de fonctionnement lors d’un fonctionnement pendant une opération de nettoyage à une température d’au moins 75°C durant un temps de nettoyage, une épaisseur de paroi (42) dudit élément cylindrique (4) étant surdimensionnée par rapport à des exigences de guidage dudit piston (3) et à des exigences de résistance à la pression d’un fluide hydraulique, ladite épaisseur de paroi (42) étant supérieure à 8 millimètres tandis que le rapport de l’épaisseur de paroi (42) divisé par le rayon (r) de l’élément cylindrique (4) est supérieur à 0,1. Figure de l’abrégé : Figure 1.
