Abstract
Dispositif et méthode de freinage servant à ralentir et/ou à arrêter un transporteur pneumatique à l'intérieur d'un système de transport pneumatique. Le dispositif comporte habituellement un tube pneumatique dont la taille permet le passage de transporteurs pneumatiques. Le tube pneumatique comprend au moins un élément de freinage qui peut être placé à l'intérieur de façon à empêcher partiellement un transporteur pneumatique de passer. Dans un modèle, le dispositif de freinage est une section de dimension variable du tube pneumatique qui peut être étranglé d'une façon sélective pour changer le diamètre du tube pneumatique. Cet étranglement peut ralentir et/ou arrêter le passage d'un transporteur pneumatique dans le tube pneumatique.
