Abstract

a presente invenção refere-se a um ajustador de folga que é protegido contra contaminantes ambientais, através de uma série de orifícios posicionados circunferencialmente em torno de cada extremidade, e cobertos por uma bucha que tem uma fenda, sendo alinhado com um da série de orifícios, enquanto cobre os orifícios remanescentes. a bucha protege contra infiltração de contaminantes nas extremidades do ajustador de folga, e permite que quaisquer contaminantes que se infiltrem no ajustador de folga, seja expelido através do orifício e da folga alinhados. a porção central do ajustador de folga pode também ser protegida incluindo uma série de orifícios circunferenciais, que são seletivamente cobertos por uma bucha que tem uma drenagem posicionada para se alinhar com os orifícios menores, enquanto cobre os orifícios remanescentes.The present invention relates to a slack adjuster that is protected against environmental contaminants through a series of holes circumferentially positioned around each end and covered by a slotted bushing being aligned with one of the series of holes. while covering the remaining holes. The bushing protects against contaminant seepage at the ends of the clearance adjuster, and allows any contaminants that seep into the clearance adjuster to be expelled through the aligned hole and clearance. The central portion of the clearance adjuster may also be protected by including a series of circumferential holes, which are selectively covered by a sleeve having a drainage positioned to align with the smaller holes while covering the remaining holes.
