Abstract

"ATUADOR DE FREIO DE MOLA E MéTODO PARA FORMá-LO". Um pequeno invólucro é obtido para uma conexão deformada inelasticamente entre uma cobertura de mola (22) e um alojamento central em um atuador de freio de mola. A conexão é deformada radialmente interiormente (32) e então se estende radialmente exteriormente (31) a partir da porção que se estende radialmente interiormente. Isto elimina a porção que se estende radialmente exteriormente e flanques como são tipicamente utilizados na técnica anterior. Portanto, um invólucro muito menor é provido. Em configurações preferidas desta invenção, uma ranhura de vedação (36) é posicionada axialmente adjacente a uma ranhura de retenção no alojamento central. Uma vedação (34) é posicionada na ranhura de vedação para assegurar uma vedação hermética. Além disto, uma estrutura guia de diafragma de única
