Abstract
Un corpo interstadio realizzato in lamiera metallica include un elemento a forma di recipiente cilindrico avente ad un'estremità una parete di fondo e all'estremità opposta una parete aperta. Quest'ultima ha una superficie terminale assiale ed una superficie radialmente interna che realizzano un giunto a bicchiere accoppiabile con un corpo interstadio successivo.L'elemento a forma di recipiente cilindrico include una parete laterale cilindrica, una porzione cilindrica unita tra la parete di fondo e la parete laterale cilindrica ed avente un diametro esterno leggermente inferiore del diametro interno dell'estremità aperta, ed una porzione piana unita alla porzione ribassata che serve da superficie terminale della parete di fondo. La porzione piana ha un diametro esterno leggermente inferiore del diametro esterno dell'estremità aperta. Il corpo interstadio inoltre include una porzione ribassata unita alla porzione cilindrica ed avente un diametro inferiore della porzione cilindrica stessa. La porzione ribassata prevede uno spazio per alloggiare un O-ring.
