Adsorbent cartridge

摘要

An adsorbent cartridge for mounting in a housing including a casing consisting of an end wall and a cup-shaped member having a flexible substantially cylindrical wall, with the end wall and the cylindrical wall having their edge portions fused to each other to provide a radially outwardly extending rim for sealing engagement with the housing of a filter-drier, adsorbent in the housing, and the flexible cylindrical wall being adapted to bulge into sealing engagement with the housing when opposing forces directed toward each other are applied to the end wall and the bottom of the cup-shaped member. An adsorbent cartridge having the above structure and including an axially extending pipe fused to the end wall and the opposite end wall of the cup-shaped casing so as to provide an annular chamber for adsorbent, with the end walls extending radially inwardly beyond the pipe to provide rims for sealing engagement with a pipe member passing through the pipe of the adsorbent cartridge.
