best seen in fig3 are heat sealed to each other and are joined by a web 31 which partially encircles the screen 25 each bag contains a dessicant 32 such for example molecular sieve an important feature of the invention resides in the provision of a deflector for the accumulator dehydrator which is of unique construction and which can be assembled with the upper cap in a unique manner without the aid of extraneous fasteners the deflector d is clearly illustrated in fig3 6 7 8 9 and 10 the deflector d is preferably made in one piece as a metal stamping stamped or formed to provide a flat elongated body 33 having downturned flanges 34 and 35 at its side edges and an arcuate flange 36 at one end as seen in fig7 the flange 36 extends inwardly beyond the edges of the flanges 34 and 35 to thereby form a tenon whereby the deflector d may be attached to the cap 1 flange 36 has an arcuate extent of less than 360 u00b0 in assembling the deflect d with the cap 1 and the fitting 14 the flange 36 is inserted between the surface of the cap 1 defining the hole 7 in the cap and the portion of the fitting 14 which extends into the hole 7 the engagement of these three parts acts not only to hold.
