ABSTRACT:
A strainer assembly for removing solid particulates from a fluid has a housing shaped as an elbow-shaped conduit and a support member for supporting a screen adjacent a forwardly extending flange on an inlet conduit section of the housing, the housing also comprising an enlarged intermediate section, in which the support member is disposed, and an outlet conduit section. The support member is threadedly engaged in a wall of the enlarged intermediate section of the housing and preferably has a base and a plurality of posts extending from the base, with the screen seated on the distal ends of the posts. Fluid entering the housing through the inlet section passes through the screen and then through passageways between the posts of the support member and is then discharged from the housing through the outlet conduit section.
