Abstract
This inlet strainer (160) is for a thermostatic expansion valve (100) having an inlet fitting (114). The inlet fitting 114 includes an elongate passage (152), with an inlet opening at one end and a strainer-receiving opening at the other end, and a transverse passage (156) communicating with the elongate passage (152) between said ends. The strainer assembly (160) includes a closed outer end (162) threadedly connected to the fitting (114), a strainer tube (164) extending into the elongate passage (152) to a point beyond the transverse passage (156) and a closure ring (166) received in sliding relation within the passage (152) so that dirt is removed from the refrigerant before entering the valve port.
