Reversing valve assembly with improved pilot valve mounting structure

Abstract

A refrigerant reversing valve assembly comprising a refrigerant reversing valve including a fluid pressure actuable reversing valving member for reversing the direction of refrigerant flow in a refrigeration system, a pilot valve unit for controlling actuation of the valving member comprising a pilot valve housing in fluid communication with the reversing valving member, an actuable pilot valving member in the housing, and pilot valve actuating means comprising a pilot valving actuating member plunger coupled to the pilot valving member, a guide tube surrounding the plunger connected to the pilot valve body and projecting therefrom, and a solenoid surrounding the guide tube for actuating the plunger, and supporting structure for interconnecting the reversing valve and the pilot valve unit. The supporting structure includes an anchoring panel rigidly fixed with respect to the reversing valve and rigidly fixed to the pilot valve unit for securing the reversing valve and pilot valve unit together with the plunger guide tube projecting away from the anchoring panel in a first direction, a rigid retainer panel detachably connected to the guide tube projecting end remote from the anchoring panel for maintaining said solenoid in position with respect to said guide tube between the panels, and coupling panels engaged between the anchoring and retainer panels.
