Abstract
An expansion/check valve assembly is provided that includes a reverse flow rate adjustment device that allows for adjustment of the flow rate of a fluid flowing reversely through an open check valve port. The adjustment device includes a flow rate control member within the valve body and an adjustment member accessible outside of the valve body. The flow rate control member is operably coupled to the adjustment member and the adjustment member preferably includes a visual indicator viewable outside of the valve body to indicate the position of the flow rate control member. When installed in a refrigeration system at the inlet of the evaporator, the reverse flow rate adjustment device can be adjusted to control defrost conditions.
