ABSTRACT:
A filter-drier unit adapted for bidirectional flow in heat pump systems. This filter-drier unit includes a shell having opposed flow ports. Spaced partitions in the shell provide a compartment therebetween, each partition separating a flow port from the compartment. An outlet check valve is connected to each partition, and a perforated tube in the compartment, extends between and interconnects the outlet check valves. A molded desiccant core in the compartment, is disposed about the tube. An inlet check valve is connected to each partition in laterally spaced relation to the outlet check valve connected to the same partition to control the flow from each flow port through an inlet check valve in one partition and into the compartment, through the core and tube thence through an outlet check valve in the other partition, and out the other flow port.
