Abstract
A flow switch device includes a flow switch with four ports oriented at 90 degree intervals around a center of the flow switch. The flow switch is of a type that forms selectable flow passages between ports separated by 90 degrees and blocks flow between ports separated by 180 degrees in each of multiple selected positions. Two of the ports are connected to fixed flow passages and each of the fixed flow passages defines a flow path toward a remote port separated from each of the fixed flow passages by 180 degrees so that each of the fixed flow passages and a respective remote port are positioned in pairs on opposite sides of the flow switch.
