1. A flow device, comprising:
an inlet;
an outlet;
a first fluid flow path hydraulically connected in parallel to the inlet and the outlet;
a second fluid flow path hydraulically connected in parallel to the inlet and the outlet;
a first loop in the first flow path directed in a reverse flow direction of the first fluid flow path;
a second loop in the second flow path directed in a reverse flow direction of the second fluid flow path; and
an interconnecting path directing reverse flow from the first loop into forward flow of the second flow path and against the reverse flow direction of the second loop,
wherein
the first fluid flow path and the second fluid flow path have a first hydraulic resistance in a forward flow direction and a second hydraulic resistance in a reverse flow direction, and
the second hydraulic resistance is greater than the first hydraulic resistance.
