ABSTRACT:
The invention is directed to a non-clogging flow restrictor for use in a faucet. The flow restrictor is slotted with the sides of the narrow slots either parallel to each other or divergent from each other relative to the entrance side of the respective slot. However, the length of the slots on the entrance side is considerably longer than the length of the slots on the exiting side of the restrictor. Because of this, the invention can tolerate a substantial collection of particles at the leading or flow entry edges of the slot or slots without affecting the designed flow rate.
