ABSTRACT:
The present invention provides a flow restricter for use in fluid flow systems, for example, shower head assemblies. The flow restricter comprises a conical member having a plurality of slotted openings along the length thereof. The slotted openings are in fluid communication with an outlet of a size desired to provide a limited flow through the restricter. The conical member in the preferred embodiment is upstream of the outlet opening. The use of a plurality of slotted openings to provide fluid communication to an outlet opening eliminates the possibility of single point failure of the present invention. The conical member is tapered so that, when disposed in a fluid delivery system, a contaminant reservoir is formed around the conical member. In this manner, ever when the reservoir is full of contaminant particles, water will flow through the contaminants without disrupting the flow requirements.
