ABSTRACT:
A pressure compensating flow control device includes a generally elongated, collapsible tubular body of flexible material such as silicone rubber having a teardrop shaped inlet orifice for extending into a high pressure supply line, an outlet end for distributing a flow of liquid with the inlet orifice and tubular body collapsible in response to pressure to maintain a generally predetermined uniform flow rate over a predetermined pressure range. The inlet end of the tubular member tapers down to a reduced teardrop inlet orifice with the outlet opening in one embodiment comprising a crescent shaped slit in the wall of the tube.
