Zusammenfassung:	A flow control emitter unit allowing maximum discharge at low pressures for clean out purposes, and restricting flow at higher pressures whereby continual low volume flow is maintained. A pressure responsive member is biased to a position where flow is through the member and directly through outlet ports in the housing carrying the pressure responsive member. In response to a predetermined pressure acting on the pressure responsive member it is moved to a position whereby free flow to the outlet ports is cutoff and flow to the outlet ports is through a variable restriction. The flow through the variable restriction is governed by the pressure acting on the pressure responsive member.
