An improved drip irrigation emitter for use in drip irrigation systems, the drip irrigation emitter including a hollow body with at least one outlet port and an inlet connector for receiving fluid from main supply lines, a collar with a center bore movably retained within the hollow body, a tapered pin fixedly attached to the emitter and projecting into the collar bore to form an orifice defined as the volume space between the boundary of the bore and the pin periphery for permitting fluid flow between the inlet and outlet ports and a spring assembly for transmitting a continuously variable yieldable force on the collar in a direction to close the orifice.
