ABSTRACT:
A sampling nozzle is disclosed which includes an inlet valve that automatlly adjusts the opening thereof in predetermined inverse porportions to the pressures applied thereto by the fluid and/or other substances being sampled thereby. Whenever a constant pressure suction pump is effectively connected to the outlet thereof, isokinetic sampling is achieved within a system of varying velocities of the aforesaid fluid and/or other substances and, thus, a substantially fixed sampling rate is maintained with respect thereto.
