ABSTRACT:
A low pressure drop adjustable choke has a variably adjustable tapered annular port for metering flow of a fluid. The annular port is defined by a tapered plug extending through a mating, correspondingly tapered seat. The area of the port is selectively varied by axial movement of the plug relative to the seat. The device is mechanically adjustable to a selected flow rate, which may be indicated on a precision indicator.
