Abstract

See full text

An apparatus for controlling a flow of a fluid, such as a drilling fluid or drilling mud, is disclosed. The apparatus may include: a valve member; and a float member mechanically coupled to the valve member and configured to operate on the valve member when fully submerged in a fluid. The coupled float member is configured to increase flow through the valve member as a density of the fluid decreases and to restrict flow through the valve member as the density of the fluid increases.
