ABSTRACT:
A flow valve mechanism comprising a rotating shaft with a valve body mounted on the shaft for rotation therewith and a valve member mounted for radial movement with respect to said body and said shaft. The valve member has a weighted head and a pressure differential head mounted in a fluid cavity. The pressure differential head divides the cavity into a pair of chambers and an orifice is provided in the pressure differential head communicating with said chambers. A fluid inlet supplies fluid under pressure to one of said chambers, and a fluid outlet is connected to said other chamber whereby the flow of fluid through said orifice and to the outlet will be proportional to the speed of rotation of the shaft.
