Abstract
A viscous clutch includes an input member, an output member, a working chamber, a reservoir to hold a supply of a shear fluid, an outlet, a return bore, an accumulator, and a first wall having an arcuate segment. The reservoir is connected to the working chamber by a fluid circuit, along which the outlet passes the shear fluid from the reservoir to the working chamber and the return bore returns the shear fluid pumped out of the working chamber to the accumulator. The accumulator is arranged in series with the reservoir in the fluid circuit. The first wall is positioned within the reservoir to separate a first portion from a second portion.
