Abstract
A fan-coupling device with a unitary magnetic pole is disclosed. The magnetic pole is of a unitary, ring-shaped construction and includes a choke space and a ridge that promote an increased amount of magnetic flux generated by an electromagnet to travel to a magnetic armature on a fluid flow valve, resulting an increase in the amount of magnetic force that acts upon the valve. This is an improvement over the prior art two-piece magnetic pole structure and over a unitary magnetic pole without the choke space and ridge. The magnetic pole also includes apertures in which protrusions on a sound dampening gasket are inserted to reduce the noise resulting from the armature striking the magnetic pole.
