Abstract
A disconnect clutch comprises a passive centrifugal valve that is utilized to disconnect parasitic loads from an engine during the initial start-up and to automatically connect the parasitic loads once the engine speed is sufficient. The passive centrifugal valve operates dependent on a rotational speed of a flywheel assembly of the clutch and is configured to switch at a threshold rotational speed of the flywheel assembly.
