20100122882 | DRIVEN ACCESSORY WITH LOW-POWER CLUTCH FOR ACTIVATING OR DE-ACTIVATING SAME - A driven accessory having a clutch that permits selective operation of an accessory portion. The clutch employs rotational inertia to control driving engagement of a wrap spring to an interior clutch surface on a drive member and/or driving disengagement of the wrap spring from the interior clutch surface. | 05-20-2010 |
20130008758 | DRIVEN ACCESSORY WITH LOW-POWER CLUTCH FOR ACTIVATING OR DE-ACTIVATING SAME - A driven accessory having a clutch that permits selective operation of an accessory portion. The clutch employs rotational inertia to control driving engagement of a wrap spring to an interior clutch surface on a drive member and/or driving disengagement of the wrap spring from the interior clutch surface. | 01-10-2013 |
20130098730 | CLUTCH FOR SELECTIVELY DRIVING AN ACCESSORY - A clutch assembly having a driver, an output member, a clutch spring, an armature and an actuator. The clutch spring includes a plurality of coils that are configured to be drivingly engaged with the driver. The clutch spring further includes first and second ends. The first end is configured to drivingly engage the output member to facilitate the transmission of rotary power from the driver, through the clutch spring and into the output member. The second end is engaged to the armature. The actuator is selectively operable for rotating the armature relative to the driver in a rotational direction opposite a predetermined rotational direction in which the driver is driven to thereby initiate at least partial disengagement of the coils of the clutch spring from the driver. | 04-25-2013 |
20130313068 | DRIVEN COMPONENT WITH CLUTCH FOR SELECTIVE OPERATION OF COMPONENT - A component, such as an engine accessory for an automotive engine, that has clutch with a helical clutch coil and an axially movable armature. The helical clutch coil is normally engaged so as to transmit rotary power between a driving member and a driven member. The armature can be moved to apply a force to a tang of the helical clutch coil that causes the helical clutch coil to disengage to an extent where full rotary power is not passed through the clutch to drive the component. | 11-28-2013 |
