ABSTRACT:
Temperature responsive viscous fan drive having a reduced pump-out time. A pair of diametrically opposed notches opening radially outwardly are provided on the outer peripheral surface of the clutch member of the drive. The notches extend parallel to the axis of rotation of the clutch member between the sides thereof. An impeller element secured to the housing member of the drive is aligned with the notches and located adjacent one side of the clutch member to pump fluid from the operating chamber into the storage chamber. The outer peripheral surface of the clutch member is relatively close to the inner peripheral surface of the housing member.
