  • Publication number: 20210140524
    Abstract: A hydrokinetic torque-coupling device includes an impeller wheel, a turbine wheel, a stator, a casing, a stationary shaft operatively coupled to the stator so that a driven shaft axially extends through the stationary shaft, a first fluid passage formed axially through the driven shaft, a second fluid passage formed between the stationary shaft and the driven shaft, a third fluid passage formed radially adjacent to the stationary shaft, and a lock-up clutch including a piston housing member non-moveably attached to a center hub of the casing, and a lockup piston mounted to the center hub so as to be axially movable along the center hub. The first fluid passage hydraulically connected to a first hydraulic chamber. The second fluid passage hydraulically connected to a second hydraulic chamber. The third fluid passage hydraulically connected to a torus chamber defined between the impeller shell and the turbine shell.

  • Patent number: 10323714
    Abstract: A damper with an integrated centrifugal pendulum-type vibration absorbing device is equipped with a drive plate for transmitting engine torque to a transmission. The drive plate has a stepped shape toward the annular outer edge. An annular side plate makes sliding contact with the outermost edge of the drive plate. An annular hub clutch is held between the side plate and the inside annular portion of the drive plate. Multiple torsion springs are arranged such that at least one end makes sliding contact with the hub clutch. A back plate grips the sides of the torsion springs, and is connected to the drive plate. Centrifugal pendulum-type vibration absorbing devices are mounted on a disc-shaped and circular back plate. Centrifugal pendulum-type vibration absorbing devices are mounted on the outer circumferential side of the back plate.

  • Patent number: 4578878
    Abstract: A tobacco drying machine of rotary cylindrical type having a steam pipe at the wall thereof and a heated air source at the lower side of a material supply inlet, comprises means for detecting the flow of tobacco raw material at a pretreatment process line of the drying machine; a water spraying nozzle at the raw material supply inlet into which pressurized air is supplied as a carrier; and a control circuit for providing a signal to the water spraying nozzle when a predetermined period of time has passed since said circuit received a signal representative of the passage of the front or rear end of the tobacco raw material through the detector.
