    Abstract: An intake manifold (18) for an engine (10) includes a Roots-type supercharger (26) having a torsion damping mechanism (54) for reducing audible gear tooth rattle of timing gears (72,74) which prevent contact of meshed lobes (28c,29a) of the supercharger rotors (28,29). The damping mechanism includes a drive member (90), having an annular band portion (90d) for maintaining the shape of an annular member (98) formed of relatively soft elastomeric material which is fixed for rotation with the drive member via lugs (90e). The member (98) includes three arcuate slots (98d) each defining forward and reverse direction stops (98e,98f) for limiting movement of pins (94) slidably disposed at one end in the slots and fixed at the other end to the gear (74). A torsion spring (96) of low rate resiliently connects the annular member to the pins for reducing the audible gear tooth rattle. Member (98) is snugly constrained against deformation by the annular band (90d) and audible impacts of the stops (98e,98f) is mitigated by the soft material of the annular member (98).

    Abstract: The flywheel elements are connected to one another in drive terms via a spring mounting, an abutment of which is movable relative to the associated flywheel element against the resistance of a second spring mounting and a non-positive coupling arranged parallel to the second spring mounting. Furthermore, a second non-positive coupling, subject to play, is connected between the flywheel elements and is limited resiliently in at least one direction.

    Abstract: A damped vibration system includes a plurality of rotationally inert bodies arranged on a common axis of rotation facing each other with a small gap therebetween. Spring elements are provided between the facing bodies that are displaceable circumferentially with respect to the axis of rotation. Damping elements, preferably in the form of steel balls disposed in radial or circular grooves having sufficient clearance to permit relative angular movement between the facing inert bodies, are provided between the facing bodies. The apparatus is directly connectable to the crank-shaft of the internal combustion engine and also engageable with the drive train of a vehicle. The damped vibration system has a resonant angular frequency preselected to be a certain value below the angular frequency of ignition of the internal combustion engine.

The stopper mechanism includes a first stopper hole, a second stopper hole and a plurality of stop members. The first and second stopper holes are provided on both circumferential sides of each of a plurality of first window holes of the second rotor so as to circumferentially extend therefrom. One or both of the first and second stopper holes communicates at one end thereof with each first window hole and extends at the other end thereof to a position radially outside one of a plurality of second window holes of the second rotor. The stop members are fixed to the first rotor. Each stop member axially penetrates each of the first and second stopper holes and is circumferentially movable within each of the first and second stopper holes.

    Abstract: A spring damper device comprising a directional spring (e.g., coil) having first and second ends, and defining an inner diameter region. A damper (e.g., viscoelastic polymer slug) comprising an element of elasticity configured to be situated within the inner diameter region of the directional spring. In response to a load on the spring damper device, the directional spring operates to compress, and the damper operates to dampen vibration associated with the load. The damper can comprise a viscoelastic damper comprising both an element of viscosity and the element of elasticity. The damper can be substantially coaxially aligned with the directional spring. Spring damper device(s) can be preloaded in a micro adjustment mechanism to account for positional adjustments between two structures (e.g., between a scope and a firearm), such that the spring(s) attenuate a shock impulse event (e.g., when firing), while the damper(s) attenuate vibration (e.g., to prevent damage the scope).

    Abstract: A torsion damper device comprises two coaxial parts, a circumferentially acting resilient element, and a friction device which acts in an axial sense between the two coaxial parts. The friction device includes a friction ring which is in contact with a first friction surface. The friction device is a unitary assembly which comprises at least one element of elastic material. The friction ring is secured over at least one of the faces of the elastic element. This unitary assembly is interposed, so as to be gripped axially, between the first friction surface and a second surface, while an anti-wear element acts between the elastic element and the second surface.

    Abstract: A torsional vibration absorber utilizes a resilient element comprising a coil spring positioned along relative rotational directions between drive and driven plates. The coil spring includes a compressive elastic member loosely positioned within the inner cavity of the coil spring and extending along the axis of the coil spring. Resin sheet elements having a diameter larger than the external diameter of the elastic member are provided as being fixed by bonding to each end of the elastic member. A metallic seat member is positioned at one end of the coil spring so as to provide contact with a corresponding resin member so as to compress the elastic member only in one of the relative rotational directions of the vibration absorber.

    Abstract: A power transmission device disposed in a path from a drive source to a wheel in a vehicle is disclosed. The power transmission device includes an input-side rotary member, an output-side rotary member, and a magnetic damper mechanism. A torque is inputted from the drive source to the input-side rotary member. The output-side rotary member is disposed to be rotatable relative to the input-side rotary member. The magnetic damper mechanism is configured to elastically couple the input-side rotary member and the output-side rotary member in a rotational direction by a magnetic force of attraction. The magnetic damper mechanism has a variable stiffness.
