Briefly, according to this invention there is provided a viscous fluid mount for interconnection between a vibrating body and a base. The viscous fluid mount includes a chamber, a high viscosity damping fluid contained within the chamber and a flow resistance device. Input energy from the vibrating body is dissipated by shear friction of the damping fluid moving parallel to the shear surface area of the flow resistance device.

Viscous fluid mount

A slipper bushing assembly including a series of concentric members for permitting controlled sliding movement between a support element and a movable element. The concentric members of the slipper bushing assembly include a rigid one piece inner metal member joined to the support element, a hollow cylindrical elastomeric member, a rigid, one piece hollow outer metal member, a solid slip surface and structure for preventing the inner metal member from disengaging from the outer metal member. The inner metal member has a pair of opposing ends and an outer cylindrical-like surface. The elastomeric member encircles the outer surface of the inner metal member and has a pair of opposing ends, an outer surface and an inner surface. The outer metal member is joined to the movable element and has a pair of opposing ends and an outer cylindrical surface. The slip surface is contiguous to the inner or outer surface of the elastomeric member and coextensive therewith.
