Abstract
The device comprises two armatures one of which is for connection to a support and the other is for connection to a suspended element. A block of elastic material is interposed between, and defines with, the two armatures a closed enclosure. A partition wall provided with at least one calibrated orifice is mounted by the periphery thereof on a first of the armatures and divides the enclosure into two chambers. A liquid fills one of the chambers and at least a part of the other chamber. The partition wall has a part which is movable with respect to the first armature in a direction perpendicular to the mean plane of the partition wall. The first armature has a stop for limiting the extent of the movement of the partition wall.
Claims17
A damper device, in particular for the suspension of an engine in a vehicle, said device comprising in combination a first armature and a second armature, one of which armatures is for connection to a support element and the other of which armatures is for connection to a suspended element or sub-assembly, a block of an elastic material interposed between the two armatures and defining therewith a closed enclosure, partition wall means having a mean plane and a peripheral portion and defining at least one calibrated orifice and mounted by the peripheral portion on the first armature and dividing said enclosure into two chambers, a liquid filling a first of said two chambers and at least a part of a second of said two chambers, the partition wall means being independent of said second armature and having a part which is movable with respect to said first armature in a direction perpendicular to the mean plane of th partition wall, the first armature comprising means for limiting the extent of said movement to a value less than substantially 0.5 mm.
A damper device, in particular for the suspension of an engine in a vehicle, said device comprising in combination a first armature and a second armature, one of which armatures is for connection to a support element and the other of which armatures is for connection to a suspended element or sub-assembly, a block of an elastic material interposed between the two armatures and defining therewith a closed enclosure, partition wall means comprising a rigid plate which has a mean plane and a peripheral portion and defines at least one calibrated orifice, means connected to said first armature and defining a cavity which receives the peripheral portion of the rigid plate with an axial and radial clearance, the plate dividing said enclosure into two chambers, a liquid filling a first of said two chambers and at least a part of a second of said two chambers, the plate being movable with respect to said first armature in a direction perpendicular to said mean plane of the plate, said cavity limiting the extent of said movement.
