Title:
DAMPER DEVICE
Document Type and Number:
Japanese Patent JPS5524299
Kind Code:
A
Abstract:
A damper device comprises a plunger member 106 movable within a cylinder member 100 and sealed thereto by an elastomeric annulus 110 secured to the members so that relative movement of the members is resiliently restrained. The cylinder member 100 defines with the elastomeric annulus and the plunger member a sealed space which contains a hydraulic fluid and which is divided into two variable volume chambers 142 and 144 by a partition 108 past or through which restricted flow of the hydraulic fluid is permitted. In the example of Figure 2 the sealed space is located between the elastomeric annulus 110 and a closed end 102 of the cylinder 100, and the partition 108 is fixed on the plunger member 106. In other examples (Figures 1 and 4) the sealed space is located between the elastomeric annulus 110 and a further similar elastomeric annulus axially spaced therefrom and also secured to the plunger and cylinder members. In this case the partition is fixed to the cylinder member and, if desired, at least one piston having a restricted flow passage therethrough may be secured to the plunger to sub-divide the space into further variable volume chambers.
