ABSTRACT:
An encapsulated rubber cushion loaded mostly perpendicularly to its axis, in which two sleeves, one radially inside the other, are bonded together by a resilient body of rubber. The resilient body contains fluid-filled chambers which are connected at least partially by connecting openings. The dividing walls of the resilient body which separate the chambers from one another have from their manufacture a breadth which exceeds their installed breadth. They thus join the ready-to-use encapsulated rubber cushion in a resiliently compressed state.
