ABSTRACT:
A roll bellows-type pneumatic shock absorber comprises a roll bellows having a wall made of an elastomeric material with embedded stiffening layers. Both end sections of the roll bellows are fastened to a respective fixture. During normal operational conditions the roll bellows forms the rolling crease that changes with the shock absorbing movements. In order to reduce the technical expenditure during the manufacture and mounting of the pneumatic shock absorber and in order to provide a light weight roll bellows, one end section of the roll bellows is embodied as an additionally reinforced roll bellows wall section, which is inherently stable with respect to the inner pressure of the pneumatic shock absorber and the outer loads exerted via the rolling crease. Thus, the roll bellows rolls with its rolling crease over the reinforced roll bellows wall section, i.e., over itself.
