ABSTRACT:
The fluid-operated brake actuating mechanism comprises a casing having a partition wall to divide the casing into upper and lower coaxial chambers. First and second fluid-tight diaphragms are mounted in the upper and lower chambers, respectively. First and second ports enable injection of a pressurized fluid in the cavities delimited in the upper chamber between the first diaphragm and the partition wall and in the lower chamber between the second diaphragm and the partition wall. A coaxial power spring is mounted into an enclosure formed in the upper chamber at the upper end of the casing for limiting axial extension of the power spring upon opening of the casing to access the upper chamber. The upper chamber can therefore be accessed easily and safely upon maintenance of the brake actuating mechanism. Of course, respective axially slidable members transfer axial forces (a) from the power spring to the first diaphragm or from the first diaphragm to the power spring, (b) from either one of the diaphragms to the other diaphragm, and (c) from the second diaphragm to the brake in view of actuating this brake.
