Abstract
The brake cylinder comprises a cylinder body comprising an annular flange and a non-pressure head. The annular flange of the cylinder body defines a plurality of openings. The non-pressure head has an annular flange and a head portion extending from the annular flange. The annular flange of the non-pressure head has a plurality of bosses and a plurality of openings corresponding to and aligned with the plurality of openings in the annular flange of the cylinder body. At least one vent is positioned in one of the plurality of bosses. The cylinder body and the non-pressure head are secured to each other at the respective flanges. The vent is positioned in the boss disposed opposite a mounting portion so that when the brake cylinder is mounted to a railway vehicle, the vent is oriented in a bottom position on the cylinder body with respect to a ground surface.
