ABSTRACT:
A pneumatic brake cylinder device employs a pair of different sized fluid motors, the pressure chambers of which serve as air storage reservoirs. The cylinder of the larger fluid motor is formed by the main casting and contains a larger piston, while the cylinder of the smaller fluid motor is mounted to the main casting in coaxial relationship with the larger cylinder and contains a smaller piston having an elongated hollow body that is connected at its open end to one side of the larger piston to form a pressure chamber therebetween. The smaller piston fits within the smaller cylinder in spaced-apart relationship therewith to form a pressure chamber delimited by a seal fixed on the main casting for engagement with the piston periphery at any point along its longitudinal axis. The larger piston cooperates with the larger cylinder to form pressure chambers on opposite sides thereof.
The arrangement provides for a design employing fewer seals and a simplified main casting in which all the passages to the respective pressure chambers are contained.
