A brake system for a rail vehicle including a brake cylinder having a housing, a port on the housing for receiving fluid pressure signals, a pressure piston carried inside the housing, and a shaft connected to the pressure piston. The pressure piston and the shaft form an actuator to apply and release the brakes of the rail vehicle. A parking brake locking mechanism is connected to the actuator and is responsive to fluid signals from a fluid charged brake pipe to lock and unlock the parking brake locking mechanism. Further included is a manual release device configured to unlock the parking brake locking mechanism from the locked position.

Parking brake system including a brake cylinder

A brake system for a rail vehicle including a brake cylinder having a housing, a port on the housing for receiving fluid pressure signals, a pressure piston carried inside the housing, and a shaft inside the housing. The shaft is connected at one end to the pressure piston and at the other end to a device to apply and release the brakes of the rail vehicle. A parking brake locking mechanism is located inside the housing and includes first and second elements cooperating to lock and unlock the parking brake locking mechanism. Further included is a device for unlocking the parking brake locking mechanism from the locked position.
