The invention discloses a combined service brake and energy storage brake cylinder which comprises a shell, a parking brake push rod and a brake piston, a service brake cavity, an energy storage brake cavity and a brake parking cavity are formed in the shell, and a breather valve is arranged in the parking brake push rod. The breather valve comprises a valve body, an exhaust valve piston, an actuator element, a loading spring and an adjusting spring, a first cavity, a second cavity and a sealing face are arranged in the valve body, one end of the actuator element is arranged in the second cavity, the other end of the actuator element penetrates out of the valve body and is fixed to the shell, the exhaust valve piston is arranged in the first cavity in a sliding mode, and the loading spring is arranged in the second cavity. The loading spring is connected with the valve body and the exhaust valve piston, so that the exhaust valve piston presses the sealing surface towards one side of the second cavity and separates the first cavity and the second cavity in a one-way mode, and the adjusting spring is connected with the exhaust valve piston and the actuator element. The invention provides a combined service brake and energy storage brake cylinder which can reduce the stroke of an exhaust valve piston in a breather valve.
