Abstract (en)
[origin: EP2541073A2] The cylinder has a line connection (30) for connecting a control space (25) of a pneumatically steered control valve (21) with a region of an attenuation arrangement under pressurized ventilation. Ventilation pressure in the control space is sealable by a closure assembly (26) during a beginning of attenuation that is characterized by pressure increase in an attenuation chamber (20). The ventilation pressure acts as fixed control pressure on a control piston (23) of the control valve. An opening time point of the control valve is defined for releasing a ventilation path.
