Twin-Tube Dampers for Vertical and Horizontal Application Twin-Tube Principle Vertical damper The function of the twin-tube principle ZF supplies twin-tube dampers in Twin-tube dampers for horizontal installation have a two different sizes, depending on specially designed bottom valve. It reliably prevents the load profile. Their standardized air from entering into the operating chamber even in modular design makes production this installation position, and therefore ensures that cost-efficient. An integrated lift stop the damper always functions safely. is optionally available: This device When...

Twin-Tube Principle Yaw dampers minimize the sine mo- rements, we supply yaw dampers in a wide range of tion effects of the bogie. Specifically technical specifications: based on the twin-tube or rail vehicles with medium and high recirculating principle, as well as a version equipped speeds can be thereby securely kept In contrast to the twin-tube damper for vertical and horizontal installation, in the yaw damper there are additional sealing elements integrated in the rod guide of the piston specifically for small amplitudes (< ± 2 mm). There is also an oil-tight venting valve integrated in...
