Rotary shock absorber for railway applications
ITT Enidine Inc.

The unique RSA is a vane type shock absorber. The fluid-filled opposing chambers are interconnected through a metering valve. Rotational force applied to the end of the wingshaft displaces the fluid from the high-pressure chamber to the opposing low-pressure chamber. This causes a resistance to relative motion and damping of the input force. The amount of damping torque is governed by angular velocity of the load applied to the shock absorber and by the valving settings.

- Rebuildable Design allows for factory-direct reconditioning extending service life

- A Variety of Installation Arrangements solve difficult application problems
- Spring-Loaded Dynamic Shaft Seal prevents external leakage and provides continuous selfadjustment for service wear
- External Access to Fluid Reservepermits periodic check of fluid level
- Resistant to Deterioration caused by water, dirt, or corrosive action increasing dependability of operation
- Automatic "High Shock" Relief Valves protect components from damage due to instantaneous
- shock loads and limit torque developed in operation
- Uniform Damping Characteristics over wide temperature ranges are achieved with an
- automatic temperature-compensating valve
- Factory-Adjustable Valving allows changes in damping resistance to meet application
- requirements or to compensate for wear
- Completely Self-Contained Design
