Question

in a hmu steering system, what is used to dampen the shock on the steering cylinders?

1. rotary spool
2. crossover relief and makeup valves
3. suspension cylinders
4. stator

Explanation:

In an HMU (Hydraulic Modular Unit) steering system, crossover relief and makeup valves are used to dampen shocks on steering cylinders. A rotary spool is part of valve operation, suspension cylinders relate to suspension, and a stator is part of motors/generators, not shock damping for steering cylinders.

Answer:

1. Crossover relief and makeup valves
