Dash pot

Dash pot

• A. A device that measures hydraulic pressure.
• B. Sliding piston type accumulator receiving fluid from the arresting gear actuator.
• C. A valve that releases air.
• D. A hydraulic pump device.

Answer: (B)

A dashpot is a hydraulic damper that resists motion by forcing fluid through a restricted path as a piston slides in a cylinder. In arresting gear, it’s implemented as a sliding-piston type accumulator that receives fluid from the arresting gear actuator to absorb energy and provide a controlled deceleration of the gear and aircraft. This damping prevents sudden shocks, reduces peak loads, and smooths the stopping action. It isn’t a device that measures hydraulic pressure, a valve that releases air, or a hydraulic pump.
