In shock struts, chevron seals are used to achieve which purpose?

Chevron seals in shock struts are specifically designed to prevent oil from escaping from the system. These seals have a unique design that helps create a strong barrier against fluid loss, ensuring that the hydraulic fluid remains contained within the shock strut. This containment is crucial for maintaining the proper function of the shock strut, as it allows for the necessary hydraulic pressure to be maintained, providing effective damping during operation.

When hydraulic fluid is allowed to escape, the performance and efficiency of the shock strut can be compromised, leading to potential mechanical failure or reduced effectiveness in absorbing shocks. Therefore, chevron seals play a vital role in preserving the integrity and operating capability of the shock strut system by keeping the oil contained.
