Abstract
A helically shaped dynamic seal ring is provided. The helically shaped dynamic seal ring includes a spirally wound body and a snubbing orifice area formed in the spirally wound body. The spirally wound body is configured to expand in response to contacting a snubbed stroke range of an actuator piston. The spirally wound body is configured to contract in response to distancing from the snubbed stroke range of the actuator piston.
