Class Information
Number: 188/319.1
Name: Brakes > Internal-resistance motion retarder > Having a thrust member with a variable volume chamber (e.g., coaxial or telescoping tubes, compensating reservoir) > Fluid through or around piston within chamber > Via fixed or variable orifice in piston > Having an orifice adjustment for both jounce or bound (compression) and rebound
Description: Reciprocating piston with fluid flow through an orifice in which the flow restrictor regulates in one direction (i.e., the compression stroke) and in the other direction (i.e., expansion stroke).
