Class Information
Number: 188/297
Name: Brakes > Internal-resistance motion retarder > Having a thrust member with a variable volume chamber (e.g., coaxial or telescoping tubes, compensating reservoir)
Description: Internal resistance motion retarder wherein said first member is moved by a mechanism relative to or within a container for fluid medium; the member together with the container enclosing a space the size of which changes as the member is moved, thus causing fluid contained within the space to be moved relative to both the member and the container.
