Class Information
Number: 188/316
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
Description: Reciprocating piston with fluid flow between chamber compartments wherein fluid moves from one section to another section via (a) an opening in said member extending from one face thereof to an opposite face thereof, or (b) a passageway that exists because said member does not fill the area bounded by the container in which the member moves.
