Class Information
Number: 188/293
Name: Brakes > Internal-resistance motion retarder > Using a rotary-type fluid damper > Driving relatively moving element which causes flow of brake fluid
Description: Device wherein a connection between said first member and said mechanism converts turning of the mechanism about its axis into reciprocation of the member perpendicular to said axis; said reciprocation resulting in circulation of fluid medium in which the member reciprocates.
