Class Information
Number: 188/276
Name: Brakes > Internal-resistance motion retarder > With means compensating for change in temperature or viscosity
Description: Device wherein motion of a member relative to a fluid medium causes variation in degree of heat or fluidity of the fluid (and thus tends to alter restraining characteristics of the device), provided with means for counteracting effects of such variation, thereby preserving restraining characteristics of the device.
