DEFINITION

Classification: 475/116

Fluid controlled mechanical clutch or brake:

(under subclass 31) Subject matter wherein a clutch* or brake* operated by fluid pressure is effective to regulate the speed ratio* of the planetary transmission.

SEE OR SEARCH THIS CLASS, SUBCLASS:

209, for an interrelated control between a planetary and nonplanetary transmission.
