DEFINITION

Classification: 192/85

(under subclass 82) Devices in which the action of fluid under pressure is used to operate the clutch.

SEE OR SEARCH THIS CLASS, SUBCLASS:

3.29+, and 3.33, for a fluid-pressure operator to engage or actuate a clutch that is combined with a vortex-flow drive.

SEE OR SEARCH CLASS

92, Expansible Chamber Devices, appropriate subclasses for an expansible chamber device, per se, even though disclosed as a means to operate a clutch.

303, Fluid-Pressure and Analogous Brake Systems, appropriate subclasses for systems of distribution of fluid to motors of more general application.
