DEFINITION

Classification: 60/341

(under subclass 330) Apparatus having guide vane means, other than the impeller or turbine vane means, located in the circulatory flow path of the fluid to give a certain direction of flow to said fluid, being axially rotatable with and independently of the impeller and or turbine, and having brake or clutch means whereby said guide vane means may be held against relative rotation with respect to the turbine, impeller or a stationery member.

(1) Note. The brake or clutch found in this subclass may be of the type which are found, per se, in Class 188, Brakes, and in Class 192, Clutches and Power-Stop Control. For the line between this subclass and Classes 188 and 192 see the notes to subclass 330 above.

333, for hydrokinetic units having means to brake or retard rotation of one of the vane means located in the motive fluid flow path whereby the direction of rotation of the turbine means may be reversed.
