ABSTRACT:
A rotary displacement mechanical coupling device having a casing containing a first and second axially aligned chamber, said chambers having a partition therebetween. A hub is rotatably mounted through the partition and extending into both of the first and second chambers. A plurality of outer gear teeth are circumferentially spaced around the outer periphery of the first chamber. A crescent is attached to the hub means in the first chamber and has an outer radius substantially identical with the inner radius of the outer gear teeth. A pinion gear has a plurality of teeth on its periphery and has a radius substantially less than the inner radius of the outer gear teeth, is journaled on the hub so that the pinion gear teeth engage at least a portion of the outer gear teeth. The inner radius of the crescent is adjusted to have substantially the same radius as the radius of the periphery of the teeth around the pinion gear. Fluid communication channels are provided through substantially all of the teeth of the pinion gear. A second fluid communication channel is provided through the journal for the bearing and into the second chamber. A valve is provided in the second fluid communication channel to control the passage of fluids through this channel and into the second chamber.
