ABSTRACT:
A hydraulic clutch device which uses a gear pump design as its main element which, in effect, has nowhere to pump.
Its center gear is driven by the input shaft while its housing unit can also rotate and comprises the output shaft.
The center gear meshes with two outer gears and also slides axially so that the amount of its teeth that mesh with the outside gears can be varied. The axial movement of the center gear being achieved with hydraulic pressures and vacuums supplied from within the clutch itself and controlled by a central control slide valve which runs through the center of the input shaft and is controlled by a manually operated lever attached to the supporting framework and coupled to the slide valve with a throwout bearing device.
By moving the center gear over so that it fully meshes with the outer gears the clutch is engaged, and by moving the center gear over the other way so that only a small portion of it meshes with the outside gears the clutch is disengaged.
