TLDR
The plenum chambers of a hydromechanical torque sensor can be connected to or sealed from each other as a consequence of change in the effective dia. of the pulley to change the ratio of a transmission including a pulley as mentioned in this paper.Abstract:
The hydromechanical torque sensor (14) has cam discs (18,19) with conforming cam faces between which are located spreading elements (20) to tend to move the cam faces apart under high torque to act in use on one half of the expanding pulley via first and second plenum chambers (22,23) connected to a source of hydraulic fluid under pressure. Supply to the chambers is via a throttle.The plenum chambers of the torque sensor can be connected to or sealed from each other as a consequence of change in the effective dia. of the pulley to change the ratio of a transmission including the pulley. The connection between the chambers may be allowed by one-way action of a lip seal (67) or by a valve.read more

Patent
Taper-disc gear
TL;DR: In this article, a taper-disc gear of continuously adjustable step-up, having a fully hydraulic generation of the pressure forces, in which the load-dependent setting of pressure force level takes place via a torque sensor which is seated on one of the gear shafts and via which the power to be transmitted by the gear is introduced into the gear and which forms for the pressure medium a throttle adjustable in a torque-dependent manner.
