Abstract
Abstract A hydrodynamic torque converter in which a stator is mounted on a one-way roller clutch or brake operatively connected to a grounded sleeve. The one-way roller clutch has a roller energizer which urges the clutch rollers to a position of incipient wedging engagement between the clutch races responsive to the fluid flow conditions within the hydrodynamic torque converter during the torque multiplying and fluid coupling modes of operation.

Claim 1
Independent Claim
137 words
In a hydraulic torque converter having a bladed pump and a bladed turbine discharging hydraulic fluid into the inlet of the bladed pump through a bladed stator operatively connected to a ground sleeve by a one-way roller clutch for providing torque multiplying and fluid coupling modes of operation, the improvement comprising: a roller energizer for locating the rollers of said roller clutch at a position of incipient wedging engagement with the clutch races responsive to the flow of hydraulic fluid in said hydraulic torque converter during the operation thereof, said roller energizer being mounted in said torque converter for rotation relative to said clutch races and having a plurality of fingers individually engaging said rollers and a plurality of paddles disposed in the hydraulic fluid between the outlet of said stator and the inlet of said pump.
