ABSTRACT:
A hydraulic torque converter with a toroidal space bounded by a pump member, a turbine member and a free-wheeling stator has an inlet channel for fresh transmission fluid (oil) which opens into the pump torus at a location spaced from the pump member, preferably via the stator, whereby the relatively cool volume of newly admitted fluid mingles with the fluid already present instead of being immediately centrifugated toward the peripheries of the pump and turbine members from which it would quickly return to the sump. The inlet channel may include one or more radial passages in a spacer ring separating the stationary races of the journal bearings by which the pump member and the stator are supported on a trunnion rigid with the converter housing.
