Abstract

The torque converter of an automatic change speed gear for an automobile has two clutches (4, 6) incorporated in the housing (10) which is driven from the engine shaft (9). When there is no hydraulic pressure within the housing these clutches are engaged by springs (20, 22). When the vehicle is in motion and it is necessary to change gear the lever (38) actuates the slide valve (35) so that oil is admitted to the chambers (24, 28) to disengage the clutches in the correct sequence so that there is no drag on the shaft (13) during the interval in changing from one ratio to another.
