Abstract
A hydraulic control unit () for an automatic transmission of a motor vehicle includes a volumetric flow rate control valve (). The hydraulic control unit () is configured for delivering hydraulic fluid to an inlet () of the volumetric flow rate control valve (). An outlet () of the volumetric flow rate control valve () is connected to a torque converter torus of the automatic transmission. In addition, the volumetric flow rate control valve () is configured for directing the hydraulic fluid across an orifice (), so that the pressure of the hydraulic fluid is reduced and a constant flow of hydraulic fluid is feedable to a torque converter torus.
