Abstract
A hydraulically operated automatic transmission assembly wherein a group of dynamic fluid consumers including a continuously variable transmission or a planetary change-speed transmission and a clutch is regulated by a unit which receives pressurized hydraulic fluid from a pump. The pump further serves to supply fluid to several static consumers, such as a torque converter and one or more cooling and/or lubricating units. The fluid which is supplied to the static consumers is influenced by a hydraulic resistor, such as a diaphragm or a throttle, and the quantity of such fluid is maintained within an acceptable range irrespective of eventual leakage of fluid which is being conveyed to the dynamic consumers and irrespective of pronounced fluctuations in the quantity of fluid being necessary for certain modes of operation of the dynamic consumers.
