The torque converter lockup clutch (2) is engaged when the supply pressure (p_WD_zu) of the torque converter (1) is lower than a predefined pressure level of the supply pressure (p_WK_zu) of the torque converter lockup clutch. A converter pressure valve (WDV) is provided for controlling the supply pressure (p_WD_zu) of the torque converter (1), and a converter coupling valve (WKV) for controlling the supply pressure (p_WK_zu) of the torque converter lockup clutch, where their valve slides (WDV_S, WKV_S) can be acted upon by at least one pre-control pressure (p_VS) and one system pressure (p_sys). When the torque converter lockup clutch (2) is disengaged, the valve slide (WKV_S) of the converter coupling valve (WKV) is acted upon in such a way on an active surface (15) by the reverse pressure (p_WD_ab) of the torque converter (1), and when the torque converter lockup clutch (2) is engaged, is acted upon in such a way on the active surface (15) by the reverse pressure (p_WK_zu) of the torque converter lockup clutch (2), that at least either the supply pressure (p_WD_zu) of the torque converter (1) or the supply pressure (p_WK_zu) of the torque converter lockup clutch (2) is higher than a predefined pressure level (p—0) over the entire operational area of the torque converter (1).

摘要： A device for operating a starter mechanism actively connected with a hydraulic supply circuit of a transmission unit. The starter mechanism has a piston chamber subject to hydraulic pressure for activating a frictional shift element and a hydraulic chamber subject to hydraulic pressure for the cooling and lubricating an area of the starter mechanism. A hydraulic pressure between a lubrication pressure control port of a second pressure relief valve and the hydraulic chamber and equivalent to a lubrication pressure, is exerted on a second back pressure outlet port of a first relief valve, which acts on a valve slide of the first relief valve in the opposite direction relative to the working pressure exerted on a first back pressure outlet port of the first relief valve so that the pressure feed-back of the hydraulic pressure to the first relief valve occurs additively to the pilot signal characteristic of the first relief valve.

摘要： A hydraulic system of a transmission, especially of an automatic transmission of a motor vehicle, having several pressure circuits which can be loaded with hydraulic fluid from a pressure source and in relation to the supply of different areas of the transmission are differently prioritized. The pressure in the pressure circuits is adjustable according to a system valve and one of the pressure circuits comprises a cooling device for the hydraulic fluid and a lubrication circuit located downstream of the cooling device. Between the cooling device and the lubrication circuit is provided a bypass pipe lockable via a valve unit which can be controlled via the valve unit so that the hydraulic fluid flow rate to be passed via the cooling device can be adjusted without changing the hydraulic fluid flow rate to be fed to the lubrication circuit.
