Abstract
The oil supply device for a change-under-load transmission having a high-pressure circuit and a low-pressure circuit is designed in such a manner that the high-pressure feed line to the consumer devices of the transmission system incorporates an inlet aperture of small size, the low-pressure feed line is connected between the inlet aperture and the consumer device, and the low-pressure feed line can be cut off from the high-pressure feed line by a one-way valve.
Claims5
Oil supply device for the hydraulic transmission control of an automatic transmission, in particular a change-under-load transmission with demand-orientated oil supply, having a high-pressure circuit comprising high-pressure feed lines to the consumer devices and a low-pressure circuit with low-pressure feed lines to the consumer devices, characterized in that in each case the high-pressure feed lines to the consumer devices of the transmission system incorporate an inlet aperture of small size, the low-pressure feed line is connected between the said inlet aperture and the said consumer device, and the low-pressure feed line can be cut off from the high-pressure feed line by a one-way valve.
