Abstract
A coolant and/or lubricant transport device supplies lubricant or circulating cooling water in internal combustion engines. The pump can be driven by an electric motor which can be controlled in dependence upon a control quantity of a continuous controller. The pump can be temporarily stopped or operated to work with an appropriately reduced output to achieve a desired control value.
