Abstract
A braking power converter for trucks, busses, trailers, semitrailers and cars as a long-term brake, with oil as the working fluid and an oil cooler, wherein one or more high-pressure reciprocating pumps, which can control the transporting capacity up to zero transport, are driven continuously by the vehicle proportionately to the travelling speed, and an oil flow is compressed to a high pressure of roughly 300 to 900 bar during the braking operation, subsequently relieved of pressure and thereby heated up, after which the heated oil flow is recooled in the oil cooler.
