Abstract
In a hydrostatic drive one hydrostatic machine (2 and 4) is adapted for absorbing the sustained braking power or energy. The transmission is furthermore provided with a cooler (9) whose two sides are respectively connected via a threshold pressure valve (7 and 8) with one of two branch ducts (3 and 5) which connect the said hydrostatic machine with a second such machine adapted to act as a drive. The pressure threshold valve is made up of a pressure limiting and check valve.
