Abstract

See full text

A hydrostatic variable displacement pump (2) has a displacement volume set by an electro-hydraulic control device (10) provided with a safety function. In a fault scenario, the variable displacement pump (2) is set to a neutral position. The electro-hydraulic control device (10) has a single electro-hydraulic setpoint encoder (30) to specify the setpoint of the displacement volume of the variable displacement pump (2) and an electrically actuatable valve device (35) connected in series downstream of the setpoint encoder (30), by which the direction of displacement of the variable displacement pump (2) is controlled and which is provided with the safety function.
