Abstract (en)
The system has consumers (2-4), a hydraulic pump (1), and a proportional pressure limiting valve for limiting maximum pressure and connected with the hydraulic pump. The pressure limiting valve is pilot-controlled for switching a bypass, where the pilot control of the pressure limiting valve provides a proportional control of the system pressure to be limited. The pilot control of the pressure limiting valve is effected electrically, electro-hydraulically or electrically and electro-hydraulically, and acts against spring return force and/or system pressure.
