HYDRAULIC TILTING SYSTEM COMPRISING A PUMP THAT SUPPORTS SINKING

The present invention relates to a hydraulic system for tilting at least one tipper body located on a tipper vehicle, comprising at least one hydraulic cylinder (24) as a tilting drive unit for the tipper body, at least one tilting valve (18) for controlling at least a lifting operation and a holding operation of the hydraulic cylinder, at least one hydraulic reservoir (12) and at least one hydraulic source (16), as well as at least one valve (110) which is in hydraulic communication at least with the hydraulic cylinder (24) and the hydraulic reservoir (12), via which hydraulic fluid can be discharged from the hydraulic cylinder (24) in a discharge volumetric flow rate bypassing the tilting valve (18) to the hydraulic reservoir (12) for a lowering operation of the hydraulic cylinder. According to the invention, a suction pump (200) is provided which supports the discharge of the hydraulic fluid in the discharge volumetric flow rate bypassing the tilting valve (18), via which at least a partial volumetric flow rate of the discharge volumetric flow rate can be supplied to the hydraulic reservoir (12).
