ABSTRACT:
A hydraulic tilting device for tilting a cab mounted on the chassis of a vehicle between a driving and a tilted position comprises a reservoir for hydraulic fluid, a pump connected to the reservoir, and a double-acting hydraulic tilting cylinder. A lost-motion conduit is provided between ports opening into a push chamber and a pull chamber in the cylinder space of the tilting cylinder when the piston/piston rod assembly is in a lost-motion range defined by the ports. When under the influence of the movements of the piston/piston rod assembly within the lost-motion range, the pull connection of the tilting cylinder causes suction of hydraulic fluid out of the reservoir, forcing hydraulic fluid from the reservoir into the pull chamber, and moving hydraulic fluid from the pull chamber to the reservoir through the lost-motion conduit. Hydraulic fluid therefore circulates when the cab is carrying out spring movements.
