A hydraulic system for a utility vehicle supplies primary and auxiliary hydraulic actuators with hydraulic fluid and includes a pump, the pressure of which is controlled with respect to the load pressure of the primary and auxiliary hydraulic actuators. The pressure of the hydraulic fluid from the pump exceeds the load pressure by a predetermined control pressure differential. Valves arc provided for producing two control pressure differentials of different values. When the prevailing load pressure of the auxiliary hydraulic actuator and a highest load pressure of the primary hydraulic actuator is less than the sum of the load pressure of the auxiliary hydraulic actuator and the control pressure differential of the auxiliary hydraulic actuator minus the control pressure differential of the primary hydraulic actuator, the control pressure differential is increased with respect to die control pressure differential in cases where the load pressure of the auxiliary hydraulic actuator does not prevail.

Hydraulic system for utility vehicles

A detachable front-loader comprising a loader assembly consisting of two arms (,) joined by one or more transverse members (,) as shown in FIG.,Each arm (,) is provided with a supporting device comprising a pivotable support foot (,) and a telescopic strut (,). Each support device is movable between a non-operational position wherein the support foot (,) rests against a respective arm (,), and an operational position. The foot (,) is retained in the operational position by locking the telescopic strut (,) in an extended state. Opposing ends (,) of the strut are provided with screw threads (,) which are connected to threaded members (,) pivotally located on the foot (,) and the arm (,).
