Abstract

The invention relates to a hand pump for actuating a hydraulic, double-action cylinder in order to tilt the cab of a lorry, having a switch-over valve for tilting, tilting back and, optionally, idle position, having two hydraulic connections for the supply line and return line to the hydraulic cylinder in the flow direction of the hydraulic fluid of the actual pump section downstream of the switch-over valve, characterised in that the hand pump is provided with a separate pressure connection which is guided out of the hand pump and is connected between the switch-over valve and the actual pump section, and with a separate suction connection which is connected to the tank or to the line leading to the tank.
