ABSTRACT:
In a hydraulic circuit used in an electrically operated vehicle having hydraulically operated steering apparatus and a hydraulically operated working device, such as a lifting fork for example, the same pump means supplies working medium to both the steering apparatus and the working device. Arranged in the system of pipes serving the steering apparatus is a device for detecting the pressure in the pipe system. The device is adapted to co-act with the pump means in such a way that when a low pressure value prevails in the system the pump means is activated and is de-activated when a high pressure prevails in said system. Forming part of the steering apparatus is a control valve which can be adjusted so that when the wheels of the vehicle are set for the latter to be driven in a straight line, the valve assumes a neutral position which prevents the flow of working medium so as to prevent movement of said wheels.
