ABSTRACT:
In a working vehicle comprising a hydraulic power steering cylinder (25) and hydraulic lift cylinder (31), a novel hydraulic system is employed which comprises first and second flow control valve means (47, 48; 147, 148; 247, 248; 347, 348), each dividing its inflow into two flows. These valve means are connected in a fashion such that output flow of a single pump (43) driven by engine (10) is first divided into two output flows one of which is then divided by the second valve means. Further, one of the output flows of the second valve means is directed towards the steering cylinder whereas the other of output flows of the both valve means are directed towards the lift cylinder.
The connection is such that, while a predetermined constant flow is secured for the steering cylinder at the normal engine speeds, a flow is necessarily secured for a relatively quick operation of the lift cylinder already at a low engine speed.
