ABSTRACT:
In a flow divider valve for pressure feed to a hydraulic circuit for auxiliary power steering and to a hydraulic circuit for a power take-off the interior of a hollow regulator piston receives pressure feed for distribution to the hydraulic circuits. For one such circuit, preferably the power take-off, flow passes via multiple bores and coacting flow control grooves of the regulator piston and a housing in which it reciprocates. Accordingly, a desired flow quantity and pressure advantages are achieved, in comparison with use of a single flow control bore which would require a larger piston traverse causing delays in pressure build-up as well as oscillations and strong flow pulses and energy loss.
