Abstract
The invention relates to a hydraulic unit for a hydraulic control device, in particular to a braking pressure control device as used in anti-skid control systems. Such hydraulic units include standardized valve blocks with electromagnetically operable valves. The standardization of the valve blocks implies that the pressure medium connections of the valve blocks have predetermined positions. The invention employs a distributing plate which has a system of channels, in particular in the form of punchings, and which, in a freely selectable manner, connects the valve blocks' connections, the positions of which cannot be changed, with connections of the other components of the control device. The invention provides good preconditions for manufacturing a large number of variants of hydraulic connections, thereby allowing series production of various configurations of braking pressure control devices for anti-skid control systems which are less expensive. Adaptation to client's wishes can be effected more flexibly when using the present invention.
