A control block comprising a plurality of control block elements in each of which a valve arrangement for controlling an associated hydraulic consumer is provided, characterized by an oil channel through which oil flows for controlling the temperature of at least one control block element independently of the control of the valve arrangement, wherein a nozzle is arranged in the oil channel, and a constant pressure difference is produced across the nozzle by a pressure reducing valve provided between a feed line and a control oil supply passage such that a constant volume flow of hot oil flows through the nozzle,
- wherein the nozzle is arranged in a terminal element of the control block including the pressure reducing valve and a pressure limiting valve for control oil supply.
