摘要: A coolant system for machine tools, includes a pump (12) for the coolant, at least one consumer (10), a pressure sensor (24) for detecting an actual pressure (Pi) in the coolant system, a feedback control device (22) acting upon the pump (12) for regulating the pressure in the coolant system to a target pressure (Ps), and a limiting valve (26) for limiting the pressure of the coolant supplied to the consumer, wherein in that the opening pressure (Plim) of the limiting valve (26) is variable and the feedback control device (22) is adapted to adjust the opening pressure in accordance with the target pressure (Ps) such that it is always a certain amount larger than the target pressure.
