Abstract

Switching device for a cooler (21) for brake fluid or the hydraulic oil for a power-assisted steering system, in which there is provided, upstream of the cooler (21) as viewed in the flow direction, a temperature-controlled valve (19) which can assume three positions depending on the fluid temperature at its input side in a manner such that, during a cold start, all the fluid is fed past the cooler and at working temperature all the fluid is fed through the cooler, whereas, after the start, when the operating temperature has not yet been reached, some of the fluid is fed past the cooler and the remainder of the fluid is fed through the cooler.
