ABSTRACT:
An installation of a pressure control valve provided for cold start in disk-type oil coolers is disclosed. The valve is provided with a valve housing which can be fitted directly into a connection opening between an inlet chamber and a hollow space through which the oil flows. The valve housing is utilized to accommodate a pressure spring which is arranged coaxially and acts upon the valve shutter. The valve housing is provided in the area of the connection opening with at least one desired buckling point such that, when the end of the valve housing impacts on a resistance, the wall of the valve housing will permanently deform to the outside and secure the valve in the connection opening.
