Abstract

In a device for cleaning pipelines (1), there is a four-way change-over valve (2) to whose inlet connection (5) a pressure limiting valve (3) is connected. Its valve connector can project as far as the valve openings (11, 12) of the piston (8). The pressure limiting valve (3) relieves pressure towards the outlet connection (6). In this way, pressure surges in the device (1) can be reduced and damage can be avoided. <IMAGE>
