Relief valve

摘要

Technical problem: In fluid-controlled machine assemblies, connecting lines must often be switched within a very short period. This can occur, for example, when assemblies are overloaded or there is a sudden requirement for emergency braking. Existing valves still have relatively high piston masses which reduce the opening time. Solution According to the invention, this problem is solved by virtue of the fact that the guide element 4 of the valve piston 2 is a tubular section with apertures 11, in particular holes, which are exposed by the opening movement of the valve piston and thus open the connection between the space 6 under pressure and the outlet 7. <IMAGE>
