To protect hydraulic assemblies, in particular to protect hydraulic brace systems, pressure relief valves 1 are used, the closing part 10 of which is formed by a piston 15 , which is connected to the connection 4 , and the valve spring retainer 12 , which comprises said piston, is arranged displaceably thereon and accordingly has a cylindrical design. Between the connection 4 , which is equipped with a blind hole 5 and radial bores 6, 7 , and the displaceable closing part 10 and/or the correspondingly shaped valve spring retainer 12 a damping chamber 20 is formed, which is directly connected to the blind hole 5 and hence to the system pressure.
