Abstract

A pressure relief valve has a body through which is capable of axial flow guidance on at least part of the length, and a valve piston loaded by a spring is inserted in a piston guide, and hermetically enclosed by the piston guide. The piston guide comprises a guidance surface for guiding the fluid onto the reflection surface of the valve piston.
