Abstract

The invention relates to a measurement coupling for fluid systems, for taking working pressures or temperatures of the fluid media, consisting of a coupling bushing which is under duct pressure in the built-in state, and in the bore of which is arranged a spring-loaded and mechanically actuatable check valve, the check valve being constructed as a valve body provided with a cylindrical bore and a closed bottom face, the end of the coupling bushing facing the fluid system being prolonged beyond the valve body. A radial transverse bore or a radial slot is located in the wall of the valve body. In a further embodiment of the invention, the radial transverse bore or the transverse slot is formed in the wall of the guide part of the valve body and a flow slot channel is formed between the valve body and the coupling bushing as far as the radial transverse bore or transverse slot.
