Abstract

A valve for metering highly pressurized fluid, having an inlet connector that can be placed into a connection socket of a fluid supply line, and a sealing assembly situated on the inlet connector, the sealing assembly having an elastically deformable sealing ring and a support ring made of plastic, which sealing assembly is supported on a radial support shoulder present on the inlet connector and seals against the connection socket. To prevent radial gaps between the support ring on the one hand and the inlet connector and/or the connection socket on the other hand, into which gaps the sealing ring extrudes under high pressure and becomes damaged, the support ring situated between the sealing ring and the support shoulder is made of an elastically deformable plastic material.
