Abstract

The valve has a housing (5), in which a valve unit (7) is arranged, where the valve unit including a guiding hole (12) and a guiding unit (6). The valve unit is surrounded by a high-pressure side annular space till the height of the guiding unit. The guiding unit includes a free end (10) which is deformed outwards at a conical projection of the housing during assembling of the valve to obtain a pressure-backed sealing.
