Abstract:
A valve comprising a housing, a rotatable body which can turn inside said housing, and two axially spaced V-shaped sealing rings arranged in the housing and resting sealingly against an outer surface of the rotatable body, wherein at least one V-shaped sealing ring includes a junction region which faces a longitudinal axis of the valve and a sealing lip which extends from the junction region at least partially radially outwardly relative to the longitudinal axis of the valve and lies substantially tangential to the outer surface of the rotatable body at a contact surface, the junction region being connected to a base body, whereby an increased pressure causes the tangential contact surface between the sealing lip and the rotatable body to be displaced radially inwardly toward the longitudinal axis of the valve so that the rotatable body is substantially supported by the junction region upon application of an increased pressure.
