Abstract

The invention relates to a sealing device for such throttle valves as comprise a valve housing with a valve seat and a pivotally mounted throttle member which may be pressed against the valve seat to bring about a sealing contact between two interacting sealing surfaces, one on the throttle member and the other in the valve housing and a sealing ring to be mounted in a slot in the valve. The invention is characterized in that the sealing ring (5) has a cross-section of a homogeneous, radially elongated body part (8) of considerable rigidity and resistance to radial deformation, that said body part at its head end (11) has a sealing surface (12) which is one of the two said sealing surfaces, and that from the 'hip' part of the said homogeneous body part extend two essentially radial legs (14, 15), which form flanges of the sealing ring, said flanges being arrnaged to be pressed axially against the walls (18, 19) of said slot.
