ENGINE CONTROL VALVE WITH IMPROVED SEALING

摘要

The invention relates to an engine control valve including a body defining an inner duct and comprising a flap (10) mounted such that it can pivot by means of a shaft (12), said flap (10) comprising a first portion (11). The flap can pivot between an open position allowing the passage of fluid into the duct and a closed position in which the flap (10) comes into contact with a flat seal (100) of the flap. The outer contour of the seal (100) surrounds the outer contour of the flap (10), said seal (1) comprising an opening (6) and a solid portion (3). The above-mentioned first portion (11) seals the opening (6) in the seal (1) when the flap (10) is Z in a closed position. The seal (100) includes a reinforcement area (101) in the solid portion (3) thereof, such as to prevent the seal (100) from deforming owing to the high pressure and high temperature of the gases in the valve.

主权项

1. An engine control valve having a body that delimits an internal duct and comprising:
a flap mounted in a pivoting manner by way of a pin, said flap comprising a first part and being able to pivot between an open position allowing fluid to pass through the duct and a closed position in which the flap comes into contact with a gasket of the valve, said gasket having an external contour that externally surrounds the external contour of the flap and comprising an opening and a solid portion, said first part closing off the opening in the gasket when the flap is in a closed position, and the gasket having a reinforcing region in its solid portion, so as to prevent said gasket from deforming under the effect of a high pressure and a high temperature of the gases present in said valve.
