Load pressure regulator for exhaust gas turbo charger of combustion engines for automobiles

摘要

The pressure regulator has a box (1) covered by a lid (40) with a first flexible membrane (35) spanned by its outer edge (38)between outer edge (39) of the box and the lid. The flexible membrane, its support part (31) and the connection for the underpressure source are assembled and arranged so that the control rod (18) moves out of the regulator on connecting to the underpressure source. A flexible second membrane (16) on the side of the first membrane facing the control rod and fixed by its outer edge (17) on the box (1) bears by its inner edge (22) against the control rod. A guide device (11) for the control rod is attached to the box at a distance from the second membrane, by its side remote from the first membrane. The outer diameter of the second membrane is smaller than the outer diameter of the first membrane clamped between the box and lid.
