Abstract
A bead gasket for sealing off an axial joint between a first component and a second component, the bead gasket including a first bead loop surrounds a first inner region in an axial view and includes a bead end face for an axial contact with one of the components; a passage for fluid which is located in the first inner region, wherein the first bead loop is a smallest bead loop surrounding the passage; and a first rigidifying structure which extends from the first bead loop into the first inner region in the axial view in order to rigidify the first bead loop.
Claims20
A rotary pump for applying a pressure liquid to an assembly, the pump comprising:
- (a) a pump housing featuring:
- a circumferential wall, which surrounds a delivery chamber of the pump;
- and a first end-face wall and second end-face wall which axially delineate the delivery chamber on its two end-face sides;
- (b) an inlet for the liquid on a low-pressure side of the pump housing and an outlet through which liquid on a high-pressure side of the pump housing can be delivered out of the delivery chamber;
- (c) a delivery member comprising a rotor, which can be rotationally moved in the delivery chamber, for delivering the liquid from the low-pressure side to the high-pressure side and through an outlet of the pump;
- and
- (d) a metal bead gasket comprising (i) a first bead loop which surrounds a first inner region of the bead gasket, through which the liquid can axially flow, and follows a contour of the outlet in an axial contact on the end-face side with respect to the first bead loop, in order to seal it off, in an axial view onto the bead gasket, (ii) a second bead loop which surrounds a second inner region located next to the first inner region in the axial view and comprises a bead end face for an axial contact with the first end-face wall, and (iii) a passage for liquid which is located in the second inner region,
- (e) wherein the outlet emerges on an outer end-face side of the first end-face wall which faces away from the delivery chamber, and the bead gasket is held on the pump housing such that it axially faces the outer end-face side of the first end-face wall, to seal off the outlet.
A rotary pump for applying a pressure liquid to an assembly, the pump comprising:
- (a) a pump housing featuring:
- a circumferential wall, which surrounds a delivery chamber of the pump;
- and a first end-face wall and second end-face wall which axially delineate the delivery chamber on its two end-face sides;
- (b) an inlet for the liquid on a low-pressure side of the pump housing and an outlet through which liquid on a high-pressure side of the pump housing can be delivered out of the delivery chamber;
- (c) a delivery member comprising a rotor, which can be rotationally moved in the delivery chamber, for delivering the liquid from the low-pressure side to the high-pressure side and through an outlet of the pump;
- and
- (d) a metal bead gasket comprising a first bead loop which surrounds a first inner region of the bead gasket, through which the liquid can axially flow, and follows a contour of the outlet in an axial contact on the end-face side with respect to the first bead loop, in order to seal it off, in an axial view onto the bead gasket,
- (e) wherein the outlet emerges on an outer end-face side of the first end-face wall which faces away from the delivery chamber, and the bead gasket is held on the pump housing such that it axially faces the outer end-face side of the first end-face wall, to seal off the outlet, and
- (f) wherein the bead gasket comprises
- a passage for liquid which is located in the first inner region,
- wherein the first bead loop is a smallest bead loop surrounding the passage;
- and
- a first rigidifying structure which extends from the first bead loop into the first inner region in the axial view in order to rigidify the first bead loop,
- wherein the first rigidifying structure which seals off the outlet overlaps with the outlet in the axial view, and the first rigidifying structure which seals off the delivery chamber overlaps with the delivery chamber in the axial view, such that the liquid flows onto the first rigidifying structure when the pump is in operation.
