Control valve
First Claim
1. A switch valve with a valve seat and a valve plate that can be moved from a closed position, in which the valve plate is in contact with the valve seat and the switch valve is closed, into a through-flow position, in which the switch valve is open,wherein the valve plate comprisesa valve plate surface with a circumferential surface edge, wherein said valve plate surface is the surface by means of which the valve plate lies on top of the valve seat when the valve is closed, anda perpendicular, which runs vertically to the valve plate surface and through a center of gravity of the valve plate surface, said perpendicular defining a longitudinal axis L, andwherein a brim is arranged at the circumferential surface edge, wherein the brim comprisesa first part which protrudes from the circumferential surface edge in a downward direction from the valve plate surface anda second part comprising a radial section extending in the radial direction that extends from the first part, the second part further comprising a brim edge extending in the axial direction from the radial section relative to the longitudinal axis L, wherein the radial section has a larger proportion extending in the radial direction than the brim edge extending in the axial direction, the entire radial section being larger than the valve seat diameter.

Abstract
The invention relates to a control valve having a valve seat and a valve disk (1), which can be moved from a closed position, in which the valve disk (1) rests on the valve seat and the relief valve is closed, into a through-flow position, in which the relief valve is open, wherein the valve disk (1) comprises a valve disk surface (2) having a peripheral surface rim (4) and a normal which is perpendicular to the valve disk surface (2), runs through the center of gravity of the latter and defines a longitudinal axis L. A brim is arranged on the surface rim (4), wherein said brim has a first part (6) which projects beyond the valve disk surface (2) in the axial direction with respect to the longitudinal axis L and has a second part (8) which adjoins the first part (6) and comprises a section that is radial with respect to the longitudinal axis L.

4. A switch valve with a valve seat and a valve plate that can be moved from a closed position, in which the valve plate is in contact with the valve seat and the switch valve is closed, into a through-flow position, in which the switch valve is open,
wherein the valve plate comprises a valve plate surface with a circumferential surface edge, wherein said valve plate surface is the surface by means of which the valve plate lies on top of the valve seat when the valve is closed, and a perpendicular, which runs vertically to the valve plate surface and through a centre of gravity of the valve plate surface, said perpendicular defining a longitudinal axis L, and wherein a brim is arranged at the circumferential surface edge, wherein the brim comprises a first part which protrudes from the valve plate surface towards the valve seat in an axial direction relative to the longitudinal axis L, and a second part that extends from the first part, the second part comprising a radial section relative to the longitudinal axis L, wherein the first part of the brim has at least one gap, and wherein the second part of the brim has a cross section in the shape of a wing panel with respect to a radial section relative to the longitudinal axis L, wherein said shape of a wing panel is a shape sufficient to create a vacuum above said second part of the brim.
