  • Non-return check valve and check valve apparatus for vacuum system
    Patent number: 12085178
    Abstract: A vacuum system non-return valve includes a baffle for extending across a flow path in the vacuum system and a valve member. The baffle has an aperture, a perimeter of the aperture has a valve seat. The valve member has a curved sealing surface configured to mate with the valve seat. The valve member and aperture are configured such that the valve member obscures the aperture and seals with the valve seat to impede a flow of fluid in a closed position and is displaceable in use to move away from the valve seat and allow a fluid flow in an open position; at least a portion of the surface of the baffle surrounding the aperture slopes towards the inlet end of the valve such that the aperture is smaller at the inlet end than it is at the outlet end.
