Claim Text:
1. A valve comprising: a housing base having a flange extending axially from the housing base, the flange having a cylindrical outer surface; a valve seat supported by the housing base in a position radially out from the cylindrical outer surface of the flange; an annular slide displaceable substantially axially relative to the housing base between a first operating position where a sealing edge of the annular slide is adjacent to the housing base and seals against the valve seat and a second operating position where the sealing edge is raised from the valve seat to define a gap between the sealing edge and the valve seat to enable flow through the annular slide in fluid flow direction; and at least one flow deflecting element defining a concave groove extending circumferentially around the outer cylindrical surface of the flange and at a position facing radially out toward the valve seat, the flow deflecting element being disposed and configured to deflect a fluid that has flowed between the sealing edge and the valve seat in an inflow direction so that the fluid is deflected back toward the valve seat.
