A check-valve (1) including a housing (2, 3) having an inlet (5), an outlet (6), a fluid flow path between the inlet (5) and the outlet (6) and a valve seat (7) in the fluid path, the valve seat (7) having a valve seat axis (8), a valve element (9), a valve element support (12) arranged in the housing (2, 3) and supporting the valve element (9), is described, wherein the section (19) of the fluid flow path is formed between the housing (2, 3) and the valve element support (12) and the valve element (9) is moveable between a position in which it rests against the valve seat (7) and a position in which contacts against the valve element support (12). Such a check-valve should have a simple construction keeping low noise and wear. To this end, the valve element support (12) includes at least one recess (12) having an open side to the section (19) of the fluid flow path and connecting the section (19) of the fluid flow path to a space between the valve element (9) and the valve element support (12.)
A check-valve comprising a housing having an inlet, an outlet, a fluid flow path between the inlet and the outlet and a valve seat in the fluid flow path, the valve seat having a valve seat axis, a valve element, a valve element support arranged in the housing and supporting the valve element, wherein a section of the fluid flow path is formed between the housing and the valve element support and the valve element is movable between a position in which it rests against the valve seat and a position in which it contacts the valve element support, wherein the valve element support comprises at least one recess having an open side to the section of the fluid flow path and connecting the section of the fluid flow path to a space between the valve element and the valve element support.
