Abstract: A pressure-controlled valve (100) comprising at least one fluid inlet (101) and at least one fluid outlet (102), a pressure responsive valve seat (103), a pressure responsive valve element (104) arranged movably with respect to the pressure responsive valve seat, a diaphragm (105) which controls the position of the pressure responsive valve element with respect to the pressure responsive valve seat, and a biasing element (106) configured to bias the pressure responsive valve element in a direction away from the pressure responsive valve seat.
The pressure responsive valve element is formed with a wall (160) enclosing an internal space (170) and having a valve edge (150) forming the contact to the valve seat, where the valve seat is formed with a shape curving towards the valve edge.
