A valve includes a closing element which moves axially in the bushing. The flow entering the valve is directed towards the lower end of a closing element. The outflow is through a port in the wall of bushing. In the lower end of the closing element, there is a groove portion with a straight bottom which deepens towards the flow direction and steers the outlet flow to the port orifice. The groove is formed only in a part of the closing element lower end.
