发明名称 Flow-control valve
摘要 In a flow-control valve with at least two connecting ports leading into a housing chamber, a hollow control piston (8) which can be adjusted in the housing chamber, has at least one control surface, interacts orifice-like with a lateral connecting port (4, 5) by means of a control edge (14) and adjusts the orifice size during its adjustment, and a baffle body which reaches into the hollow space of the control piston and has facing the flow through the orifice a baffle surface (19) reaching between the orifice and the control surface, to minimise the influence of dynamic flow forces on the characteristic of the valve, the baffle surface (19) is mounted in a floating manner at least in the adjusting direction of the control piston (8), and means (M1, M2) are provided for displacing the baffle surface (19) as a function of the regulating movement of the control piston (8). <IMAGE>
