Abstract:
1. Regulating device for control of liquid flow and/or pressure, including a housing having an axis and a circumferential extension, and being provided with an inlet and an outlet and enclosing an inner member which is arranged to be movable by means of an actuator relative to the housing and provides a passage for regulated liquid flow, characterised in that the inlet comprises at least one group of at least two substantially radial ports which are spaced apart with a circumferentially equal distance, and that the passage comprises a number of radial apertures, each positioned correspondingly with respect to each port, that the inner member is fitted with a minor radial play inside the housing so that in operation a minor leakage of the liquid to be regulated will enter a slit between the inner member and the housing, whereby the inner member is substantially relieved from radial forces in operation.
