Abstract
The present invention relates to a regulating device () for control of flow and/or pressure, including a housing () enclosing a movable inner member () which is provided with a passage corresponding to the housing inlet. The inlet comprises at least two ports () which are spaced apart with a circumferentially equal distance, and the passage comprises apertures () positioned correspondingly. The inner member () is fitted with radial play inside the housing so that in operation a leakage of the liquid to be regulated will enter between the inner member and the housing so that these elements are in a floating relationship, whereby the inner member is relieved from radial forces in operation. The invention also concerns a dynamometer testing device.
