ABSTRACT:
The present invention relates to a regulating device (1) for control of flow and/or pressure, including a housing (3) enclosing a movable inner member (2) which is provided with a passage corresponding to the housing inlet. The inlet comprises at least two ports (4,5,6,7) which are spaced apart with a circumferentially equal distance, and the passage comprises apertures (8,9,10,11) positioned correspondingly. The inner member (2) 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.
