ABSTRACT:
A control component such as a valve or throttle member for a hydraulic system comprises an outer member, and a body portion disposed in the outer member and having an outside surface co-operable with an inside surface of the outer member, the outer member and body portion being movable relative to each other. The flow duct extending between the inlet and outlet of the component includes at least one flow passage which opens at the outside surface of the body portion, and the mouth opening of the flow passage communicates with a curved duct portion which extends at an inclined angle relative to a radial plane through the body portion. The flow section of the or each duct portion decreases towards the tip thereof, to provide finely adjustable control of the flow of fluid through the component.
