The chamber (A) of the overflow outlet control device (A) has an inner circumferential surface which, when viewed in cross-sectional plan view, is generally in the shape of a volute, for directing material entering the chamber (A) via the circular inlet () at the base portion () tangentially outward towards the discharge outlet (A) located in the side wall (). The top wall region () of the interior wall of the chamber (A), a side wall portion () and base portion () together seamlessly form the chamber (A) which is curved in shape internally. When material flows in use between the inlet () and the discharge outlet (A), and passes through the central chamber (A), it encounters no sharp corners or edges, but just smoothly curved or rounded interior wall surfaces. The top wall region () of the chamber (A) also features a protruding flow control formation () which is joined or formed therewith, and which is arranged to extend into the chamber (A), being directed face towards the inlet () such that in use the flow of material into the chamber (A) via the inlet () directly encounters the formation ().

Hydrocyclone overflow outlet control device

A distributor device for use with cyclone separator apparatus, the distributor device comprising, a main body having a distribution chamber therein, the main body including a back wall and a front wall which at least in part enclose the distribution chamber, the main body including a peripheral region between the front and back walls, the device comprising a plurality of delivery outlets arranged in spaced apart relation around the peripheral region the front wall having an inner face and a back wall having an inner face, the device further including a feed inlet to the distribution chamber in the front wall having a main axis extending in a direction between the front and back walls; the back wall having an inner face which includes main face section and a protrusion which extends from the main face section towards the inner face of the front wall.

Distributor device for cyclone separator apparatus

A hydraulically powered rotary actuator is described including: a hydraulic linear actuator which is moveable in both directions between a retracted position and an extended position; a clutch device which is operable between an engaged condition and a disengaged condition; and a rotary output member; wherein the linear actuator is coupled to the rotary output member by way of the clutch.

Hydraulically powered rotary actuator

A hydrocyclone () is disclosed which includes an internal conical separation chamber () which extends axially from a first end to a second end of relatively smaller cross-sectional area than the first end. The separation chamber () includes at least one gas inlet device () which comprises a plurality of openings in the form of a series of elongate slits () arranged in a spaced-apart relationship from one another around an interior circumferential wall () of the gas discharge chamber (). In use the slits () are arranged for admission of gas into the separation chamber () at a region located between the first and second ends.
