Abstract
Abstract A centrifugal separator for separating say, oil from water, for example, in a cooling water system for a machine, has a separating chamber divided into two regions by a transverse plate which serves to collect the lighter fluid on one side and to allow the heavier fluid to flow to the other side around its edge. There may be a separate fluid for spinning the chamber and one of the fluids may also leave the chamber tangentially to help spin it. There may be a conical surface enabling the lighter fluid to run downwardly and inwardly to its outlet to assist separation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
78 words
A centrifugal separator of lighter and heavier fluids comprising a hollow rotor defining a separation chamber, a collector plate in the chamber having inner and outer edges extending transversely in relation to the axis of rotation for collection of one of the fluids, a central post in the chamber which converges downwardly and inwardly to the inner edge of the collector plate, and outlets for the respective fluids respectively adjacent the inner and outer edges of the plate.
Claim 2
Dependent Claim
78 words
A centrifugal separator of lighter and heavier fluids comprising a hollow rotor defining a separation chamber, a collector plate in the chamber having inner and outer edges extending transversely in relation to the axis of rotation for collection of one of the fluids, a central post in the chamber which converges downwardly and inwardly to the inner edge of the collector plate, and outlets for the respective fluids respectively adjacent the inner and outer edges of the plate.
Claim 3
Dependent Claim
30 words
A separator as claimed in claim 1 in which the outlet for one of the separated fluids from the separation chamber extends generally tangentially to assist rotation of the rotor.
Claim 4
Dependent Claim
17 words
A separator as claimed in claim 2 including a baffle protecting the tangential outlet from solid particles.
Claim 5
Dependent Claim
55 words
A separator as claimed in claim 1 in which there are areas on either side of the plate respectively for the separated fluids, including a movable valve member, and a valve passage in the member which is in communication with one or other of the said areas in two different positions of the valve member.
Claim 6
Dependent Claim
42 words
A separator as claimed in claim 4 in which the valve member is biased towards one position but can move against the bias into the other position in response to a change in the pressure of the incoming fluid to be separated.
