A particle separator, comprising: a vessel, which is receptive of a fluid flow at an inlet and configured to output the fluid flow at first and second outlets, the vessel including a curved, inwardly facing surface; and a scupper disposed within the vessel; characterized in that: the scupper includes a first portion and a second portion; the first portion of the scupper is connected to the curved, inwardly facing surface of the vessel at a point proximate to the first outlet on an opposite side of the first outlet to the inlet, and wherein the first portion tapers away from the curved inwardly facing surface and leads to the second portion which is attached to a distal end of the first portion, the second portion disposed to cross over the first outlet and extend towards, but stop short of the inlet to define: a first flowpath along which the received fluid flow is directed to flow toward the first outlet between the curved, inwardly facing surface and a first side of the scupper, and a second flowpath along which the received fluid flow is directed to flow toward the second outlet along a second side of the scupper, which is opposite the first side; the second portion defining vents permitting fluid communication between the first flowpath and the second flowpath, such that fluid entering the inlet encounters the second portion and is directed along the first or the second flowpath due to gravitational forces; and in that: the vessel is substantially cylindrical in shape; and the scupper extends along an entire axial length of the vessel. a vessel, which is receptive of a fluid flow at an inlet and configured to output the fluid flow at first and second outlets, the vessel including a curved, inwardly facing surface; and a scupper disposed within the vessel; characterized in that: the scupper includes a first portion and a second portion; the first portion of the scupper is connected to the curved, inwardly facing surface of the vessel at a point proximate to the first outlet on an opposite side of the first outlet to the inlet, and wherein the first portion tapers away from the curved inwardly facing surface and leads to the second portion which is attached to a distal end of the first portion, the second portion disposed to cross over the first outlet and extend towards, but stop short of the inlet to define: a first flowpath along which the received fluid flow is directed to flow toward the first outlet between the curved, inwardly facing surface and a first side of the scupper, and a second flowpath along which the received fluid flow is directed to flow toward the second outlet along a second side of the scupper, which is opposite the first side; the second portion defining vents permitting fluid communication between the first flowpath and the second flowpath, such that fluid entering the inlet encounters the second portion and is directed along the first or the second flowpath due to gravitational forces; and in that: the vessel is substantially cylindrical in shape; and the scupper extends along an entire axial length of the vessel. the scupper includes a first portion and a second portion; the first portion of the scupper is connected to the curved, inwardly facing surface of the vessel at a point proximate to the first outlet on an opposite side of the first outlet to the inlet, and wherein the first portion tapers away from the curved inwardly facing surface and leads to the second portion which is attached to a distal end of the first portion, the second portion disposed to cross over the first outlet and extend towards, but stop short of the inlet to define: a first flowpath along which the received fluid flow is directed to flow toward the first outlet between the curved, inwardly facing surface and a first side of the scupper, and a second flowpath along which the received fluid flow is directed to flow toward the second outlet along a second side of the scupper, which is opposite the first side; a first flowpath along which the received fluid flow is directed to flow toward the first outlet between the curved, inwardly facing surface and a first side of the scupper, and a second flowpath along which the received fluid flow is directed to flow toward the second outlet along a second side of the scupper, which is opposite the first side; the second portion defining vents permitting fluid communication between the first flowpath and the second flowpath, such that fluid entering the inlet encounters the second portion and is directed along the first or the second flowpath due to gravitational forces; and in that: the vessel is substantially cylindrical in shape; and the scupper extends along an entire axial length of the vessel. the vessel is substantially cylindrical in shape; and the scupper extends along an entire axial length of the vessel.
