Abstract: A filter assembly comprises a filter element, and a mount having at least one port. Each of the filter element and mount has inter-engaging connection formations, where the filter element and mount can be detachably connected to one another. The mount defines a flow path between the port and filter element when the element is connected to the mount and includes a link element which can slide relative to the mount between retracted and deployed positions. The link element has one of a lug and an inclined ramp surface, and the filter element has the other of the lug and ramp surface. The lug and ramp surface form a cam drive where the lug engages the ramp surface as the filter element and mount are assembled, and slide along the surface when the element is rotated to draw the link element out of the mount towards its deployed position.

Abstract: A diffuser for a jet pump of a separator comprises an inlet defining a first flow area; an outlet in fluid communication with the inlet through which fluid exits the diffuser, in which a flow path extends from the inlet to the outlet, and in which the outlet defines a second flow area greater than the first flow area so that a velocity of fluid flowing through the inlet is greater than a velocity of fluid flowing through the outlet; and a communication port extending through a wall of the diffuser with an inlet in communication with an interior of the diffuser and an outlet in communication with an exterior of the diffuser, in which the communication port inlet is between the diffuser inlet and the diffuser outlet, so that contaminants separated from the fluid stream are removed through the communication port.

Abstract: An actuator for a separator for separating contaminants from a fluid stream which includes entrained contaminants. The actuator is arranged to move along an actuator axis to adjust an open cross-sectional area of at least one aperture of the separator, and comprises a flexible diaphragm, and a support assembly for the flexible diaphragm. The support assembly is movable along the actuator axis carrying the flexible diaphragm and has an upper support member mounted on a lower support member. A portion of the flexible diaphragm is located between the upper and lower support members. The lower support member comprises an axially extending support portion coupled to a radially extending support portion. The upper support member comprises a diaphragm anti-inversion feature coupled to a radially extending support portion. The diaphragm anti-inversion feature extends such that it axially overlaps at least part of the axially extending support portion of the lower support member.
