Abstract: A fuel filter is provided which comprises a manifold, a connector element, a filter bowl, a filter element, an inlet shutoff valve, an outlet shutoff valve, an inlet port, an inlet passage, an outlet port, an outlet passage and a relief valve in which the connector element is fixed to the manifold, and the filter bowl is reversibly fixed to the connector element. The filter bowl is adapted to reversibly receive the filter element and is so configured that when the filter element is located within the filter bowl and the filter bowl attached to the connection element the filter element divides the space defined by the connector element and filter bowl into an inlet filter chamber and an outlet filter chamber. The inlet port mouths through a surface of the manifold, and the inlet port and inlet filter chamber are in fluid communication via the inlet passage.

Abstract: A nozzle housing for a servo valve includes a circumferential wall defining a return passage extending along a longitudinal axis (A) for holding a return nozzle, the return passage having an opening for fluid communication with a spool valve and a return port for fluid communication with atmosphere, a first plate extending across the return passage, the first plate engaged with the circumferential wall and disposed between the opening and the return port, and a second plate extending across the return passage. The second plate engages with the circumferential wall and disposed between the first plate and the return port, the first plate has at least one first aperture, and the second plate has at least one second aperture that is misaligned with the at least one first aperture such that there is no linear axial flow path between the return port and the opening.

Abstract: A filter assembly includes a manifold having a fluid inlet and a fluid outlet and a filter housing having a filter medium provided therein. The filter medium defines an inner filter chamber and defining an outer filter chamber between the filter medium and the filter housing. The filter housing is removably attached to the manifold so as to provide a fluid flow path from the inlet into the inner filter chamber, through the filter medium into the outer chamber and out of the outlet. The filter assembly also includes a valve assembly mounted inside the manifold, and a by-pass channel defined inside the manifold between the fluid inlet and the fluid outlet. The valve assembly comprises a valve spool and a valve spring arranged in engagement with the spool to bias the spool into a first position and to compress, in response to a pressure differential across the valve spool.
