Abstract: A filter assembly includes a manifold having a fluid inlet and a fluid outlet, a filter housing having a filter medium provided therein, the filter medium defining an inner filter chamber and defining an outer filter chamber between the filter medium and the filter housing, the filter housing being 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 further includes a valve assembly mounted inside the manifold that includes a valve piston and a valve spring arranged in engagement with the valve piston to bias the valve piston into a first position and to compress, in response to a pressure differential across the valve piston exceeding the spring force, to move the valve piston to a second position.

Abstract: A retention mechanism for releasably securing a receptacle to another component includes a ratchet lever pivotally mounted about a screw, a torsion spring having a first end attached to a first end of the lever and being biased to pivot the lever about the screw axis to a first, locked position. A second end of the lever engages, in use, with teeth provided on the receptacle to secure the receptacle against rotation relative to the other component. The mechanism has a compression spring arranged to bias the lever in an axial position such that, in the first, locked position, the second end of the lever engages the teeth. The first end of the lever is configured to receive pressure from a user against the force of the torsion spring to pivot the lever about the axis such that the second end of the lever disengages from the teeth.
