A vane pump has a housing defining a closed conduit fluidly coupling a discharge port and a planar surface, and an inner rotor eccentrically supported within a cam. The rotor has an outer perimeter defined by wall sections separated by axial slots. The rotor defines another closed conduit extending from one of the wall sections to a rotor end face that is configured to overlap with the closed conduit.

Vane oil pump with a relief passage covered by an inner rotor to prevent flow to a discharge port and a rotor passage providing flow to said port

An engine assembly has a damper rotationally coupled to a crankshaft. The damper has first and second spokes connecting a hub to an inertial weight, with the inertial weight circumferentially surrounding and spaced apart from the hub. Each of the spokes has an airfoil section. The first spoke is oriented with a positive angle of attack and the second spoke is oriented with one of a negative angle of attack and a zero angle of attack. A crankshaft damper is provided by a member having first and second spokes extending radially outwardly from a huh to an outer rim supporting an inertial weight. A chord associated with the first spoke is oriented at a first angle of attack relative to a rotational plane of the member. A chord associated with the second spoke is oriented at a second angle of attack relative to the rotational plane.
