Abstract
A pump assembly for a vehicle is disclosed. The pump assembly includes a housing defining a cavity extending along a central axis to present a wall disposed radially relative to the central axis and a base transverse to the central axis. The pump assembly also includes a first gear disposed in the cavity. The first gear has a first side and a second side each extending along the central axis. The first side faces the wall and the second side opposes the first side. The first side of the first gear is complementary to the wall. The wall defines a recess adjacent to the cavity and spaced from the base. The recess is in fluid communication with the cavity for providing lubrication between the wall and the first side of the first gear.
