Abstract
A power steering pump includes a pump housing (12) and a chambered sheet metal casing (14) around the pump housing. The pump housing and casing cooperate to define a fluid reservoir (22) for the power steering system. The pump housing defines a cylindrical outer surface (30) and the casing defines a circular opening (24) through which the pump housing extends into the casing chamber. An annular groove (32) circumscribes the pump housing cylindrical surface and receives an O-ring seal (34). An annular rim (36) is defined by the casing around the opening into the chamber. The annular rim (36) extends parallel to and closely adjacent the cylindrical outer surface (30) of the pump housing and cooperates with the O-ring (34) to effect a fluid-tight seal between the pump housing and casing. The casing is rotatable relative to the pump housing so that the fluid reservoir is adjustably positionable rotatably relative to the pump housing. The casing defines a radially-extending lip (42) which circumscribes the casing opening (24). Fasteners (46, 72) carried by the pump housing (12) engage the casing lip (42) to hold the casing and pump housing together while allowing adjustable rotational p…
