Power steering pump apparatus

摘要

An improved power steering pump integrates into a single assembly the pump (10), the reservoir (20) and a filtration system. The reservoir (20) includes upper and lower chambers (26, 24) and a primary filter (40) therebetween. The filtration system may also include a secondary filter (42) for providing filtration of fluid added through a filler device (31). The reservoir (20) may also include a bypass chamber (30) and a fluid bypass (66) with a bypass valve (68) for permitting fluid to bypass the primary filter (40) in the event the fluid exceeds a predetermined viscosity.
