Abstract
A combined power steering hydraulic fluid reservoir and cooling unit (12, 112) includes a housing (14, 114) having a reservoir tank (16, 116) for receiving and collecting hydraulic fluid from a power steering gear (18) and holding the hydraulic fluid in readiness for supply to a hydraulic pump (20). The housing has a heat exchanger (22, 122) with a cooling liquid flow path therethrough in heat transfer relation with the hydraulic fluid, eliminating a hydraulic fluid cooler otherwise connected in series between the power steering gear and the reservoir tank, and eliminating two extra hose connections therefor.
