A hydraulic reservoir with a baffle is provided to mass produce a reservoir housing by forming a flange at a baffle structure. A hydraulic reservoir with a baffle comprises a reservoir housing(124), a baffle member(62), and a unit for fluid tight seal(70). The reservoir housing defines a fluid chamber(128) for holding hydraulic fluid. The housing further defines an inlet(130) through which hydraulic fluid enters the fluid chamber and an outlet(134) through which hydraulic fluid is discharged from the fluid chamber. The baffle member is disposed within the fluid chamber above the inlet. The baffle member partitions the fluid chamber and separates an upper zone(128a) of the fluid chamber positioned above the baffle member from an inlet zone(128b) of the fluid chamber positioned below the baffle member. The baffle member defines a central opening disposed radially inwardly of the reservoir housing and provides fluid communication between the inlet zone and the upper zone, wherein the baffle member and the reservoir housing define a flow path. Hydraulic fluid introduced into the fluid chamber through the inlet is substantially directed to flow circumferentially along a radially outer section of the inlet zone whereby air entrained in the hydraulic fluid collects in a central portion of the inlet zone proximate the central opening, and is subsequently communicated to the upper zone thereby deaerating the fluid. The unit for fluid tight seal forms a substantially fluid tight seal between the reservoir housing and the baffle member along an outer radial edge of the baffle member. |
