A reservoir assembly for retaining a fluid includes a body having a base and external side walls defining a cavity. A baffle has a top surface spanning the cavity and includes a peripheral wall substantially conforming to the external side walls and extending to the base. A lid is connected to the body. The cavity is divided into a first, second and third compartment by a cooperation between the top surface of the baffle, a plurality of walls of the baffle, the base of the body and the external side walls of the body. The first and second compartments are in fluid communication with each other through the third compartment. An inlet port and an outlet port for allowing fluid to enter and exit the cavity are fluidly connected to the body and are fluidly connected to each other by the first compartment to direct a flow of the fluid.

Reservoir assembly

A hydraulic flow return system of a transmission pump in which primary and bypass flows of hydraulic fluid are returned to primary and bypass flow channels, respectively, of a booster nozzle situated adjacent the rotating group at the inlet of the pump for delivery a boosted flow of high pressure fluid to the pump as a result of the incoming bypass flow being passed through a flow restrictor before being recombined with the primary flow, the system is improved by incorporating a bypass valve which senses the back pressure in the incoming bypass flow and operates to open an auxiliary bypass channel in the event that the back pressure exceeds a predetermined control value in order to divert a fraction of the bypass flow around the flow restrictor for delivery to the pump until such time as the back pressure falls below the control value.

A hydraulic transmission fluid supply system for operating a transmission of a vehicle includes a hydraulic pump having an inlet and an outlet communicating with an inlet of the transmission. A filter assembly includes a filter housing having an inlet communicating with a source of hydraulic fluid and a fluid outlet communicating with the inlet of the pump. A check valve is associated with the filter housing inlet to permit only one-way flow of fluid through the system such that in the event the transmission develops an air leak, the fluid is nonetheless maintained in the system and not permitted to back flow through the system.

A sliding vane pump comprising a rotor housing having a pumping chamber, a rotor in the pumping chamber having a plurality of radially disposed slots, and a plurality of sliding vanes disposed in the slots configured to extend to follow an inner wall of said pumping chamber.

A tuner hose assembly for a motor vehicle power steering system including a flexible hose, a first flexible tuner tube inside the flexible hose having an upstream end connected to a pump, and a second flexible tuner tube inside the flexible hose having a downstream end connected to a power steering gear. A downstream end of the first flexible tuner tube is longitudinally separated from an upstream end of the second flexible tuner tube by a wave interference gap which terminates where an inner wall of the flexible hose is clamped against the upstream end of the second flexible tuner tube. The length of the second flexible tuner tube is selected, i.e. 'tuned', to attenuate higher order pump fluid-borne noise and simulates a rigid metal tube of a prior tuner hose assembly having greater overall length.
