    Abstract: A brake system includes a tandem power transmission unit selectively driven by a first electric motor to provide pressurized hydraulic fluid to primary and secondary output lines. A plurality of iso/dump control valve arrangements is provided, with each being associated with a selected wheel brake and selectively provides slip control to the selected wheel brake. A first traction control iso valve is hydraulically interposed between the tandem power transmission unit and at least a selected iso/dump control valve arrangement via the primary output line. A second traction control iso valve is hydraulically interposed between the tandem power transmission unit and at least an other iso/dump control valve arrangement via the secondary output line. A DAP power transmission unit is driven by a second electric motor for selectively providing pressurized hydraulic fluid to the iso/dump control valve arrangement of at least one associated wheel brake.

    Abstract: A brake system includes a source of pressurized hydraulic fluid, a plurality of wheel brakes, and an iso/dump control valve arrangement associated with at least one wheel brake. A reservoir is connected to the source of pressurized fluid and to the iso/dump control valve arrangement. A fast-replenishing circuit includes a FR iso valve, a venting valve, and a replenishing check valve. The venting and replenishing check valves are interposed between the source of pressurized fluid and the reservoir. The FR iso valve is interposed between the source of pressurized fluid and the iso/dump control valve arrangement. When the source of pressurized fluid reaches a predetermined stroke position, the FR iso valve is energized to restrict movement of fluid from at least one iso/dump control valve arrangement to the source of pressurized fluid. The source of pressurized fluid is re-stroked to draw fluid from the reservoir through the replenishing check valve.

    Abstract: A brake system for hydraulically actuating a pair of front wheel brakes and a pair of rear wheel brakes includes a master cylinder fluidly connected to a reservoir and operable to provide a brake signal responsive to actuation of a brake pedal connected thereto. The master cylinder is selectively operable during a manual push-through mode by actuation of the brake pedal to generate brake actuating pressure at an output for hydraulically actuating a selected one of the pair of front and rear wheel brakes. A first power transmission unit is configured for actuating the selected one of the pair of front and rear wheel brakes. A second power transmission unit is configured for actuating the other one of the pair of front and rear wheel brakes. A first electronic control unit is provided for controlling at least one of the first and second power transmission units.

    Abstract: A brake system for actuating front and rear wheel brakes includes a reservoir and a master cylinder operable during a manual push-through mode by actuation of a brake pedal to generate brake actuating pressure at a first output for hydraulically actuating the pair of front wheel brakes. A power transmission unit is configured for selectively providing pressurized hydraulic fluid for actuating the pair of front wheel brakes and the pair of rear wheel brakes during a braking event. First and second two-position three-way valves are provided. Each three-way valve is hydraulically connected with the master cylinder, the power transmission unit, and a selected one of the front wheel brakes. Each of the first and second three-way valves selectively controls hydraulic fluid flow from a chosen one of the master cylinder and the power transmission unit to the selected one of the pair of front wheel brakes.

    Abstract: A fluid separator includes a separator housing defining a longitudinal bore having first and second bore ends. A first fluid passage is in fluid communication with the bore at the first bore end. A second fluid passage is in fluid communication with the bore adjacent the second bore end. A third fluid passage is in fluid communication with a portion of the bore spaced apart from both the first and second bore ends. A free-floating piston is located inside the bore and configured for longitudinal movement with respect to the bore responsive to fluid pressure within the bore. A biasing spring urges the piston toward the second bore end. An end cap is located at the second bore end. The end cap is maintained on the housing via at least two retainers.

    Abstract: An unloading valve is disclosed. A housing defines a primary and secondary pump inlets, and collective and bypass pump outlets. The housing defines a bypass seat. A tappet has first and second tappet ends longitudinally spaced by a tappet body. The tappet is configured for selective longitudinal reciprocal motion between first and second tappet positions. A tappet shoulder is located on an external surface of the tappet body for selective sealing engagement with the bypass seat to allow fluid flow in a bypass direction and resist fluid flow in a collection direction longitudinally opposite the bypass direction. The primary and secondary pump inlets are in fluid communication with the collective pump outlet for flow in the collection direction when the fluid pressure at the primary and secondary pump inlets combined is below a predetermined bypass pressure and the tappet is located in the first tappet position.
