Abstract: A multi-piston pump includes a housing defining a first plurality of N bores therein, where N is the number of bores in the first plurality. The first plurality of N bores is offset from one another. The housing defines a second plurality of N bores therein. The second plurality of N bores is offset from one another. Each bore of the second plurality of N bores is offset from a corresponding bore of the first plurality of N bores. A substantially straight cylindrical piston is disposed in each of said bores for reciprocal movement along a longitudinal axis therein. The pistons in the first plurality of N bores are operable to induce fluid flow in hydraulic fluid.

Abstract: A brake module provides a first circuit, a second circuit, and a third circuit of pressurized brake fluid. A first set and second set of brake actuators are operated by the application of pressurized brake fluid. A first and second fluid separator unit are integrated between the first and second circuit, and the first and third circuit, respectively, for substantially preventing any intermixing of pressurized brake fluid between the first, second, and third circuits. The first and second fluid separator units include a moveable pressure boundary which enables the second circuit and third circuit of pressurized brake fluid to selectively act upon the first set and second set of brake actuators in response to the first circuit of pressurized brake fluid acting upon the first and second fluid separator units. At least one proportional valve selectively controls the pressurized brake fluid of the first circuit for acting on the first and the second fluid separator units.

Abstract: A hydraulic Control unit of a vehicular brake system includes a housing having a bore formed therein. A normally closed solenoid valve is retained in the bore of the housing. The solenoid valve includes a primary valve and a pilot valve, wherein a cross section of the primary valve is greater that a cross section of the pilot valve. A spring cooperates with the pilot valve so that the pilot valve is open when the primary valve is open.
