    摘要： An anti-lock brake system includes separate hydraulically boosted master cylinders for each wheel brake or set of wheel brakes to be controlled, an operated actuated brake control valve assembly functioning to channel pump generated fluid pressure to the plurality of hydraulic boosters for simultaneous actuation thereof and including valve means functioning to charge an accumulator with fluid pressure and then discharge the accumulator pressure for booster actuation in the event of a loss of pump generated pressure, a fail safe anti-lock control valve circuit controlling the brakes by releasing and reapplying the hydraulic pressure to the hydraulic boosters in response to the sensed wheel condition, and auxiliary mechanical actuating means for brake actuation subsequent to loss of pump generated fluid pressure and dissipation of the accumulator pressure.

    摘要： A charging valve is disclosed which controls flow of fluid into an accumulator used with a closed center hydraulic brake booster in a vehicle hydraulic system. The charging valve includes a back pressure producing device which creates a fluid pressure level within the charging valve sufficiently high to charge the accumulator while permitting sufficient fluid flow through the charging valve to operate the power steering gear of the vehicle. A shutoff valve is provided in the passage between the inlet of the charging valve and the accumulator. A second valve within the housing maintains the shutoff valve open as long as the fluid pressure level in the accumulator is below a predetermined value, but permits the shutoff valve to close when the fluid pressure level in the accumulator attains the predetermined value. The second valve also operates the back pressure producing device which restricts fluid flow between the inlet and the outlet when the fluid pressure level in the accumulator is below the predetermined value, but permits substantially unrestricted flow between the inlet and outlet of the charging valve when the fluid pressure level in the accumulator attains the predetermined value.

    摘要： A hydraulic brake booster is disclosed which provides a power assist to the vehicle operator during a brake application. Pressurized fluid is normally supplied to the booster from the vehicle''s power steering pump. However, an electric pump is provided to supply fluid to the booster when the power steering pump malfunctions. Flow of fluid between the power steering pump and the booster is controlled by an operator-actuated spool valve which is shiftable from a first position in which the booster chamber is communicated to a fluid reservoir to a second position in which the fluid communication between the chamber and the reservoir is terminated and flow of fluid between the power steering pump and the chamber is initiated. However, when the electric pump is actuated, a stop piston prevents movement of the spool valve. Fluid at a relatively low pressure then circulates through the booster chamber and through internal passages within the spool valve. When the operator applies the brakes of the vehicle while the electric pump is operating, a cap member which is slidably mounted on the spool valve is shifted to a position impeding flow of fluid through the passages within the spool valve, thereby increasing the fluid pressure level within the chamber to apply the brakes of the vehicle.
