摘要： A power steering system for a motor vehicle includes a rack and pinion assembly in which the teeth of the pinion are engaged with the teeth of the rack. The power steering system further includes magnets (e.g., permanent magnets or electromagnets) connected to the rack, as well as magnets (e.g., permanent magnets or electromagnets) connected to a rack tube. A varying maglev (i.e., magnetic levitation) force obtained by controlling current flowing through at least some of the magnets (e.g., by varying duty cycle of pulse-width-modulation through an electronic control unit) provides steering assistance for the motor vehicle employing the power steering system. A power steering system includes first and second steering elements, magnets connected to the steering elements, and a controller configured to obtain speed information and steering position information and to control the activation of the magnets in response to the speed information and steering position information.

摘要： A valve assembly includes a housing defining first, second, third, and fourth passages. The first passage channels relatively-high pressure fluid and the second passage channels relatively-low pressure fluid into the valve. The third passage connects to the second passage and releases fluid from the valve. The fourth passage connects to the first passage and the second passage and releases fluid from the valve. The valve assembly also includes a first check-valve that permits fluid flow from the second passage to the third passage and a second check-valve that permits fluid flow from the second passage to the fourth passage. The valve assembly additionally includes a nozzle that controls velocity of the relatively-high pressure fluid entering the fourth passage from the first passage. The relatively-low pressure fluid is pulled from the second passage into the fourth passage on the outer periphery of the nozzle by the relatively-high pressure fluid.
