  • Device for generating a vacuum in a motor vehicle
    Patent number: 8261716
    Abstract: A device is provided for producing and/or augmenting a partial vacuum in a motor vehicle, in particular for operating a partial vacuum brake servo-unit. The device includes, but is not limited to a throttle unit, which has at least one throttle valve housing and a throttle valve which is arranged so as to be rotatable in an angle range in a throttle channel in the throttle valve housing for controlling a fluid flow in the throttle channel. The device also includes, but is not limited to means for producing and/or augmenting partial vacuum, the means being configured as partial vacuum augmentation means integrated into the throttle valve housing, which partial vacuum augmentation means act according to Bernoulli's principle in the manner of a sucking jet pump to produce an augmented partial vacuum for at least one brake servo-unit.
