摘要： A flow control system and a valve for controlling a fluid flow in a flexible conduit. The valve includes a movable member movable to compressingly contact the outer surface of the flexible conduit to adjust the flow cross-sectional area of the flexible conduit. The flow control system includes the flexible conduit, the valve, and a controller. The controller is operatively connected to the movable member for controllably moving the movable member.

摘要： A torque sensing apparatus for use with a brake caliper having opposing brake pads positioned on opposite sides of a rotor. The brake caliper causes the brake pads to apply a braking force against the rotor that generates a braking torque. A torque transfer device is supported by the brake caliper and is in contact with one of the brake pads. The torque transfer device is resiliently movable with respect to the brake caliper in response to the braking torque. A torque sensor is positioned in a sensing relationship relative to the torque transfer device. Thus, the torque sensor provides an output signal related to a change of position of the torque transfer device and the braking torque. The torque sensor includes a magnet mounted on the torque transfer device and a magnet field sensor, for example, a Hall Effect sensor, is mounted on the brake caliper.

摘要： A brake booster provides additional boost capacity without unduly increasing booster size and weight by providing a vacuum pump connected so as to add its additional vacuum capacity to that of the normal vacuum source when activated in response to sensed approaching run-out. The additional vacuum is provided by connecting the vacuum pump in a second conduit between the vacuum source and the booster vacuum chamber in parallel with a first conduit connecting the vacuum source directly with the booster vacuum chamber, with check valve means in the first and second conduits preventing substantial vacuum loss from the vacuum chamber. Approaching run-out is signaled by a sensor responsive to a vacuum level in the working chamber; and control means are responsive to a predetermined low value of the sensed vacuum level in the working chamber to activate the vacuum pump and thus increase the vacuum level in the vacuum chamber over that produced by the vacuum source, whereby a greater pressure differential is available across the booster diaphragm before run-out is encountered. An optional sensor responsive to vacuum level in the vacuum chamber enables the vacuum pump to be additionally used for backup of the vacuum source while still providing the functionality of the invention in most cases. The venting of the vacuum pump to the vacuum source reduces released noise which might otherwise require bulky noise filter apparatus.

摘要： A self contained, supplemental vacuum assist unit is provided for use with a vacuum brake booster and a source of vacuum in a motor vehicle. The unit includes, within a single housing, an electric motor, an air pump driven by the motor, a manifold defining air exhaust and assist vacuum chambers, a pair of check valves permitting air flow from the pump outlet and the assist vacuum chamber to the air exhaust chamber, an outlet from the air exhaust chamber with a fitting for connection to the vacuum source, an opening from the assist vacuum chamber with a fitting providing communication directly to the interior of the vacuum chamber of the booster, and a pressure sensor including a diaphragm, plunger, magnet with a Hall effect sensor and motor control circuitry on a circuit board within the assist vacuum chamber. The unit is compact, light weight and efficient and is designed for attachment directly to the booster with no intervening vacuum hose therebetween.
