The invention provides an apparatus for adjusting the flow of a fluid within a conduit, comprising a slide plate with a flat body and a fixed plate with a flat body. The slide plate and fixed plate have openings on their bodies. At a fully closed position, the openings of the slide plate do not substantially overlap with the openings of the fixed plate. By rotation of an actuator shaft and drive pin disposed thereon, the slide plate may move relative to the fixed plate, whereby the openings of the slide plate begin overlapping with the opening of the fixed plate, thereby allowing flow of fluid through the openings. Sequentially or independently from the movement of the slide plate, rotation of the actuator shaft may cause the fixed plate to rotate relative to the walls of the conduit, whereby flow of fluid may pass through the opening between the conduit and fixed plate assembly.

A turbocharger for an internal combustion engine has a bearing housing, in which a rotor shaft is mounted in a rotatable manner. A compressor having a compressor wheel is arranged for conjoint rotation on the rotor shaft. A fresh air supply channel conducts a fresh air mass flow to the compressor wheel. The fresh air supply channel has a first flow cross section upstream of the compressor wheel. A flow control device is provided and is adjustable between an open position, in which the first flow cross section is opened up, and a closed position, in which the first flow cross section is reduced to a second flow cross section. The flow control device is fluidically coupled to a compressor channel of the compressor downstream of the compressor wheel, such that the flow control device is adjusted in a manner dependent on a pressure prevailing in the compressor channel.

A first tubular and a second tubular define a fluid passage. A feather is positioned within the first tubular. The feather is configured to axially translate towards the second tubular and pivot towards a center of the first tubular. The feather includes a hinge on a pivoting end. A first end of a spring is coupled to the feather and a second end of the spring is coupled to the first tubular. The spring is loaded to actuate a movement of the feather between an open position and a closed position. A trigger is positioned between the first tubular and the second tubular to provide an interference with the feather. The interference retains the feather in the open position when the first tubular and second tubular are coupled.

This disclosure relates to a valve assembly for a motor vehicle, such as a pressure relief valve (i.e., an air extractor), and a method of using the same. In an example, the valve assembly includes a flap moveable to between an open position and a closed position, a slider moveable along an axis and including an integrally formed arm in contact with the flap, and an electromagnet configured to be selectively activated to move the slider along the axis.

A valve assembly and a method of additively manufacturing the same are provided. The valve assembly includes a valve housing defining first and second mounting features, such as recessed dimples or protruding bumps, positioned on opposite sides of a substantially cylindrical channel to define a hinge axis. One or more valve flaps are positioned within the cylindrical channel, each valve flap including a hinge member extending along the hinge axis and defining two or more complementary features or coupling members for engaging either the mounting features of the valve housing or an adjacent hinge member.

Device for admitting cooling air to a motor vehicle interior, formed of one or several mobile flaps, each orientable in rotation about an axis by a control mechanism, each flap includes on its external periphery a pressing surface intended, when the mobile flap is in the closed position, to come into contact with a bearing surface. The pressing surface has a point of first contact and a point of last contact with the said bearing surface, these points being defined in such a way that when the control mechanism actuates closure of the mobile flaps and the point of first contact comes into contact with the said bearing surface, the point of last contact is distant from the said bearing surface by a predefined and non-zero distance.

An arrangement for controlling flow includes a flow control element, an actuator, a linkage assembly, and a sensor module. The linkage assembly is coupled between the flow control element and the actuator, and includes a rotatable linkage element coupled to impart force to the flow control element. The sensor module is affixed to the rotatable linkage element. The sensor module includes a MEMs-based strain gauge affixed to a substrate and operably coupled to measure torque on the linkage element, and a processing circuit disposed on the substrate. The processing circuit is operably coupled to receive torque measurement information representative of the measured torque. The processing circuit generates a fluid flow measurement value based on the torque measurement information and position information representative of a position of a flow control device of the flow control element. The flow control device is mechanically coupled to the rotatable linkage element.

A multi-blade dosing valve comprising the following elements: a valve body provided with a central opening; a plurality of shafts, each provided with a respective blade, which extend transversely to the central opening; the blades being able to close, at least partially, the central opening; a motor unit which causes the opening/closing of the blades; and vibrators to set in vibration the shafts and the blades. The multi-blade dosing valve comprises an independent vibrator for each shaft.
