Abstract

The invention relates to a fluid control device, in particular an air intake shifter, which comprises a housing with one first port having a first main axis perpendicular to the cross section of the first port and with at least one second port having at least one second main axis perpendicular to the cross section of the at least one second port. The first main axis and the at least one second main axis are aligned off-axis to one another. A control means is arranged within the housing to control a fluid flow between the first port and the at least one second port. The control means comprises a valve body being rotatable around the first main axis of the first port, whereas the valve body comprises a fluid path for guiding the fluid through the valve body.

Description

technical field [0001] The present invention relates to a fluid control device, in particular to an air intake converter for an air duct of an internal combustion engine of a vehicle, and more particularly to a turbocharged engine such as a single-stage turbocharged engine) charge air duct. Background technique [0002] Within the meaning of the present invention, charge air is to be understood as compressed air compressed by an exhaust-gas turbocharger or other types of superchargers or compressors. [0003] For turbocharged engines, the geometry (diameter and length) of the charge air duct (also known as the charge air delivery duct) is tuned to benefit from the pressure waves used to improve the air filling in the engine cylinders and thereby increase output torque. [0004] However, the optimal geometry of the charge air duct depends on the engine speed. When the engine speed is high, say above 1500rpm (revolutions per minute) or so, and the load is also high, the tur...
