摘要： A rotary throttle valve having a first cylindrical bore for flow of air between an inlet and an outlet and a second cylindrical bore orthogonal to the first bore and being substantially the same diameter as the first bore. A flow modulator rotatably disposed in the second bore has first and second cylindrical portions disposed respectively on opposite sides of the first bore and separated by a central plate such that when the modulator is rotated to place the plate transverse to the first bore, the edges of the plate are fully engaged with the wall of the second bore and the valve is closed. As the modulator is rotated from the closed position to open the valve, the edges of the plate become progressively less engaged with the wall of the second bore, the edge of the open area following the juncture lines of the first and second bores.

摘要： A throttle valve for controlling air flow to an internal combustion engine in which a throttle valve body is mounted in an intake channel to control air flow through the intake channel to the internal combustion engine. A spindle is rotatably supported crosswise in the intake channel and the throttle body is secured to the spindle for rotation therewith between closed and open positions. The intake channel has a wall with an inside surface of elliptical cross-sectional shape, the throttle body being formed as a planar disk having a circular periphery. The throttle body in the closed position is inclined with respect to the inside surface of the wall and the opposite edges of the valve body are in peripheral contact with the inside surface.
