The valve (1) has a venturi control unit (2) in which a flap shaft (3) is supported. A flap (4) is symmetrically arranged on the shaft in an inclined manner so that the flap is attached at an inner side (6) of the control unit in a closed condition of the ...

The present invention relates to a valve device (1) for regulating a fluid, comprising a valve body (3) fixed to a support spindle (4) extending transversely into said portion and mounted with the ability to rotate therein, said conduit portion comprising,...

Leaf elements (5) are arranged at the outer edge region of the switching flap base body (4). The leaf elements lie against a bead-shaped ridge of an inner wall of the air duct system, in the closed state of the switching flap (1), and thereby seal the air ...

A throttle valve (10) includes a downstream valve half (14) and an upstream valve half (15). Rectifying fins (18) are arranged on the upstream side surface of the downstream valve half. The rectifying fins relax the energy of intake air stream flowing alon...

The present invention relates to a fuel-heating type fuel injection apparatus, at the startup of the engine (1), able to prevent fuel-attaching on the wall of the intake passage (34) and eliminate hydro carbons in the exhaust. A fuel-heating type fuel inje...

The throttle valve assembly has a housing (2) with air duct (3) and disc-like throttle valve (4) swivel mounted on a drive shaft (7) and with a bore (5) and an at least partially rounded sleeve face (8) with two surface parts and two transition faces. The ...
