The flap device (1) has a housing (2), in which a channel is formed. A fluid is flowable through the channel, where a flap body (4) is arranged in the channel. A bearing portion (9) has two bearing elements (16,17) and a connecting element (18), and is con...

The flap valve (1) has a flap housing (2) with a fluid channel section, where the fluid channel section has an inlet zone, a control zone and a discharge zone. A flap (4) is provided with a rectangular shape, at whose ends semi-circles are adjoined. The in...

A throttle valve for adjusting an amount of intake air to an internal combustion engine includes throttle shafts (32, 33; 73 - 75) disposed in an intake air passage (13) perpendicularly across the longitudinal axis of the air passage, and first and second ...

The switched flap valve has a valve flap (10) positioned in the engine air intake channel (12) and operated by a switching shaft (14), with a sealing gap between the peripheral edge of the valve flap and the wall of the air intake channel. The latter perip...

An intake air controller for an internal combustion engine is provided. The intake air controller comprises a throttle valve controlling a flow amount of intake air flowing into the internal combustion engine; a shaft integrated with said throttle valve an...

Efforts have been made in recent years to provide lightweight, low-cost throttle bodies by forming throttle bodies of resins. The bore of a throttle body must be formed so that the gap between the bore of the throttle body and a throttle valve placed in th...

To improve the efficiency of assembling multiple on-off valves into a manifold body and reduce resistance to rotation of a shaft after assembly, frame members (3) are fitted in downstream end portions of individual intake passage sections (12) of a manifol...

An opening end of a concave portion (20) of a bearing holder (16) is crimped to prevent an outer race (23) of a ball bearing (7) from sliding rearwardly, so that a bearing stop cover in the prior art is not needed to stop the slide-out of the outer race (2...
