Abstract
A carburetor has a throttle member in the form of a slide for controlling the air induction passage, the slide being displaceably guided in a sealed and sliding manner on planer edge areas of guide surfaces of a surface extending substantially at right angles to the induction passage, the slide being relieved from vertical downward pressures exerted on the guide surfaces by the manifold vacuum acting on the underside of the slide by an unloading mechanism controlled by the vacuum force, the unloading mechanism comprising lifting rails which are pivotally mounted for engagement with the slide and include rollers that may be raised or lowered by devices that are responsive to the change in vacuum below the slide as the slide moves closed or open to counteract the differential pressure force acting on the slide.
