Abstract
A fuel supply device for internal combustion engines comprises a constant level chamber, an engine-driven fuel pump having an outlet connected to the constant level chamber and an inlet connected to a fuel reservoir through a pipe provided with a non-return valve. A capacity located on the pipe is defined by a wall movable between a first position where the capacity has a maximum volume and a second position where the capacity has a minimum volume. A spring continuously biases the movable wall towards the first position. The movable wall is drawn to the second position responsive to start up of the engine.
Claims5
A fuel supply device for an internal combustion engine, comprising:
- a constant level chamber,
- an engine-driven fuel pump having an outlet connected to said constant level chamber and an inlet connected to a fuel reservoir through a pipe provided with non-return valve means,
- a chamber located on said pipe between said non-return valve means and pump, defined by movable wall means movable between a first position where said chamber has a maximum volume and a second position where said chamber has a minimum volume,
- return means continuously biasing said movable wall means toward said first position, and
- driving means responsive to the depression at a point of an intake duct of the engine located downstream of a driver-controlled throttle member to move said movable wall means toward said second position.
