Abstract
A reservoir unit to be installed within a fuel tank, in order to prevent bubbles generated by the fuel transfer jet pump of the fuel tank from feeding into the internal combustion engine, comprising a wall formed in a closed bag shape so that the delivered flow of fuel can fully turn round the discharge port of a jet pump, against which fuel containing bubbles delivered from the jet pump hits and, after turning around a partition wall a plurality of times, fills the reservoir unit, with the result that bubbles can be removed from the fuel more efficiently and the fuel in the reservoir can be prevented from containing a large quantity of bubbles.
Claims16
A reservoir unit having an anti-bubble device comprising:
- a cylindrical reservoir having a bottom installed in a fuel tank,
- a fuel pump for sucking fuel in that reservoir,
- a pressure regulator for regulating pressure of the fuel delivered from the fuel pump at a constant level by allowing part of the fuel delivered from that fuel pump to escape,
- a jet pump for accepting that fuel escaping from the pressure regulator, generating a negative pressure by utilizing its flow velocity, and introducing fuel outside the reservoir into the reservoir with that negative pressure, and
- a wall which is located near the discharge port of that jet pump and against which the flow of fuel delivered from the jet pump hits.
