  • Miniature pump, cooling system and portable equipment
    Patent number: 6755626
    Abstract: A miniature pump includes a miniature pump portion including a suction passage through which a liquid flows in, and a discharge passage through which the liquid flows out, and a bubble trap portion for blocking an entry of air bubbles into the miniature pump portion. Since the bubble trap portion prevents the entry of air bubbles into the miniature pump portion, a deterioration of pump characteristics owing to the entry of air bubbles can be suppressed, making it possible to obtain a miniature pump that achieves both a large discharge flow rate and stable discharge flow rate characteristics.
