Title: LIQUID PUMP
Abstract:
[Problem] To provide a liquid pump which is configured to inhibit the discharge of air in an air trap formed in a discharge-side tank. [Solution] A discharge-side tank part 28 formed within a housing 16 has a first inner lateral surface 28c and a second inner lateral surface 28d which are disposed to oppose each other in a horizontal direction in a state in which the liquid pump 10 is installed. The first inner lateral surface 28c has a discharge port 22 formed therein, while the second inner lateral surface 28d has formed therein an opening 46a of a discharge-side communication channel 46. Within the discharge-side tank part 28, an air trap A2 is formed in a space above the opening 46a of the discharge-side communication channel 46 and said discharge port 22. A cylindrical partition 48 is provided in the discharge-side tank part 28, and this cylindrical partition 48 protrudes toward the first inner lateral surface 28c from the second inner lateral surface 28d so as to cover the opening 46a of the discharge-side communication channel 46 as viewed from the air trap A2 side, at least at the upper position of the opening 46a.
