Abstract
A liquid pump includes: a casing; a feed pipe bringing liquid from outside the casing to inside the casing; a pump mechanism provided in the casing and including a suction hole for sucking in the liquid and a discharge hole for discharging the liquid sucked in via the suction hole; a suction space positioned in the casing on a suction-hole inlet side and making a flow path formed by the feed pipe and the suction hole communicate with each other; and a discharge space positioned on a discharge-hole outlet side in the casing and communicating with the discharge hole. The suction space includes a gas accumulation area that is positioned above a center of an opening at casing-side end of the feed pipe, when viewed vertically and that accumulates gas brought into the casing through the feed pipe together with the liquid to separate the gas from the liquid.
