Abstract: Provided is a strainer including: a filter paper filtering fuel and having a space part disposed therein; an inner rib disposed inside the filter paper; protruding parts protruding up and down from the inner rib to be disposed inside the filter paper; and a communicating pipe combined with the filter paper to communicate with the space part. The filter paper and the inner rib are partially folded up longitudinally. The folded portion is formed in a rounded form, and the upper and lower portions of the filter paper are formed not to contact each other at the folded portion. Widths of the protruding parts are each formed differently and distances between the protruding parts are each formed differently. The width and the distance are more narrowly formed at the portion at which the filter paper is folded than at the portion at which the filter paper is not folded.

Abstract: Provided is an electric water pump in which a portion of a fluid discharged from the vicinity of an outer peripheral edge of an impeller flows between the impeller and a lower casing, flows between a rotor and the lower casing, flows between a shaft and the rotor along a channel formed inside the rotor, and then flows to an inlet side of the impeller such that the fluid circulates outside and inside the rotor, and thus, foreign matters contained in the fluid do not accumulate in an accommodation space between the rotor and the lower casing, and thus, efficiency and durability of a motor can be improved.

Abstract: Provided are a strainer and a fuel pump module having the same, and more particularly, a strainer capable of preventing filter paper from stopping since the filter paper contacts each other at a portion at which the strainer is folded, in the strainer connected to an inlet of a fuel pump or a fuel pump module to filter fuel sucked thereinto, and a fuel pump module having the same.
