Abstract
A pump apparatus installed in a cooling system of an internal combustion engine includes: a first housing member having a generally circular recess portion; a pump rotor placed within the recess portion; and a second housing member that is fixed to the first housing member so as to define a pump operation chamber that corresponds to the recess portion. The first housing member includes a housing body portion in which the recess portion is formed, and a discharge-side cylindrical portion formed integrally with the housing body portion so as to define a discharge passageway of the cooling water. The second housing member includes a cover portion that covers an opening end side of the recess portion, and a suction-side cylindrical portion that is formed integrally with the cover portion so as to define a suction passageway of the cooling water.
