A washer pump for an automobile includes a substantially circular pump chamber receiving concentrically therein an impeller and having an inlet aligned with the center of the impeller and first and second outlets defined in a sidewall of the pump chamber and extending tangentially to the sidewall, and a directional control valve including a valve chamber connected in fluid communication with the pump chamber through the first outlet and also through the second outlet, and a valve element movably disposed in the valve chamber for selectively connecting the first and second outlets, respectively, to first and second washer nozzles of the automobile. The washer pump further includes a projection disposed between the first and second outlets and projecting inwardly from the sidewall of the pump chamber toward the impeller for substantially blocking the flow of a cleaning fluid between the first and second outlets, thereby increasing the pressure difference between the first and second outlets.
