Abstract
An electric pump includes a transmission unit that transmits rotational drive of a motor unit, a pump unit, and a rotary valve unit. The pump unit expands and contracts a pump chamber to draw in a fluid from an inlet and discharge the fluid from an outlet. The rotary valve unit includes a valve body and a valve cover. The valve body is rotated by the rotational drive force transmitted by the transmission unit. The valve cover includes a valve-side inlet that draws in a fluid and a plurality of fluid outlets that discharges the fluid to the exterior. The rotary valve unit is configured to switch the fluid outlets that come into communication with the inlet in accordance with rotational drive of the valve body. The valve body is intermittently driven by an intermittent drive mechanism that converts continuous drive corresponding to the rotational drive force into intermittent drive.
