Abstract
A low-pressure pump portion pumps fuel from a fuel tank. A pressure regulating valve controls pressure of fuel discharged from the low-pressure pump portion. A high-pressure pump portion pressurizes the discharged fuel. A valve cover has a mounting portion mounted with the pressure regulating valve. A camshaft moves a movable member to pressurize fuel in a high-pressure pump chamber of a cylinder so as to press-feed the fuel from the high-pressure pump portion. The low-pressure pump portion includes a rotatable member, which is rotatable integrally with the camshaft, and a pump cover, which accommodates the rotatable member. The pump cover is fixed to the pump housing. The valve cover is a separate component from the pump housing and the pump cover.
