Abstract

A supply pump (1) has an inlet valve (12) for controlling suction of fuel into a pressurizing chamber (3a) and also has an outlet valve (13) for controlling delivery under pressure of the fuel from the pressurizing chamber (3a). The inlet valve (12) and the outlet valve (13) are coaxially arranged in a valve case (14) and are guided by a common valve body (21). A valve seat (22) of the inlet valve (12) is constructed as a separate body from the valve body (21).
