The invention discloses a fuel pump having an outlet valve in the piston and a fuel path flowing around the actuator. The fuel pump for delivering fuel, comprises a casing (10), a cylinder (4), a piston (5) which is arranged in the cylinder (4), a heat-producing actuator (6) for actuating the piston (5), and a return element (7) for returning the piston (5) to a starting position, a first gap (8), which is formed at the heat-producing actuator (6), in particular between the cylinder (4) and the heat-producing actuator (6), wherein a first fuel path (80) passes through the first gap (8), an inlet valve (2), an outlet valve (3), wherein the outlet valve (3) is arranged in the piston (5) and the piston (5) has a passage (16), via which a fuel can flow from the outlet valve (3) in the direction of the first gap (8).
