A high-pressure fuel pump includes an inlet, which is in the form of an inlet port fixed to the pump housing, and a pressure-limiting valve that fluidically connects a high-pressure region to a low-pressure region and opens in the direction of the low-pressure region. The pressure-limiting valve opens in the direction of an inlet port chamber.
