Metal diaphragm type pulsation absorber for high-pressure fuel pump

摘要

To improve the rigidity of diaphragms, a plurality of diaphragms of the same thickness and size are placed one upon another, the total thickness of the diaphragms is a value obtained by multiplying the thickness of the diaphragm by the number of diaphragms, and the peripheral portions of the diaphragms are sealed and supported by a high-pressure container.
