A pressure pulse damping device which is used in a liquid passage having a bottom flat wall. The flat wall has an opening therethrough with a flexible diaphragm positioned therein. The side of the diaphragm opposite the liquid passage is in communication with a gas chamber having gas therein. The diaphragm is movable such that the effective volume of the gas chamber is varied to ensure that the average pressure of the gas therein is substantially equal to the average pressure of liquid in the liquid passage.
