Abstract
A device for dampening pulsations of a fluid includes a case which includes an upper portion and a lower portion and a diaphragm elastically deformable between a rest position and a stressed position, arranged inside the case so that the diaphragm delimits, together with the lower portion, a fluid-tight chamber. More particularly, the diaphragm has, in the rest position, a general shape of revolution around a main axis of the device cambered towards the outside of the chamber. Furthermore, the profile of the diaphragm has according to an axial section of the diaphragm at least one undulation projecting towards the inside of the chamber in the rest position so as to form an area of preferred deformation towards the inside of the chamber in the stressed position of the diaphragm.
