ABSTRACT:
The present invention is directed to a pulse dampener device especially effective for the efficient damping of high frequency pulses of relatively small amplitude. The invention is characterized by the provision of a low inertia diaphragm assembly disposed in intimately spaced relation to a conduit through which flows the fluid to be damped, said conduit including a rigid partition or baffle member providing for deflection of a substantial portion of the fluid flowing through the conduit to react against the diaphragm in a direction substantially perpendicular to the plane thereof and providing a tortuous path for the fluid from one side of the partition to the other before continuance of its flow.
