ABSTRACT:
In this pulsation absorbing device, a cylindrical resilient protective diaphragm and an inner cylinder formed with one or more communicating holes are disposed within a cylindrical pressure vessel being in concentrical with each other.
Along the outer surface of the inner cylinder one or more arched resilient valve members and one or more leaf springs being laminated with each other are disposed capable of being raised or lowered depend upon the extent of the fluid pressure, thereby the arched valve member can be separated in its function of valve action and spring property, therefore the both members are strengthened by the lamination as well as their deformation and extent of fatigue can be kept minimum.
