ABSTRACT:
The invention relates to a liquid pulsation dampener device for use in a piping network, including at least one hydro-pneumatic vibration dampener arranged at the delivery side of a positive-displacement pump. Such pumps are apt to impose normally undesirable periodic fluctuations or pulsations upon the liquid flow. The invention aims at providing a device suitable for manufacture at low cost and requiring a minimum of space while largely reducing pulsations of flow and of pressure in a piping network. In accordance with the invention, there is, at the delivery side of the positive-displacement pump and in addition to the hydro-pneumatic vibration dampener, a dynamically acting vibration dampener, and the hydro-pneumatic vibration dampener is arranged in a by-pass between the pump and the dynamically acting vibration dampener. The latter is designed for the attenuation of vibrations of higher frequencies, whereas the hydro-pneumatic vibration dampener is designed for the attenuation of low-frequency vibrations.
