Abstract
A pulsation damper configured to reduce pressure variations in a pipe system. The pulsation damper comprises a first pipe section and a second pipe section. The first pipe section is at least partly placed inside the second pipe section such that a product flow can flow through the first pipe section and then through a space formed between the first pipe section and the second pipe section. Due to the increased cross sectional area of the second pipe section pressure variations can be damped efficiently.

A pulsation damper configured to reduce pressure variations in a pipe system,
- said pulsation damper comprising a first pipe section and a second pipe section,
- said first pipe section being at least partly placed inside said second pipe section, such that a product can flow through said first pipe section and through a space formed between said first pipe section and said second pipe section, and
- the first pipe section possessing a cross-sectional shape enclosing a volume and being made of an elastic material so that when pressure inside the first pipe section increases from a lower pressure state to a higher pressure state, the cross-sectional shape of the first pipe section changes to increase the volume in the first pipe section and thereby damp pulsation.
A pulsation damper configured to reduce pressure variations in a pipe system,
- the pulsation damper comprising a first pipe section and a second pipe section,
- the first pipe section being at least partly positioned inside the second pipe section to permit product to flow through the first pipe section and through a space formed between the first pipe section and the second pipe section, the space possessing a volume,
- the first pipe section possessing a cross-sectional shape enclosing a first volume and being made of an elastic material so that when pressure inside the first pipe section increases from a lower pressure state to a higher pressure state, the cross-sectional shape of the first pipe section changes to increase the first volume in the first pipe section and thereby damp pulsation, and
- the second pipe section possessing a cross-sectional shape and being made of an elastic material so that when pressure in the space between the first pipe section and the second pipe section increases from a lower pressure state to a higher pressure state, the cross-sectional shape of the second pipe section changes to increase the volume of the space between the first pipe section and the second pipe section and thereby damp pulsation.
A pulsation damper configured to reduce pressure variations in a pipe system, the pulsation damper comprising:
- a first pipe section and a second pipe section;
- the first pipe section being at least partly inside the second pipe section to permit a product to flow through the first pipe section and through a space formed between the first pipe section and the second pipe section;
- and
- at least one of the first and second pipe sections possessing a non-circular elliptical cross-sectional shape and being made of an elastic material so that when pressure inside the at least one of the first and second pipe sections increases from a lower pressure state to a higher pressure state, the cross-sectional shape of the at least one of the first and second pipe sections becomes less elliptical to damp pulsation.
