Abstract
The invention relates to a fluid conveyance system for a fluid, comprising a low-pressure conveyance system having a low-pressure pump () and a high-pressure conveyance system having a high-pressure pump (), which are connected by means of a connecting line, wherein the fluid conveyance system has a pressure damper (). According to the invention, a fluid conveyance system is provided, by means of which a pulsation of the fluid caused by flow-rate waves or pressure waves in the fluid is damped. This is achieved in that the pressure damper () is arranged in the lower-pressure conveyance system and is a hydraulic pressure damper (). Said hydraulic damper () has a piston () arranged in a cylinder (), which piston can be moved against the force of a compression spring () and the vapor pressure present in a compression-spring chamber () accommodating the compression spring.
