    摘要： An apparatus for coupling to a fluid delivery system and for receiving a fluid into the apparatus; a portion of the apparatus permitting a change in shape or size to accommodate the fluid volume or pressure received therein. The apparatus including a housing with a cavity, an expandable reservoir with an opening and a passage, and a cap; the expandable reservoir positioned within the cavity and coupled to a fluid source. The expandable reservoir includes an unrestrained orientation when a fluid volume or pressure therein is below a threshold, and an expanded orientation, when the fluid volume or pressure therein is above the threshold; the expandable reservoir moving toward the expanded orientation to accommodate a fluid volume or pressure received through an opening, and the expandable reservoir moving toward the unrestrained orientation to direct a fluid volume or pressure through an opening.

    摘要： A dampening valve unit, for use in a liquid distribution system is disclosed. A feeding conduit is evacuated of liquid after an associated tap unit is closed and refilled with liquid after the tap unit is opened. The dampening valve unit comprises a dampening chamber, connectable to said feeding conduit, and a liquid stop valve unit, connectable at an inlet end thereof, to said associated feeding conduit and which has an outlet end being connectable to said associated liquid tap unit. Said dampening chamber is adapted to collect gas and is connectable to said associated feeding conduit via a passage. The passage is directly connected, without any restrictions therebetween, also to a liquid stop valve at said inlet end. The passage is always open at the dampening chamber for fluid connection between the passage and the dampening chamber.

    摘要： Liquid accumulators and methods for reducing pulsations of a liquid flow are disclosed. A liquid delivery system comprises a pump configured to drive liquid to a pipe. The pipe is configured to transmit a liquid flow. A liquid accumulator is fluidically connected to the pipe. The liquid accumulator comprises a chamber containing the liquid and a vapor column and a power source configured to input energy to the chamber to generate vapor from the liquid to form the vapor column. The vapor column constitutes a gas spring to reduce pulsations of the liquid flow in the pipe. The spring rate of the gas spring can be adjusted by changing the input energy level from the power source to the chamber.

    摘要： A conduit connection assembly includes a first conduit part and a second conduit part, assembled to form a conduit connection delimiting a first fluid conducting volume from a second fluid conducting volume. The first and second fluid conducting volumes communicate with each other via a pressure change inducing device. During use of the conduit connection assembly, the pressure in the first conducting volume is higher than the pressure in the second conducting volume. A cavity is formed between the first and second conduit parts at a distance from the first fluid conducting volume, and a draining connection is adapted to provide a communication between the cavity and the second fluid conducting volume. A slot, formed by the assembly of the two conduit parts, provides a communication between the first fluid conducting volume and the cavity.
