The first inflow guiding portion has a plurality of through holes such that elastic deformation of the first inflow guiding portion reduces vibration when fluid flow into the cylindrical damping space from the master cylinder.

The invention relates to a fluid line (1), comprising a pipe (2), which has an inlet-side end segment (3) having a first connector (5) and an outlet-side end segment (4) having a second connector (10), wherein a cavity (17) bounded in the radially inward direction by at least one auxiliary element (16) is formed in the pipe (2). The problem addressed by the invention is that of minimizing the requirements for the suction performance of a pump that is used to convey a liquid through the pipe. This problem is solved in that a volume reduction element (18) is arranged in the cavity (17) at least in the region of the outlet-side end segment (4).

The present invention relates to a device (1) for the generation of micro and nano bubbles of gas in a liquid comprising: an outer tubular body (10) with an extension along a longitudinal axis a-a; an inlet (20) for a flow of liquid; an outlet (30) of the flow of liquid in fluid communication with said inlet (20); a central body (40) contained in a central area of said outer tubular body (10). The central body (40) comprisesa pre-chamber (41) containing a gas; an air intake (42) in connection with said pre-chamber (41) and with an external source of gas; a converging element (52), configured to concentrate the flow of liquid at the inlet; a Venturi chamber (44) in fluid contact with said pre-chamber (41), configured to suck the gas from the pre-chamber (41) and generate micro and nano bubbles of gas in the liquid that passes through it.

Various connection units are disclosed. The connection unit can be configured to straighten a flow of air, such as to reduce the distance before the flow of air becomes substantially laminar. The connection unit can include a drag reduction unit. The drag reduction unit can be configured to redirect airflow to the center of the connection unit. The connection unit can include a wake diverting component configured to lift air away from the periphery of the connection unit and/or redirect the airflow towards a radial center connection unit.

A damping device for damping or avoiding pressure surges, such as pulses, in hydraulic supply circuits has a damping housing (1) surrounding a damping chamber and having a fluid inlet (35) and a fluid outlet (41). A fluid receiving chamber extends between the fluid inlet (35) and the fluid outlet (41). During operation of the device, a fluid flow crosses the damping chamber in a throughflow direction (11), from the fluid inlet (35) to the fluid outlet (41). Parts of the fluid receiving chamber extend transversely with respect to the throughflow direction (11). More than one fluid receiving chamber is arranged one after the other in the throughflow direction (11). The fluid receiving chamber that is first upstream and the fluid receiving chamber that is last downstream immediately adjoin the fluid inlet (35) and the fluid outlet (41), respectively.

A damping device, in particular for damping or avoiding pressure surges, such as pulses, in hydraulic supply circuits, preferably in the form of a silencer, has a damping housing surrounding a damping chamber and having a fluid inlet (3) and a fluid outlet (5). A fluid receiving chamber (7) extends between the fluid inlet and the fluid outlet. A fluid flow crosses the damping chamber in a throughflow direction (11) from the fluid inlet (3) to the fluid outlet (5). Parts of the fluid receiving chamber (7) extend transversely with respect to the throughflow direction (11). The fluid receiving chamber (7) immediately adjoins the fluid inlet (3) and the fluid outlet (5). A guide element (51) is provided in the damping chamber. The fluid flow flows against the guide element changing the flow speed of the flow at least in sections.

A flow conditioner for use in a conduit includes a ring having a plurality of stepped elements disposed on an inner surface of the ring. A method for conditioning fluid using a flow conditioner includes coupling a flow conditioner to an interior surface of a conduit, flowing fluid through the conduit, contacting a surface of the flow conditioner with the flowing fluid, positioning a flow meter downstream of the flow conditioner, and measuring the flow profile of the fluid with the flow meter. Contacting the flow conditioner reduces one or more disturbances in a flow profile of the fluid. A flow conditioner includes a ring having at least one of a stepped element formed on an inner surface of the ring or a fin assembly coupled to the ring.
