The hydraulic snubber insert can have an elongated stem and at least one segment extending transversally from the stem, each segment having a size and shape mating a cross-sectional size and shape of the liquid carrying line, and at least one aperture, the insert being configured for the at least one segment to be pushable snugly into the liquid carrying line and pullable out from the liquid carrying line via the stem.

An apparatus for a vehicle component venting system comprises a body having an inlet, an outlet, and a fluid pathway(s) therebetween through which air may pass, and a shield between the inlet and outlet configured to block liquid from passing from the inlet to the outlet. The inlet includes a first set of ports extending from an interior surface of the body through an exterior surface; and the shield and interior surface of the body define a void therebetween. A second set of ports extends through the shield and are in fluid communication with the void and a passageway extending between the shield and the outlet, the first and second sets of ports, the void, and the passageway form the fluid pathway between the inlet and outlet. The ports of the second set of ports are offset from and linearly misaligned with the ports of the first set of ports.

A throttle for a liquid pipe has at least one liquid duct for a liquid flowing through the throttle, the liquid duct extending along the longitudinal axis of the throttle. The liquid duct has at least one duct wall having a curved shape along the longitudinal axis.

An in-line ultrasonic attenuator (10) of this disclosure includes a longitudinally extending pipe (20) having a first and second end (21, 31), and a constant inside diameter extending an entire distance between the first and second ends. Instead of plates, the attenuator includes at least one helical baffle (23 or 33), or a first and a second helical baffle (23, 33) arranged in series with one another, coaxial to the longitudinal center line of the longitudinally extending pipe. The first helical baffle has a first twist rotation and the second helical baffle has a second twist rotation opposite that of the first twist, each twist rotation being at least 180°. The pipe ID can be the same as that connected to the ultrasonic gas flow meter. No elbows are required at the front or back end of a measurement skid of which the attenuator is a part.

The present invention concerns an attenuation device (1) of the fluid flow pulsation along a duct of a hydraulic circuit connected with a hydraulic machine, comprising at least an attenuation module (3) passed through by a pass-through duct (5) configured to be placed in fluid communication with said duct of said hydraulic circuit. In particular, in said attenuation module (3) a first duct (7) is obtained having an opened first end (70) in fluid communication with said pass-through duct (5), and a closed second end, said first duct (7) extending along a curved line comprising a plurality of curved sections, said first duct (7) being adapted to attenuate the pulsation of said fluid flow along said duct of said hydraulic circuit to reduce the vibrations generated by said pulsation of said fluid flow.

An impact reducer for drainage stacks includes a first pipe section with a first internal passage having at least five alternating bends along its longitudinal axis, a bypass vent in a second pipe section having a second internal passage parallel to the longitudinal axis and a clean out plug in a third pipe section having a third internal passage at a radial angle with the longitudinal axis. First and second end fittings are located on the impact reducer for connecting the device to a drainage pipe. The impact reducer adjusts the turbulent flow of water falling in the drainage stack, converting the turbulent flow to laminar flow before the lower bend fitting of the drainage stack, which protects the lower bend fitting from impact shock.

Leakage components are described herein. The leakage component includes a first tubing housing and a plurality of leakage ports. The first tubular housing defines a first flow path between a first end portion and a second end portion. The plurality of leakage ports are formed in the first housing and in fluid communication with the first flow path. The fluid flow through the plurality of leakage ports is configured to entrain ambient air into the fluid flow exiting the plurality of leakage ports to decelerate the fluid flow.

A damping device, in particular for damping or preventing pressure surges, such as pulsations, in hydraulic supply circuits, preferably in the form of a silencer, having a damping housing (2) encompassing a damping chamber (10), wherein said damping housing (2) has at least one fluid inlet (6) and at least one fluid outlet (8) as well as a fluid receiving chamber extending between the fluid inlet (6) and the fluid outlet (8), wherein during operation of the device a fluid flow coming from the fluid inlet (6) passes through the damping chamber (10) towards the fluid outlet (8) and wherein a wall part of the fluid receiving chamber extends as a guide element (16) in at least one direction of extension transverse to the direction of the fluid flow, is characterized in that in the damping chamber (10) several guide elements (16) are provided, against which the fluid can flow and which alter the flow velocity in certain areas.
