摘要： An example fluid system can include a fluid noise suppressor having a resilient insert having an outer surface; wherein the resilient insert can be operable to dampen a fluctuation of a total pressure about a mean static pressure, providing effective noise reduction that without the resilient insert, would have occurred in the flowing fluid with the fluctuation; and wherein the mean static pressure can be between about 100 psig to about 10,000 psig.

摘要： A non-permanent protective insert which acts as a barrier to protect against flow induced erosion and contains an inlet flange which aids in extraction is disclosed. The non-permanent insert is able to customize its features and specifications to allow for infinite configurations. The non-permanent protective insert is able to withstand high-turbulence flow transition zones, varying temperature ranges, and various corrosive and erosive media and is used in simple to complex infrastructures.

摘要： A telescopic bladder with a noise reduction structure is provided. The telescopic bladder has an opening. The telescopic bladder includes a top plate and a plurality of connected annular bodies extending from a periphery of the top plate toward the opening. The annular bodies have a continuous wavy cross-section. An inner surface of at least some of the annular bodies is formed with at least one protrusion. When the telescopic bladder is applied to a pillow, even if the telescopic bladder is inflated or deflated in the middle of the night, there will be no annoying noise, thereby improving the sleep quality effectively.

摘要： A helical strake pole system that includes a tubular pole having a longitudinal axis and threaded attachment points. The system further includes a helical strake fin disposed circumferentially around a portion of the tubular pole along the longitudinal axis. The system further includes couplers disposed on the tubular pole. The couplers are configured such that each coupler has a first portion with a slot configured to receive an upper portion of the helical strake fin and a second portion configured to removably coupled to a threaded attachment point of the tubular pole. In addition, each coupler is configured to position a portion of the helical strake fin substantially perpendicular to a surface of the tubular pole.

摘要： A line element includes an inner element, an outer element surrounding the inner element, and a damping element arranged between the inner element and the outer element. The damping element can be made, for example, of knitted wire fabric or a stripwound hose. The damping element can be made in particular of a more easily wearing material than the outer element and/or the inner element, for example of copper.

摘要： A fluid delivery system including at least a housing for a charge-free pulsation dampener of a type utilizing elastomeric compression material, but without the compression material therein, includes a system pulsation dampener. The fluid delivery system includes a fluid reservoir, a fluid pump, a manifold, a pulsation dampener, and piping. The fluid reservoir stores a fluid used for a drilling procedure. The fluid pump pumps the fluid from the fluid reservoir through the fluid delivery system. The manifold is located downstream from the fluid pump, and receives and combines fluids from the at least one fluid pump. The pulsation dampener receives the combined fluid from the manifold, and dampens residual pulsations from the manifold. The piping receives fluid output from the pulsation dampener, and transfers the fluid received from the pulsation dampener further downstream.

摘要： An apparatus for a vacuum cleaner for compensating air pressure surges, where a first air flow is flowable in a first flow direction through the apparatus and a second air flow is flowable in a second flow direction through the apparatus, includes a main body having a first cross-sectional area of flow and a flow resistance element. A free end of the flow resistance element projects from the main body and produces a second cross-sectional area of flow. The first cross-sectional area of flow is larger than the second cross-sectional area of flow such that the second air flow flowable in the second flow direction is reduced.

摘要： A shower system includes a shower waterway and a fluid control valve. The shower waterway is configured to be coupled to a shower device. The fluid control valve is coupled to the shower waterway and comprises a valve body and a piston. The valve body includes a chamber and a reservoir. The piston is slidably coupled to the valve body and fluidly separates the chamber from the reservoir. The chamber includes a compressible gas. The piston is configured to slidably translate within the valve body to compress the compressible gas in response to a water pressure fluctuation in the shower waterway.
