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.

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 hydraulic system for a working machine includes a hydraulic actuator having a first fluid chamber and a second fluid chamber, an accumulator, an outputting fluid tube to output an operation fluid, and a switching valve to be switched between a first position and a second position. The first position allows the first fluid chamber and the second fluid chamber to be communicated with the outputting fluid tube and thereby allowing a floating operation. The second position allows the first fluid chamber and the accumulator to be communicated with each other, allows the second fluid chamber and the outputting fluid tube to be communicated with each other, and thereby allows an anti-vibration operation.

摘要： An accumulator includes a pressure vessel including a first section and a second section joined to each other via a joint portion and a partition portion separating an interior space of the pressure vessel into a liquid chamber and a gas chamber so that a volume ratio between the liquid chamber and the gas chamber in the pressure vessel is variable. The first section includes a thread portion for fastening the accumulator to a support member. The second section includes an abutting portion disposed opposite to the thread portion across the joint portion in an axial direction of the thread portion and configured to abut on the support member when the accumulator is fastened to the support member.

摘要： A pulsation damper includes: a case in which a fuel chamber is defined; and a damper unit arranged in the fuel chamber to attenuate pressure pulsation of fuel. The damper unit has a diaphragm that is elastically deformed by receiving pressure of fuel, and a plate having a rigidity higher than that of the diaphragm. A gas chamber is defined between the diaphragm and the plate joined with each other.
