Cavitation Inception in Spool Valves
Cavitation has been investigated in directional control valves in order to identify damage mechanisms characteristic of components o f aircraft hydraulic systems. Tests have been conducted in a representative metal spool valve and in a model three times larger. Data taken under noncavitating conditions with both valves showed that the position of the high-velocity annular jet shifts orientation...

Performance and Behavior of Seals for Pneumatic Spool Valves
This article presents a seal development approach that takes actual operating conditions (mounting, sealed pressure, lubricating conditions), seal material, and counterpart machining tolerances into account. The approach was applied to the design of seals for a commercial pneumatic spool valve. A single seal geometry and two seat configurations were specified on the basis of finite element anal...
متن کاملSpeaking valves: influence of the fatigue on the flow characteristics
The in vivo operation of a speaking valve consists of two stages: 1) air passes through the razor-thin slit, the dome opens and the patient can speak; 2) the dome is closed and the patient cannot speak. The valve is thus subject to fatigue, as its service life is made up of a certain number of opening/closing cycles. Two types of valve were investigated: the Staffieri valve and a new valve prot...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
