摘要： A valve, such as a ball valve, can include a noise attenuation assembly to control fluid expansion through the valve and provide noise abatement. The valve can include a valve body and a valve stem and the noise attenuation assembly can include a flow control body and a trim body. The flow control body can be coupled to the valve stem and the flow control body can be configured to selectively permit fluid flow through the valve body in an axial direction. The trim body can include a plurality of channels to control fluid expansion during fluid flow through the valve body. The trim body can be engaged with the flow control body at first and second mounting structures of the flow control body to secure the trim within a fluid pathway of the flow control body.

摘要： A valve stem for use in a fluid flow control valve having a valve body configured to receive a portion of the valve stem and to enable the valve stem to selectively rotate within the valve body between a fully-open position, where fluid is permitted to flow through the fluid flow control valve, and a fully-closed position, where fluid is prevented from flowing through the fluid flow control valve. The valve stem includes an elongate valve stem arm having a first end and a second end and a valve stem head integrally formed with and fixedly attached to the second end of the valve stem arm. The valve stem head includes a fluid inlet formed in the valve stem head, and a fluid outlet formed in the valve stem head, and a fluid passage that directs fluid from the fluid inlet, through the valve stem, and out of the fluid outlet.

摘要： A fluid-metering valve assembly for use in a coolant regulator of an internal combustion engine cooling system may include a main body and a metering member. The main body is configured to be rotatably secured within an internal chamber of the coolant regulator. A fluid passage is formed through the main body, and is defined, at least in part, by a metering edge of the main body. The metering member is formed proximate to the metering edge of the main body, and is configured to allow variable doses of fluid to be metered into or out of the coolant regulator as the main body is rotated within the coolant regulator. The metering member includes one or more linear features formed into the main body.

摘要： Ball valve with a housing which forms an inlet, an outlet and an obturator seat, an obturator which forms an inner cavity with an inlet aperture, an outlet aperture opposite the inlet aperture, an auxiliary aperture between the inlet aperture and the outlet aperture, as well as a closed side opposite the auxiliary aperture. The inlet aperture and the outlet aperture connect the inlet with the inner cavity and with the obturator seat and an outer channel is formed in an outer surface of the closed side which, when the obturator is rotated from a closed position towards an open position, opens a first outer flow passage between the obturator seat and the outlet before the outlet aperture opens a second inner flow passage between the inner cavity and the outlet.

摘要： A valve for a vacuum drainage system includes a valve body having an interior chamber operatively connectable to a suction device and through an outlet to a vacuum source. A movable member having an aperture is secured within the chamber and movable through points between closed and open positions to adjust the open area of the aperture and the fluid flow through the outlet. The aperture is configured such that during adjustment to increase the effective operational area of the aperture, a rate of change of the effective operational area increases non-linearly in relation to a linear increase in the distance of travel, while providing advantageous and more controllable linear adjustment of the applied vacuum. The aperture can have a trilateral shape including at least one curved side, or comprise a plurality of sub-apertures, and the movable member can comprise a rotary sleeve.

摘要： A fluid valve is described to help reduce oil sump pressures of a variable speed compressor and a fixed speed compressor working in parallel in a HVAC system. The fluid valve can be a ball valve. Openings of a variable flow through structure of the ball can be configured to elongate along an equator the ball. When the ball rotates along a rotation axis, a size of a variable fluid path formed between the openings can be varied, resulting in a variable pressure drop across the ball. In operation, when the variable speed compressor is operated at different operation speeds, the ball can be rotated to different positions relative to the rotation axis, which may help reduce the pressure differential between the sumps of the variable speed compressor and the fixed speed compressor.
