A shrouded valve assembly includes a valve with a valve pipe and a valve channel. A valve member in the valve channel can regulate flow of fluid through the valve channel. A valve shroud provides a valve shroud chamber. First and second shrouded pipe assemblies are on opposite sides of the valve, each including a pipe in fluid communication with a respective end of the valve channel, and a pipe shroud providing a pipe shroud chamber. Each pipe shroud chamber is in fluid communication with a respective end of the valve shroud chamber. The pipe assemblies are connected to the valve shroud by first and second connections and to the valve by third and fourth connections, the fourth connection more flexible than both the first connection and the second connection. Load passes between the pipe assemblies via the valve shroud rather than via the valve, protecting the valve from damage.

A shrouded valve assembly including a valve, valve pipe and valve channel. A valve member can regulate flow of fluid through the valve channel. A valve shroud provides a valve shroud chamber and includes first and second valve shroud members fixed via valve shroud member flanges. An actuator shaft passes through the valve shroud and the valve pipe to the valve member and can move to operate the valve member to regulate flow of fluid through the valve channel. The actuator shaft extends in an actuator shaft direction passing through the valve shroud and the valve pipe. The valve shroud flanges meet at a valve shroud interface inclined at an acute angle to the actuator shaft direction. The actuator shaft passes through the first valve shroud member and not the second valve shroud member, enabling the valve to be inspected by disassembling this interface without disassembling the valve shroud members.

Embodiments of the present disclosure present a valve assembly that includes a valve body having a gas passage bore, a valving bore extending along a longitudinal axis and intersecting the gas passage bore, a first bearing surface concentric with the longitudinal axis and a radially spaced apart second bearing surface concentric with the longitudinal axis, wherein an interface of the gas passage bore and the valving bore defines a flow port radially intermediate the first bearing surface and the second bearing surface. The valve assembly further includes a shaft valve extending along the longitudinal axis and rotatably mounted in the valving bore.

A valve for an exhaust gas line of an internal combustion engine in which a closure body is arranged in a duct and is positioned in a recess of a shaft, the closure body being pivotable about a rotation axis of the shaft. The closure body has two sides and a circumferential surface arranged between the two sides. The circumferential surface has sections with different external dimensions. A first external dimension of the circumferential surface of the closure body in a first section is smaller than the smallest internal dimension between end regions of the recess of the shaft in which the closure body sits. A second external dimension of the circumferential surface in a second section is greater than the smallest internal dimension of the recess of the shaft. The circumferential surface contacts the shaft in each of the two end regions of the recess.

A throttle valve includes a housing, an electric motor and an insert. The electric motor is accommodated in the housing and drives opening and closing of an air flow passage of the throttle valve. The insert is partially enclosed in the housing and includes an electrically conductive insert body at least partially accessibly exposed from the housing, and an electrically conductive electric motor connector. One end of the motor connector is electrically connected to the insert body, and the other end thereof is electrically connected to the electrically conductive housing of the electric motor.

A valve assembly can include a valve body, a seat, and a seat cover. In one aspect, the valve body can include an inner surface and an outer surface. The inner surface can define a body bore and a valve body groove having a bottom groove surface. The seat can include an inner surface defining a seat bore and an outer surface defining a seat alignment rib configured to be positioned in the valve body groove. In one aspect, the valve body groove can define a deformation gap between the bottom groove surface and an outer surface of the seat alignment rib. The seat cover can include an inner surface defining a seat cover bore. In one aspect, the seat cover can be mounted on the seat with an outer surface of the seat cover facing the inner surface of the seat.

An intake control valve includes a valve body being made of resin, the valve body configured to be pivotally mounted to a surge tank of an internal combustion engine, the valve body pivoting between an open position and a closed position to for opening and closing a fluid passage formed at a division wall, the division wall dividing inside of the surge tank into two portions; and a bearing being made of metal, the bearing being integrally provided with a first end portion of the valve body by insert molding when resin molding the resin-made valve body.

The invention relates to a valve device for a motor vehicle, comprising a housing, a flow channel located in the housing, a flap arranged in the flow channel for closing the flow channel, the flap having regions in which a pin penetrating the flap is fastened and the pin being rotatably mounted in the housing, and a valve seat, which is arranged in the flow channel and which is in contact with the flap when the latter is in the closed position. The flow channel is provided with a plasma coating which renders it hydrophobic or hydrophilic.

Valve assembly (10) comprises two valve portions, an upper and lower valve portion (12,24), each having a valve housing indicated generally at (16,18) which are generally annular and a valve closure member (20,20′) which is pivotally mounted within the housing. The valve closure member (20,20′) is in the form of an annular disc and is provided with spindles (22,22′) by means of which the valve closure member is pivotally mounted within the housing. The valve closure member (20,20′) and the spindles (22,22′) are machined from a single piece of metal.

A thrust plate for a butterfly valve includes a thrust plate body that defines a recess. The recess extends between a bottom thrust surface, side walls and an open top. A wear-resistant coating is located on the bottom thrust surface.
