The invention provides an apparatus for adjusting the flow of a fluid within a conduit, comprising a slide plate with a flat body and a fixed plate with a flat body. The slide plate and fixed plate have openings on their bodies. At a fully closed position, the openings of the slide plate do not substantially overlap with the openings of the fixed plate. By rotation of an actuator shaft and drive pin disposed thereon, the slide plate may move relative to the fixed plate, whereby the openings of the slide plate begin overlapping with the opening of the fixed plate, thereby allowing flow of fluid through the openings. Sequentially or independently from the movement of the slide plate, rotation of the actuator shaft may cause the fixed plate to rotate relative to the walls of the conduit, whereby flow of fluid may pass through the opening between the conduit and fixed plate assembly.

A first tubular and a second tubular define a fluid passage. A feather is positioned within the first tubular. The feather is configured to axially translate towards the second tubular and pivot towards a center of the first tubular. The feather includes a hinge on a pivoting end. A first end of a spring is coupled to the feather and a second end of the spring is coupled to the first tubular. The spring is loaded to actuate a movement of the feather between an open position and a closed position. A trigger is positioned between the first tubular and the second tubular to provide an interference with the feather. The interference retains the feather in the open position when the first tubular and second tubular are coupled.

An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir is described. The overfill valve includes a valve body positioned within the drop tube segment and a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. The non-contact valve actuator has a first position in which the non-contact valve actuator does not actuate the valve body from the open position to the closed position in a second position, achieved when the liquid reservoir reaches a predetermined level approaching the capacity of the liquid reservoir, the non-contact valve actuator actuating the valve body from the open position to the closed position when the non-contact valve actuator obtains the second position.

A turbocharger for an internal combustion engine has a bearing housing, in which a rotor shaft is mounted in a rotatable manner. A compressor having a compressor wheel is arranged for conjoint rotation on the rotor shaft. A fresh air supply channel conducts a fresh air mass flow to the compressor wheel. The fresh air supply channel has a first flow cross section upstream of the compressor wheel. A flow control device is provided and is adjustable between an open position, in which the first flow cross section is opened up, and a closed position, in which the first flow cross section is reduced to a second flow cross section. The flow control device is fluidically coupled to a compressor channel of the compressor downstream of the compressor wheel, such that the flow control device is adjusted in a manner dependent on a pressure prevailing in the compressor channel.

A fitting for shutting off and/or regulating flows of substance for use in pressure ranges above 50 bar has a housing body and a valve disc which can be operated from a drive lying outside the housing body via a valve shaft. The housing body is provided with a maintenance opening that can be shut off in a pressure-tight manner by a self-sealing lid that has a seal. In order to allow objects that are as large as possible, in particular the valve disc, to be guided through the maintenance opening during inspection works, without increasing the weight of the housing body, the maintenance opening has a rectangular passage cross section. In contrast to known circular maintenance openings which are known in this pressure range, a rectangular passage cross section permits a smaller surface area for the passage cross section and therefore a lighter housing body.

A valve seat has an inner passage and outer passages. A suction valve member has first passages and a first projection portion that guides, to the first passages, the fuel that flows from a pressure chamber at the time of valve opening. Therefore, an action force by the dynamic pressure applied to the suction valve member in the valve closing direction is reduced. An action force by the pressure of fuel that flows into pressure equalization grooves counterbalances the action force by the dynamic pressure of the suction valve member. Therefore, self-closing by the dynamic pressure can be inhibited, and the maximum output of an electromagnetic driving unit can be reduced. Fuel flows through a passage radially outside the suction valve member and the first passages. A fluid passage area is securable even when a lift amount of the suction valve member is small.
