A control device for an internal combustion engine includes an intake channel, an exhaust gas recirculation channel which enters into the intake channel, a control element, a mixing housing which forms the intake channel, a connection element, a compressor, and a shaft. The mixing housing has a mouth of the exhaust gas recirculation channel in a lower area, an outlet, a mixing housing section, and a bowl-shaped recess. The cross-sectional extension is formed via the mixing housing to provide an axial stop face. The connection element abuts against the axial stop face and is radially limited by an axially opposite inner wall surface on the stop face. The mixing housing section has a recess arranged at the lowest point of the mixing housing section and below the axially opposite inner wall surface. The recess enters into the bowl-shaped recess of the mixing housing.

An exemplary manifold for a pharmaceutical ingredient compounding device can include a housing, at least one primary intake port including a primary valve to permit or block passage of at least one primary ingredient through the manifold, and a plurality of secondary intake ports. A first channel can be in fluid communication with the at least one primary valve and include an outlet port configured to outlet the at least one primary ingredient from the manifold. A second channel can be in fluid communication with a plurality of secondary valves and include an outlet port configured to outlet at least one of a plurality of secondary ingredients from the manifold. The first channel and second channel can be in fluid isolation from each other such that the at least one primary ingredient does not mix with the plurality of secondary ingredients within the manifold.

An exemplary compounding method of controlling a compounding device to prepare an admixture of at least two distinct material sources can include examining material source solutions for incompatibility of the ingredients and operating a first and a second pump to prevent one of the incompatible source solutions from entering a common flow path. The processing method can detect degradation of a fluid line by evaluating one or more of calibration error rate data, cumulative volumetric flow data, or cumulative pump operation data. The processing method can also selectively transfer a first group of source solutions using the first pump, receiving pump data from one or more sensors that sense actions of the pumps, applying fluid correction factors and calculating discrete pump movements, the pump movements being indicative of an amount of source solution displacement by a pump, and operating the pumps to selectively dispense the source solution amounts according to a preparation order.

An exemplary pharmaceutical compounding system and device for mixing materials from at least two distinct material sources can include a transfer set and junction structure that has a junction body, a first inlet port located at a first portion of the junction body, a second inlet port located at a second portion of the junction body, and an outlet port located at a third portion of the junction body. The junction structure can be configured to mix fluid received from both the first inlet port and second inlet port and to deliver the fluid to the outlet port. The junction structure can also include attachment structure located on the junction body and configured to attach the junction structure to the housing of the compounding device at a location downstream of a pump system.

A mixing system for a power washer includes an electrically actuated valve communicated with a supply of a working fluid, and having a valve head that is movable between open and closed positions to control the flow rate of the working fluid through an outlet of the valve. The outlet of the valve is communicated with a fluid passage of the power washer to enable flow of the working fluid into a primary fluid and discharge of a mixture of the primary fluid and working fluid from the power washer when the valve is open, and to provide a flow of primary fluid from the power washer when the valve is closed.

Disclosed is a gradient proportioning valve for liquid chromatography that includes a plurality of inlet ports configured to receive a plurality of fluids, a manifold connected to each of the plurality of inlet ports configured to mix the plurality of fluids in a controlled manner to provide a fluid composition, the manifold including a plurality of conduits internal to the manifold, each of the plurality of conduits receiving fluid through a respective one of the plurality of inlet ports, an actuation mechanism having a piston located within a bored structure surrounding the piston, the actuation mechanism configured to open and close at least one of the plurality of conduits in a controlled manner where the piston and the bored structure have a tight tolerance configured to create a fluid tight seal, and a common outlet port configured to receive the fluid composition.

Processes for processing bio-sourced oil to produce bio-sourced oil dielectric fluids can be carried out using an apparatus mounted on a mobile transport platform system having a total footprint of no more than about 30 m.sup.2. The processes use a described array of pumps, heaters, filters, a degasser and vacuum system, and an additive metering/mixing valve system to achieve production under low energy and pressure conditions.
