An exemplary embodiment of the present disclosure relates to a motor-integrated intake apparatus, and the motor-integrated intake apparatus includes: a flow path which is formed in an annular shape in a circular housing; an inlet unit which is installed at one side of the housing and guides a flow of a fluid into the flow path; a discharge unit which is installed at the other side of the housing and guides a discharge of the fluid which is introduced into the inlet unit and passes through the flow path; a piston unit which is made of a magnetic material and compresses the fluid, which is introduced through the inlet unit, while rotating along the flow path; and a coil unit which is installed on the housing and provides rotational power to the piston unit by forming a magnetic field.

An adjustable orifice valve system is disclosed which comprises an iris valve to control flow rate through the system, and a slide valve to prevent leaks through the system. Both valves can be adjusted through a gear train manually via a handle and/or automatically via a motor. When the iris valve is in a minimally open configuration, the gear train engages the slide valve to permit or disallow flow through the slide valve. When the iris valve is in a partially or maximally open configuration, an opening in the slide valve is aligned with the flow axis of the system to permit uninhibited flow through the slide valve. The position of the handle can indicate aperture size of the iris valve and/or position of the slide valve. In some embodiments, a pressure transducer and/or gear position sensor can provide determination of flow rate through the valve system.

An additive manufacturing system can include a powder dispenser; a gate adjacent to the powder dispenser; a recoater blade system; and a control operable to move the gate with respect to the powder dispenser to selectively dispense powder from the powder dispenser.

A compressed air conduit can have a cross-sectional area, and a valve, the valve having at least one arm being deployable laterally into the cross-sectional area of the conduit to restrict flow within the conduit.

A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. The inlet-adjustment mechanism includes a plurality of blades disposed about the air inlet and each pivotable about one end of the blade, the blades extending through a slot in the air inlet wall when the blades are in the closed position so as to form an orifice of reduced diameter relative to a nominal diameter of the inlet. Movement of the inlet-adjustment mechanism from the open position to the closed position is effective to shift the compressor's surge line to lower flow rates.

A radial compressor has an iris diaphragm mechanism for a pressure-charging device of an internal combustion engine. The radial compressor has a bearing assembly, in which a rotor shaft is rotatably mounted, having a compressor impeller arranged in a compressor housing for conjoint rotation on the rotor shaft and having a fresh air supply channel for carrying a fresh air mass flow to the compressor impeller. The iris diaphragm mechanism is upstream of the compressor impeller, allowing variable adjustment of a flow cross section for the fresh air mass flow for admission to the compressor impeller, at least over a partial region. For this purpose, the iris diaphragm mechanism has multiple lamellae which each have a plate style lamella main body and a pin style actuating element as integral constituent parts of the respective lamella.

Disclosed is system, method, and rack stand portion for the advantageous cooling of computer equipment 305. The rack stand 200 includes a hollow body 210, 212 that may be formed of cartridges 2416. Gas from an airflow source 5204 is guided into the rack stand body and then into a sealed case of the computer equipment. Air flow is then guided out of the computer equipment for recirculation, exhaust, or other purpose.

An inlet valve that includes a pipe and a housing that forms a chamber around this pipe, in which an aperture is affixed with blades that are slidingly provided in the housing. Whereby these blades present a protruding section with edges that lie against one another and whereby the blades are provided with a spindle and there are means to enable the blades to pivot around these spindles, during the movement of the spindles, between a closed position, whereby the sections are oriented radially to close off the passage in the pipe, and an open position whereby the sections are turned away from the pipe.
