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.

A water jet condenser with multiple closed water chambers and a jet flow adjusting valve used in a sugar refinery. A water chamber of the condenser is divided into an open large water chamber (6) and a plurality of closed small water chambers (14); each water chamber is respectively provided with a jet nozzle (3) and a spray nozzle (7); the plurality of closed small water chambers (14) are respectively controlled by a plurality of pneumatic or electric butterfly valves (4); the lower part of the condenser body (13) is provided with a single-layer or multi-layer jet flow regulating valve (2) for keeping the concentric change of the diameter of the central round aperture of a jet flow passage; the jet nozzle (3) and the spray nozzle (7) in each water chamber are respectively cooperated with the single-layer or multi-layer jet flow regulating valve (2).

Embodiments described herein relate to a valve for semiconductor processing. The valve includes a valve body having an inlet conduit and an outlet conduit separated by a diaphragm body. The diaphragm body includes a motor, a transmission link coupled to the motor, a rotatable ring surrounding a fixed plate and separated by a dynamic seal, the rotatable ring coupled to the transmission link, and one or more shutter plates movably coupled to the rotatable ring by a respective pivotable fastener, wherein the fixed plate includes an opening and the one or more shutter plates are movable relative to the opening.

An air spring for a heavy-duty vehicle includes a bellows chamber, a piston chamber, and at least one opening. The piston chamber is operatively connected to the bellows chamber. The at least one opening is in fluid communication with the bellows chamber and the piston chamber to provide fluid communication between the bellows chamber and the piston chamber. An orifice assembly is disposed adjacent the at least one opening for variably changing the size of the opening. The air spring provides damping to the heavy-duty vehicle.

The present invention includes a lateral support member for a server computer constructed to permit advantageous airflow. The present invention can be operated to shunt organized airflow into multiple computer cases and/or organized airflow from multiple computer cases to a dedicated heat reservoir.

A dryer assembly for a vehicle wash system for emitting high velocity air onto a vehicle exterior includes a housing having an air inlet and an outlet. The air inlet is in communication with a motor assembly having an operating and a non-operating mode. The assembly also includes a gate mechanism in communication with the air inlet. The gate mechanism includes a plurality of pedals that are each pivotable between a first position and a second position. The gate mechanism is in communication with a controller, which directs movement of the plurality of pedals from the first position where the plurality of pedals surround the inlet opening such that air can flow into the housing and the second position where each of the plurality of pedals covers a portion of the inlet opening such that in their entirety the plurality of pedals obstruct the inlet opening to prevent air for flowing into the housing.
