A method of charging a hollow valve with metallic sodium includes providing a workpiece, as a semi-finished product for a hollow poppet valve, in which a cavity has an upward opening at a free end of a valve stem at a working position; inserting a nozzle into the opening to feed an initial inert gas into the cavity by jetting the inert gas from the nozzle; moving up the nozzle to put a holder between the workpiece and the nozzle, the holder holding a rod-like metallic sodium; and inserting the nozzle into a first end of the holder while an additional inert gas is jetted into the cavity from the nozzle to push down the rod-like metallic sodium along with the inert gas from a second end of the holder into the cavity of the workpiece.

A heated throttle valve apparatus is disclosed herein, which includes a valve system with a valve driver configured to provide a rotational force to a valve assembly via a thermal isolating drive coupler configured to prevent the transfer of thermal energy from the valve assembly to the valve driver. The valve assembly includes a valve body and a valve closure member, a valve shaft with a valve shaft heater in a first heating zone and one or more body heaters in a second heating zone, permitting the user to control temperature in the heating zones independently. An electrical conductor strain relief is provided, configured to eliminate strain in the shaft heater electrical conductors when the valve closure member undergoes a change in angular orientation. The electrical conductor strain relief includes a curvilinear flexible member wound between a first connection area and a second connection area.

A hollow valve having optimized interior stem geometry, whose valve stem has surface-enlarging structuring on an inner surface is provided. Also provided is a method for manufacturing a valve body of such a hollow valve, wherein the method comprises: providing a bowl-shaped semi-finished product having an annular wall that surrounds a cavity, and having a base section, followed by lengthening the wall with an inserted, structured mandrel, and lastly, reducing an outer diameter of the annular wall without a mandrel to obtain a predetermined valve stem outer diameter of a valve to be manufactured.

A fluid control apparatus includes: a base plate; and a gas line installed on the base plate. The gas line includes a resin member provided in a predetermined direction on the base plate, a first bracket provided on the resin member, a plurality of joints provided on the first bracket, a plurality of fluid control devices provided to the plurality of joints, and a heater mounted to the plurality of joints and the plurality of fluid control devices. The first bracket includes a first fixing portion fixed to the resin member, a first leg portion extending from the first fixing portion in a direction of away from the base plate, and a first installation portion protruding from an end portion of the first leg portion on an opposite side to the first fixing portion to intersect with the first leg portion and on which the joints are installed.
