    摘要: A valve for closing a gas container includes a valve body with a continuous longitudinal bore along a longitudinal axis and a displaceably-guided valve tappet mounted therein. The valve body extends longitudinally parallel to the axis from a connection region with a connection-side end face to a fastening region with a gas-container-side end face having a smaller diameter than the connection region. The connection region has a stop face that stops a gas container base-body head when the fastening region has been inserted into an opening in the head. The valve body laterally has a double groove in the fastening region that includes two grooves that follow one another longitudinally and that a sealing lug facing away from the longitudinal axis separates to allow the head to be pressed gas-tightly with the fastening region in the double groove region when the fastening region is introduced into the head.

    摘要: High-pressure cylinder having an internal core in plastic material and a surface covering having one or more layers of composite material, partially incorporating a nozzle in metal material attached to the upper end portion of the neck of the core shaped to receive at least one accessory, such as a tap or a valve, the nozzle being composed of an internal element and an external element which can be screwed one to the other to clamp on the neck, wherein the neck has a slight narrowing of diameter starting from its mouth, such as to determine an internal conical surface suitable for coupling with a corresponding external conical surface of the internal element of the nozzle, and an external conical surface suitable for coupling with a corresponding internal conical surface of a modular ring in plastic or elastomeric material interposed between the neck and the external element of the nozzle.

    摘要: A structure whereby a piping nozzle can be simply attached to a tank body is disclosed. A cylinder of a nozzle body is inserted through the interior and exterior of the tank body via a nozzle body insertion hole in the tank body. A skirt is provided on an end portion of the cylinder, and expands annularly from the end portion of the cylinder in the interior of the tank body. A sealing member is interposed between an inner surface of the tank body and the skirt around the nozzle body insertion hole. A spacer member is disposed on an outer surface of the tank body around the cylinder. By tightening a nut on a male screw of the cylinder of the nozzle body, a portion of the tank body around the nozzle body insertion hole is sandwiched by the skirt of the nozzle body and the spacer member.
