The primary sealing portion 11 is formed so as to be tapered from an axially inner end thereof toward an axially outer end thereof in an axial cross-sectional view, and has a flat surface 11c extending from a radially outer end 11b of the axially outer end thereof toward the radially inner side.

The present invention relates to a sealing member for a base station antenna and a base station antenna comprising the same as well as a method and device for manufacturing the sealing member. The sealing member (2) is flexible and resilient and is configured to form a seal between an open end (5) of a radome (3) and an end cap (1) of the base station antenna. The sealing member is an elongated sealing strip having two ends, wherein the two ends of the sealing member are lappable with each other, and the sealing member has a groove extending over its entire length, which groove is defined by two side limbs and a bottom limb connecting the two side limbs of the sealing member, wherein the groove is configured to engage with an edge of the open end (5) of the radome, and wherein the sealing member is configured to be received in an annular recess of the end cap (1) and isolate an interior of the radome (3) from the environment. The sealing member can be manufactured cheaply and can be flexibly applied to base station antennas with different sizes.

A multi-lobe seal for a sealing device for sealing an opening in a multi-layer wall of a fuel tank, the multi-layer wall having a layer of fuel barrier material and an opening in the multi-layer wall, the multi-lobe seal being fuel-impermeable and capable of being positioned in contact, at the opening in the multi-layer wall of the fuel tank, between the layer of fuel barrier material of the multi-layer wall of the fuel tank and a component, is disclosed. The multi-lobe seal includes, on the face capable of being in contact with the layer of fuel barrier material of the multi-layer wall, at least two protrusions, one of which leans on the layer of fuel barrier material of the multi-layer wall.

Apparatuses for controlling fluid flow are important components for delivering process fluids for semiconductor fabrication. These apparatuses for controlling fluid flow require a variety of fluid flow components which are tightly packaged within the apparatuses for controlling flow. Servicing the apparatuses requires specialized equipment and methods which enable installation of seals in close quarters in apparatuses which are installed in the field. Seal retainers may be used to retain the seals during assembly of fluid flow components into apparatus for controlling flow.

A sealing member is one used for a cylindrical lithium-ion battery. The sealing member is interposed between a bottom-closed cylindrical case and a cap, is made of perfluoropolymer, and has dimensions that meet the following relational expressions: when an axial distance from a cap upper surface to a leading end portion in a case is defined as HC, an axial distance from the cap upper surface to a leading end portion in the sealing member is defined as HG, a thickness of the sealing member is defined as TG, a value of TG divided by HG is defined as X (=TG/HG), and a value of HG divided by HC is defined as Y (=HG/HC),

Provided is a method for manufacturing a gasket member as described below. A plate-like base material is clamped between a first and a second split mold, and a gasket is fixed to a surface of the base material by injecting and filling a rubber-like elastic material into a cavity defined between the base material and the first split mold. An air vent is provided including an exhaust groove and an exhaust hole, the exhaust groove extending from the cavity toward an inner or outer peripheral side on a butting surface between the base material and the first split mold and partially opening in a circumferential direction of the cavity, the exhaust hole extending from the exhaust groove in a clamping direction of the first and second split molds. Air in the cavity is discharged through the air vent when the rubber-like elastic material is injected and filled into the cavity.

An EGR valve device including a housing including a flow passage, a valve element that opens and closes the flow passage, a valve shaft to which the valve element is provided, and an outer housing including an assembly hole for the housing and other flow passages.
