Apparatus and method contemplating a high pressure fluid end assembly having a body defining a body bore and defining a recess in the body intersecting the body bore. A closure is joined to the body and forms a sealing surface. A seal is mounted to the body in the recess and configured to extend from the recess beyond the body bore to seal against the sealing surface formed by the closure.

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.

An assembly comprises

circular panel an annular body; and an elastomer.

The annular body has a panel seat surrounded by a lateral surface having a ring shaped, surrounding, outer groove bounded in a first axial direction by a first outer shoulder and bounded in an opposing, second axial direction by a second outer shoulder.

Adjoining the first outer shoulder is a guide surface having a radius monotonically increasing with separation from the first shoulder.

The circular panel has an outer lateral surface having a peripheral inner groove extending radially inwards.

The two inner shoulders have a convex contour in which the rotational axis of the circular panel extends.

The elastomer ring is clamped between both inner shoulders and both outer shoulders, whereby a shifting of the circular panel out of the annular body is prevented up to a limit loading.

A culture apparatus includes an inner box for housing a culture, an outer box surrounding the inner box, and a first vibration prevention mechanism that is disposed between the inner box and the outer box, and is configured to prevent the inner box from vibrating due to the vibration of the outer box.

A sealing structure of a humidifier includes a main structure, a left end cover, and a right end cover. The left end cover and the right end cover are arranged on left and right end faces of the main structure, respectively. A dry air inlet tube is connected to a top end face of the left end cover, and a dry air outlet tube is connected to a top end face of the right end cover. A wet air outlet tube and a wet air inlet tube are connected to left and right sides of a top end face of the main structure, respectively. Membrane tubes are arranged on an inner side of the main structure. Potting resin layers are arranged on both ends of the membrane tubes. High-temperature resistant sealant layers are arranged at connecting portions between each end cover and the main structure.

Provided is an annular gasket for sealing a gap between opposed surfaces of two members, the gasket including a core body including a plurality of split components, a sealing unit fixed to the core body, and an elastic member, in which: ends of the plurality of split components are mated together in such a manner as to have a gap between the ends; the ends mated together are joined by the elastic member; and edges of the joined ends are inclined relative to a longitudinal direction of the split components in plan view.

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 hydraulic end assembly structure of a plunger pump, comprising a valve housing assembly, a suction gland and a suction pressing cap. The suction gland is connected to the suction pressing cap, and the suction gland is connected to the valve housing assembly through the suction packing seal assembly.

The present disclosure provides a sealing apparatus for use in a hypertube, which includes a first tube, a second tube having one end connected to an end of the first tube, and a gasket including a seal made of a fiber structure formed with a space that is filled with a sealing fluid, wherein the gasket is configured to seal a space between the first tube and the second tube.
