Gas distribution assemblies and process chamber comprising gas distribution assemblies are described. The gas distribution assembly includes a gas distribution plate, a lid and a primary O-ring. The primary O-ring is positioned between a purge channel of a first contact surface of the gas distribution plate and a second contact surface. Methods of sealing a process chamber using the disclosed gas distribution assemblies are described.

Embodiments of a high-pressure, high power, reciprocating positive displacement fluid pumping system and methods are included. The system may include a high-pressure, high power, reciprocating positive displacement pump including a pump plunger, a fluid end block assembly, and a fluid cover. The fluid end block assembly may include a fluid end block body, a suction port, a discharge port, a pump bore positioned in and extending through the fluid end block body, and a fluid chamber positioned in the fluid end block body and in fluid communication with each of the suction port, the discharge port, and the pump bore. The fluid chamber has an open end portion, and the pump plunger may be positioned to move in the pump bore to pressurize one or more fluids in the fluid chamber. The fluid cover includes a monolithic body having a first portion and a second portion, the first portion being received in the open end portion and sealably engaged with the fluid end block body, the second portion being mechanically connected to the fluid end block body.

Disclosed is a seal for an engine firewall. The seal including a proximal part having a recess; a distal part having a notch; and a flexible intermediate part integrally extending between the proximal part and the distal part.

This sealing device for a railway, the railway including a housing extending between a side face of a rail and a side wall of a slot reserved in the ground for housing said rail, is characterized in that it is a sealing device inserted in the housing and fixed in the housing by a suitable putty, and in that it is a resiliently deformable profile, to be able to be inserted under stress in the housing and to be pressed against the side face of the rail and the side wall of the slot.

The object of the invention is a seal (10) for an inlet opening (120) of a latch (100), in particular a motor vehicle latch, having at least a partially flexible sealing element (11) with at least an insertion slot (12), whereby a first seal wing (11.1) and a second seal wing (11.2) are formed on the sealing element (11), whereby a striker can at least be partially arranged in the inlet slot (11).

A seal arrangement is provided for sealing an exposed edge of a composite laminate part having a fay surface configured to be joined to a structure. The seal arrangement includes a precured edge seal covering the exposed edge and a cover covering the edge seal. A seal bead located within a recess in the fay surface of the part forms a seal between the part and the structure.

An atomizer includes a main body defining an airflow channel and a liquid storage cavity isolated from each other and an atomizing element. The atomizing element includes a porous body and a porous heating film. The porous body includes an atomizing surface and a liquid absorption surface. The atomizing surface is a plane and is substantially parallel to a direction of an air flow in the airflow channel, and the porous heating film is formed on the atomizing surface. The liquid absorption surface can absorb a liquid in the liquid storage cavity.

An aerosol generation device may include a first housing comprising an opening at one side, an inner space for accommodating a cigarette inserted through the opening, and a heater disposed in the inner space; a second housing coupled to other side of the first housing and including a controller; a fastening portion configured to couple the first housing to the second housing; a battery coupled to the second housing; and a case coupled to the second housing for accommodating the second housing, the fastening portion, and the battery therein, wherein the fastening portion is prevented, by the case, from being exposed to outside.

A fitting apparatus for connecting pipes according to the present invention includes a fitting unit which includes a first body into which a first pipe is inserted and a second body which is connected to the first body to form a pipe insertion space therein together with the first body and into which a second pipe is inserted, wherein in the first body and the second body, a first recessed groove and a second recessed groove spaced apart inward from the first recessed groove are formed along an inner circumferential surface thereof, respectively, a compression member which is provided in the first recessed groove to compress and fix the first pipe or the second pipe, and a sealing member which is provided in the second recessed groove to maintain airtightness between the fitting unit and the first pipe or between the fitting unit and the second pipe.

A valve and associated components and methods, and a container including such a valve. The valve can include a flow guide to guide flow of material away from a sealing engagement between sealing members of the valve. The flow guide assists in preventing ingress of material between the sealing members to maintain proper function of the valve.
