An insert for an engine block and systems, assemblies, components, and methods thereof can comprise a ring-shaped body having an inner surface and an outer surface opposite the inner surface. The inner surface can having one or more sealing grooves adapted to receive and retain respective sealing rings. A maximum outer diameter of the ring-shaped body can be defined by the outer surface and can be greater than a height of the ring-shaped body in a longitudinal direction of the ring-shaped body.

The present disclosure relates to an aerosol delivery device that includes a reservoir housing that defines a mouthpiece channel. The aerosol delivery device includes a sealing member configured to be received within the reservoir housing to define a reservoir chamber configured to retain an aerosol precursor composition therein. The aerosol delivery device also includes a substrate member that is configured to be received within the reservoir housing and to be directly engaged with a vaporizing assembly for forming an aerosol. The reservoir housing, sealing member, substrate member, and/or vaporizing assembly can be used for forming aerosols with precise and reproducible compositions.

Electronic cigarettes may include an electronic cigarette, and a replaceable vaporizer assembly. Electronic cigarette may include an electronic cigarette body, and a replaceable vaporizer assembly. In certain embodiments, the electronic cigarette body may include a mouthpiece, an E-liquid storage tank, an E-liquid refill cap, a mounting ring, a connector, and a vaporizer mounting base having an internal thread. The replaceable vaporizer assembly may include an external thread of a vaporizer assembly base. The replaceable vaporizer assembly may be replaced by removing the mouthpiece, unscrewing the replaceable vaporizer assembly to detach the external thread of the vaporizer assembly base from the internal thread of the vaporizer mounting base, pulling up the replaceable vaporizer assembly, replacing a new replaceable vaporizer assembly, and reinstalling the mouthpiece back in place. The electronic cigarette includes a top adjustable air intake. The mouthpiece may be used to adjust the air intake by rotating the mouthpiece.

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.

A sealing apparatus includes a moveable seal holder with a cavity and includes a seal assembly disposed at least partially in the cavity. The seal assembly includes a resilient seal member including a fluid-facing end with a fluid-facing end surface, and the seal assembly includes an actuator plate configured to reciprocate between a first and a second position relative to the protective plate. The first actuator plate includes a fluid-facing end surface and a first camming surface. The seal assembly further includes a first protective plate disposed between the seal member and the first actuator plate. The actuator plate is configured to compress the seal member and to move the fluid-facing end surface of the seal member outward from a resting position when the actuator plate is in the second position.

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.

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 sufficient sealing property of a through hole is ensured. A sealing structure includes a cylindrically-shaped body part inserted into the through hole, formed of a thin plate of a first thickness, one end of the body part being open and another end of the body part being closed, a tapered part connected to the opened one end of the body part and including a diameter gradually expanding outward as a distance from the body part increases, and a first bent part connected to the tapered part, formed of a thin plate thinner than the first thickness, and bent inward so that a protruding part protruding outward elastically abuts against an inner peripheral surface of the through hole.

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.
