An electronic cigarette vaporizer comprises a hollow vaporizer housing and a vaporizing device sleeved inside the vaporizer housing; wherein the vaporizer housing has a mouthpiece end and an opening end arranged with a connecting device for connection with the battery component, a mouthpiece is arranged in a center of the mouthpiece end, a vapor outlet tube extending in an inward direction from the mouthpiece to a middle portion of the vaporizer housing is arranged; wherein the vaporizing device is disposed in the vaporizer housing at one side where the opening end is formed, and comprises a vapor tube sleeve, a throttle lid, a heating unit, a vaporizing base and an electrode lid, which are arranged in turn towards the outer side from the inner side, and the throttle lid is provided with throttle orifices for directly communicating the liquid storage chamber and the end portions of the liquid guiding strip.

A seal is disclosed for a wing for providing an aerodynamic seal between a fixed aerofoil and a movable control surface.

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 sealing device seals a first component part of a lithography apparatus vis-à-vis a multiplicity of second component parts of the lithography apparatus. The sealing device includes a multiplicity of sealing rings and a multiplicity of connection locations. The sealing rings are connected to one another with the aid of the connection locations.

An apparatus for connecting two pipes in fluid communication includes a connector body having opposing open ends, with each open end configured for receiving a free end of a pipe, and a mechanical interlock arrangement for preventing or limiting axial movement of the connector body relative to a free end of a pipe when the free end of the pipe is received in an open end of the connector body. A mechanical seal arrangement provides a metal-to-metal seal between a pipe inserted into one of the open ends and the connector body.

An aerosol generation device includes a case into which a cigarette is to be inserted; a protrusion pipe of a hollow shape protruding from one end portion of the case and having an opening; a heater installed in the case such that an end portion thereof is positioned inside the protrusion pipe, and configured to generate heat when an electric signal is applied thereto; and a heater fixing portion installed inside the protrusion pipe to support the heater and comprising a round surface that extends from an inner side surface of the protrusion pipe.

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.

An arrangement of a sensor in a holding device, the holding device having a passage opening and the sensor having a process connection at least partially inside the passage device, which achieves a reliable seal between the sensor and the holding device, wherein the holding device has an internal taper in a sub-region of the passage opening and the process connection has an external taper in a sub-region, which is constructed in a manner corresponding to the internal taper of the holding device and comes to bear against the same, wherein the external taper has a first section and a second section, wherein the first section and the second section are constructed from different materials.

An aerosol-generating system includes a main body, a cartridge, and a connecting component. The main body includes a main body housing enclosing a power supply. The cartridge includes a cartridge housing enclosing a reservoir of liquid aerosol-forming substrate. The cartridge is releasably connectable to the main body by the connecting component. The connecting component is fixed to the main body housing and is less stiff in at least one direction than the main body housing. The connecting component that is less stiff the main body housing and the cartridge housing can act as a shock absorber when the aerosol-generating system experiences a significant impact, such as when dropped on a surface. This reduces damage to other components of the system and, in particular, may prevent leaks of liquid resulting from damage to the liquid reservoir.

Gas distribution assemblies and process chambers 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 also described.
