The invention concerns an absorbent article, such as a diaper, pant diaper, incontinence guard, panty liner, open diaper, belt diaper or the like. More specifically, the invention concerns a fastening device for an absorbent article having a receiving portion with an opening, and a tab element which is shaped so that it can be inserted into the opening of the receiving portion upon closing the article. It is characteristic of the invention that both the tab element and the receiving portion have fastening means. By the fact that both the receiving portion and the tab element have fastening means, a strong and stable connection is formed between the components of the fastening device.

The invention relates to a tobacco alkaloid patch (10; 41; 42; 43; 51; 52; 53; 54) for transdermal administration of a tobacco alkaloid, said patch comprising an impermeable backing (11) and a membrane (14) which defines a reservoir (12) there between, said membrane being permeable to and in contact with said tobacco alkaloid, said tobacco alkaloid being mixed with a viscous flowable gel, said impermeable backing and said membrane being at least partly joined by a sealing and wherein the amount of said tobacco alkaloid is above 10 mg.

The invention relates to a pressure vessel. In order to improve sealing properties, the present invention provides a pressure vessel comprising: a boss part which is arranged in a cylindrical shape and has a through-hole formed in the center part thereof in the vertical direction, and a boss flange part; the boss flange part is integrally expanded towards the outer side of the radius direction along the circumferential direction at the lower part of the boss extension part, and extends the through hole in the vertical direction at the inner side of the radius direction; a liner part which is configured in a container type, has an accommodation space communicating with the through hole, accommodates a fluid therein, and has an upper part which is insert-molded along a lower surface of the boss flange part so as to be sealed and coupled to the lower surface of the boss flange part; and the sealing part is combined with a boundary area between the lower part of the boss flange part and the upper part of the lining part in a sealing manner so as to prevent the fluid accommodated in the accommodating space from leaking.

The invention relates to a gas pressure regulator (1) for regulating the pressure of a gaseous fuel, said gas pressure regulator having a housing (2) in which a gas piston (3) movable longitudinally is arranged ), the gas piston delimits a gas chamber (5) and delimits a pressure chamber (7) that can be filled with a working fluid, wherein the gas piston (3) has a first seal (24) surrounding its outer side, The gas piston (3) is guided sealingly on the housing (2) by means of the first seal and the first seal seals the gas chamber (5). The cooperation of the gas piston (3) and the valve seat (21) forms an overflow valve (20), via which gas can be led out of the gas chamber (5). A second circumferential seal (25) is formed on the outside of the gas piston (3), by means of which the gas piston (3) is likewise guided in a sealing manner in the housing (2) , wherein the gas piston (3) is at least partially surrounded by a low-pressure gas chamber (9), and the second seal (25) separates the low-pressure gas chamber (9) from the gas return chamber (10) , wherein the gas chamber (5) can be connected to the gas return chamber (10) through the overflow valve (20). The invention also relates to a system for supplying an internal combustion engine with gaseous fuel, the system having an intermediate tank (200) and such a gas pressure regulator (1). Furthermore, in a method for operating the system there is a return accumulator ( 300 ), the pressure of which is set between the pressure in the gas chamber ( 5 ) and the pressure in the gas tank ( 100 ).

A scroll compressor includes a housing, a fixed scroll, and a movable scroll. A compression chamber is formed between the movable scroll and the fixed scroll. An opposing wall is located in and fixed to the housing. A back pressure region is formed between the opposing wall and the movable scroll, and a back pressure in the back pressure region urges the movable scroll toward the fixed scroll. An annular sealing member is arranged between the movable scroll and the opposing wall. The movable scroll includes a holding portion that holds the sealing member. The sealing member includes a rubber portion, which elastically deforms in the holding portion, and a resin portion, which is made of a material harder than the rubber portion. The resin portion at least partially projects out of the holding portion toward the opposing wall. The resin portion is in contact with the opposing wall.

A subassembly for a high pressure fuel injector control valve, comprising a control valve member and a sleeve attached to a stem of the control valve member, the sleeve extending along at least a partial axial length of the stem of the control valve member, and wherein a clearance, provided between the sleeve and the control valve member, is in fluid communication with the control chamber such that during use, pressure compensation occurs, as the sleeve is caused to expand and seal against the control valve bore, thereby preventing leakage of fuel within the control valve assembly.
