Abstract:
With a device (1) for equalizing pressure surges in cases of possible dust or gas explosions in closed systems, such as silos, pipelines or the like, comprising a hinged cover (3) which can be pivoted on an outlet connection or a closing edge (2) and has a smooth outer surface (12) and comprising a deflecting plate (8) on the outlet connection or on the closing edge (2) for the cover (3) to strike against in the event of an explosion, it is intended to achieve not only cost-effective production but also in particular a significant weight saving of the hinged cover, quick changing of the cover in the case of damage, or quick fitting of the cover in the first instance, and an improvement in the protective effect of the system. This is achieved by the hinged cover (3) being made of a carbon/glass-fibre material, whereby the main lid body (3a) is formed from carbon/glass fiber mats (18, 19) that form the outer walls (12, 13), with an enclosed body (14) made of plastic, such as foam material, for example, forming the lid contour.

PROBLEM TO BE SOLVED: To provide a venting device which can be inserted into openings of enclosures with different wall thicknesses.SOLUTION: A venting device includes a body with an insertion portion for insertion into an opening of an enclosure and a head portion. The body has a passageway that extends through the insertion portion and the head portion for passage of a fluid from the enclosure to the ambient environment. The venting device further includes an air permeable, water impermeable venting element covering the passageway. An engagement section being arranged circumferentially about the insertion portion for engagement with the wall of the enclosure is radially deformable and specifically permitting insertion of the venting device into openings of enclosures with different wall thicknesses.

PROBLEM TO BE SOLVED: To assure a safety characteristic at the time of removing a cover by a method wherein a safety device enables a fastening ring to be removed only when a discharging valve is open. SOLUTION: This container 1 is provided with a fastening ring 5 for fixing a cover 3 to the container 1 and sealing its opening 4. The cover 3 has a discharging valve 7 and a safety device 10. The discharging valve 7 protrudes out of the cover 3. The safety device 10 is engaged with the fastening ring 5 by an engagement unit 11 in such a way that the fastening ring 5 can be removed only when the discharging valve 7 is open. The safety device 10 has a first part 10b extending along the discharging valve 7 and a second part 10a extending from the first part 10b to the engagement unit 11. The cover 3 has the discharging valve 7 and the safety device 10. The safety device 10 is engaged with the fastening ring 5 in such a way that the removal of the fastening ring 5 is attained only when the discharging valve 7 is open. The safety device 10 is completely removed from the discharging valve 7. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel system not susceptible to mechanical failure and including an fuel tank low in manufacturing cost. SOLUTION: The fuel system comprises: the fuel tank in which fuel is stored; at least a vent line disposed in the fuel tank and having an inlet opening disposed at an upper side area of the fuel tank and the other end disposed to an opposite side of the inlet opening; and a liquid separator. The liquid separator communicates to the other end of the vent line and communicates to the evaporator canister, and fuel vapor flowing into the inlet opening flows into the vapor canister through the liquid separator.

Abstract:
PROBLEM TO BE SOLVED: To further improve the known venting devices such that any leakage points within the venting device are reliably sealed against penetrating media of any type, except against air exchange.SOLUTION: The invention relates to a venting device, particularly for fluid-storing reservoirs such as tanks, comprising a connecting part 10 for establishing an air-conducting and/or fluid-conducting connection 14 to the inside of the reservoir and comprising a closing part 16, which can be removed from the connecting part 10. When the closure cap is fastened, at least one leakage point 18 in the form of an air exchange opening exists between the closure cap and the connecting part 10. A labyrinth-like seal 20 effectively seals the respective leakage point at least against penetrating media such as water and/or surfactant chemicals, but not against air exchange for actual venting.
