Abstract: A valve assembly includes a first part mountable to a fluid port of a panel and having a first opening for ingress of fluid into the first part from a first side of the panel, and a second opening for egress of fluid out of the first part through the fluid port to a second side of the panel; a second part within the first part for sealing the second opening when in a first position, a deformable member, and a resilient member biased to move the second part to a second position, to provide a fluid flow path from the first opening to the second. In an initial state, the deformable member retains the second part in the first position. Upon contacting liquid within the first part, at least part of the deformable member deforms to enable the resilient member to move the second part to the second position.

Abstract: A fastener includes a base member; a first member, on the base member and having a through bore; a second member, on the base member and spaced from the first member to form a receiving portion to receive a panel structure, including an aperture defining an internal surface, the internal surface including at least one stop member protruding radially inwardly, and a nut member, coaxially aligned within and frangibly connected to the internal surface, including at least one block member protruding radially outward from an outer surface of the nut member to stoppingly engage with the at least one stop member. During use, the nut member moves from a first position, where the nut is frangibly connected to the internal surface, to a second position, where the least one block member abuttingly engages with the at last one stop member.

Abstract: The affixing device for pieces includes an affixing element (1) that can be positioned through an opening (6) in each one of the pieces (7, 8) that are affixed to each other, that also comprises a first and second retaining elements (2, 3), which, when they are in their affixing positions, are in contact with the pieces (7, 8) that are affixed to each other, with the affixing element (1) passing through the first and second retaining elements (2, 3), and with the first retaining element (2) including an accommodation space for a tool. This configuration allows for faster and simpler assembly of the affixing device, also avoiding problems of misalignment.
