Abstract: The disclosure relates to an arrangement in a valve for high-pressure gas cylinders, primarily for oxygen gas cylinders, in order, during the opening phase, to prevent gas-rush through the valve, the valve comprising an inlet connection (1) intended to be screwed into the gas cylinder and including an inlet passage (3) for the gas. A tubular sleeve member (6) is disposed in the gas passage and is axially movable along a predetermined distance. When the valve is closed, the one end of the sleeve member (6) abuts against the movable sealing member (5) of the valve, and its other end abuts against spring means (10) disposed in the gas passage. The sleeve member (6) is of such diameter that a gap (16) is obtained between the sleeve and the gas passage wall, the sleeve (6), in the initial phase of the opening movement of the valve, abutting against the movable sealing member (5) along the above-mentioned distance, such that a slight volume of gas flows through the gap, and, on further opening movement, the movable sealing member departs from the sleeve (6) and full gas flow is obtained through the valve.

Abstract: A connecting element is provided for connecting together adjacent shuttering panels of the kind in which reinforcement strips with rows of holes provided therein are arranged at the edges of the shuttering panels and are dipsosed perpendicular thereto. The connecting element consists essentially of a curved lever arm (13) which tapers from a spigot part (17) to an end surface (18). The spigot part (17) adjoins a handle portion of the connecting element at a flange (16') defining an abutment edge (16). The handle portion is curved in essentially U-shaped manner and has a support surface (20) at the inside of its limb connected to the spigot portion (17). In operation the engagement end (18) of the lever arm is first introduced through two aligned holes in the adjacent reinforcement strips of two adjacent shuttering panels and the connecting element is then rotated about the abutment edge (16) so as to cause the spigot part (17) to enter into the two aligned bores. During this the lever arm clamps the two reinforcement strips together. In the engaged position shown in FIG. 2 the support surface (20) contacts one side of one of the connecting strips and the engagement surface (18) contacts the opposite side of the other reinforcement strip. The U-shaped handle of the connecting element has been pivoted downwardly so that the abutment end (12') thereof engages against the same side of the reinforcement strip (15') as the engagement surface (18). In this position the connecting element is reliably locked in place and the shuttering panels are reliably connected together.
