    Abstract: A method for manufacturing an inflatable cushion of utility as a jack. The cushion is made from a piece of fabric coated with elastomer and comprising a polygonal bottom wall and a top wall which includes triangular portions between which are circumferentially interposed gores. The top wall is formed by folding over the triangular portions onto the bottom wall and securing the gores to the triangular portions, as by an adhesive or vulcanization. If desired, a reinforcing and retaining disc can be secured to the outer and/or inner face of the upper wall. A center inflating valve may be secured to the center of the upper wall.

    Abstract: A closing device for a pneumatic system comprising an inflatable bag having a closing face co-operable with an annular seat defining an aperture which is connected to the pneumatic system by passage means. The bag has an orifice which conduit means puts in communication with the interior of the passage means so that pressure variations in the passage means inflate or deflate the bag so that the closing face closes or unmasks the annular seat. The bag consists of two fluidtight sheets interconnected along their peripheries and means are provided inside the bag to ensure that the two sheets are always spaced apart in the region of the orifice. The device can be employed in combination with the inlet of fluid-flow generating means to control the fluid flow through the inlet.
