Abstract

1305942 Rolling diaphragm pneumatic springs JONAS WOODHEAD Ltd 8 April 1970 16675/70 Heading F2S In a rolling diaphragm pneumatic spring, at least one edge of the diaphragm 29 is attached to its respective reciprocating member i.e. cup 23, 24 or plunger 4 by jamming a parallelsided part of the diaphragm adjacent the edge between a pair of parallel conical surfaces, 34 or 36 (formed on a ring 31 or 32 separate from the plunger or cup) and 33 or 26 (formed on the plunger or cup). As shown and in Fig. 2 (not shown) one surface at each edge is constituted by a free ring 31, 32 (44) whereas in Fig. 3 (not shown) at one edge one of the conical surfaces is constituted by a ring 63 moulded into the diaphragm 61. The diaphragm may have a thickened rim at either edge.
