Abstract

1,211,242. Reciprocating pumps and compressors. M. PEQUIGNOT. Nov. 3, 1967 [Dec.19, 1966], No. 50161/67. Headings F1A and F1N. [Also in Divisions A5, F2 and G1J A diaphragm comprises a plurality of interconnecting tubular elements of non-circular section disposed contiguously and laterally secured together in side by side relationship, the elements being adapted to be connected to a source of fluid to cause deflection of the diaphragm by deformation of the cross-section of the elements. The elements may be concentric rings or coils of a spiral and the diaphragm may be initially flat or bowed or may be in the form of a tubular bellows. In one embodiment suitable for use as an artificial heart the elements are longitudinally arranged to form a pocket which is divided into two parts by a longitudinal partition.
