Abstract

1,039,145. Diaphragm pumps and compressors. DECCA Ltd. July 28, 1965 [April 28, 1964], No. 17610/64. Headings F1A and FIN. [Also in Division H2] In a diaphragm pump for liquid or gas comprising a diaphragm 15 secured to a rod 13 and actuated on its pumping strokes by the armature 17 of an electromagnet 18, 19 and on its suction strokes by a diaphragm spring 12, the electromagnet is axially adjustable by means of a rotatable member 23 to vary the pump delivery. A scale is marked on the flange 26 of the member 23 to co-operate with an index mark on the pump housing 10. The suction strokes of the pump may be produced by a further electromagnet on the opposite side of the armature. It is stated that a pair of diaphragms may be mounted on opposite ends of the rod when a pair of electromagnets are provided, the diaphragms operating in separate pump chambers.
