Abstract

1284202 Reciprocating motors SOC ANON STOP 23 April 1971 [5 May 1970] 10899/71 Heading H2A [Also in Divisions F1 and H1] An electromagnetically-actuated, diaphragm pump comprises a diaphragm 12 moved on its suction stroke by its resilience and on its discharge stroke by energizing a coil 40 to move soft iron core 54 and rod 56 downwardly, a switch 90, 94 controlling energization of coil 40 being operated towards the end of each stroke by abutments 60 and 62 on rod 56 engaging a sleeve 66 which slides to move an elastic blade 80 over-centre to open or close contacts 90, 94. Blade 80 is supported by notches 86, 92 in insulated portions of the pump housing, and has tongue portions 88, 95, Fig. 4, engaging elastic blades 78 mounted in apertures 76 of sleeve 66. Core 54 engages an elastic foam washer 52 at the end of the suction stroke. Lift valves are provided in the pump inlet and outlet, Fig. 3 (not shown).
