Abstract

1,272,467. Reciprocating pumps. MODINE Ltd. Sept.14, 1970 [Sept.12, 1969], No.45103/69. Heading F1A. A pump for dispensing measured quantities of beer comprises coaxial cylinders 10, 11 with pistons 15, 16 connected by a rod 17, pumping chambers being defined between the inner faces of the pistons and a partition 12, and actuating chambers between the outer faces and end covers 14. The pumping chamber stroke volume, e.g. half a pint, is set by adjustable stops 19 which are locked by wiring and sealing to tie rods 13, Fig. 4 (not shown). Compressed air is admitted alternately to the actuating chambers by a valve 44a controlled by a two-position manual valve 52 which connects the air supply line 49 to either side of valve 44a for movement of pistons 15, 16 to the left or right, line 49 being connected to valve 44a at 45. On movement of the pistons, the pressure from the exhausting actuating chambers acts via valve 44a on a diaphragm 47 which opens a shutoff valve 55 to connect air supply line 49 to a differential piston valve 50a in the supply line to manual valve 52, thereby moving valve 50a to cut-off the supply to valve 52, preventing interference by the operator with the dispensing stroke, once initiated. At the end of the dispensing stroke, a bleed orifice in the diaphragm housing slowly vents the exhaust pressure to close valve 55 in a time slightly longer than that taken for the dispensing stroke, valve 50a then restoring the air supply to valve 52 ready for the next cycle. A slide valve 28, Fig.2 (not shown), controlled by valve 52 changes over the pumping chamber connections 20, 21 between beer supply line 25 and discharge line 38. A sensitive non-return valve 60 adjacent dispensing nozzle 39 prevents beer in the system from going flat. Each piston 15, 16 has a cruciform sealing ring 22 and a cup-leather 23.
