Abstract

1375801 Reciprocating pumps A E COOPER 5 Jan 1973 [7 Jan 1972] 699/73 Heading F1A A pump for delivering lubricant to a number of points on a machine comprises a piston 9 moved downwardly by an air motor piston 8 and upwardly by a spring 15 to draw lubricant from a reservoir 4 into a chamber 2 via a check valve 6 and to deliver the lubricant via piston passages 10, 12, an annular groove 11 and axially spaced delivery passages 13 to delivery pipes 14 having check valves 32. Air is intermittently supplied to piston 8 by a rotary valve comprising a fixed disc 18 with an inlet port 27 and an outlet port, and a rotary disc 19 with an arcuate port for intermittently connecting the inlet and outlet ports during rotation. For the return stroke, air is exhausted from above piston 8 by leakage between cover 31 and body 1 when the air supply is terminated by valve 18, 19. Disc 19 is rotated by a motor, or the machine to be lubricated, via a reduction gear-box 22, the gearing of which may be adjusted to adjust the lubricating interval. A spring 25 adjustable by wing nut 26 biases disc 19 against disc 18.
