Abstract

1367048 Reciprocating pumps WAGGON UNION GmbH 29 March 1973 [30 March 1972] 15204/73 Heading F1A A pump, e.g. for operating hydraulicallyactuated, emptying valves on railway tank wagons, comprises a spring-loaded piston reciprocated by an eccentric 6, Fig. 1, rotated by hand wheels (5), Fig. 2 (not shown) the piston drawing liquid from a reservoir 10 via an inlet 9 and discharging the liquid via check valve 12 and conduit 14, Fig. 3, to open the wagon valves, a by-pass valve 15 being opened to cause the wagon valves to close. The hand wheels may be selectively connected to the eccentric by plug-in couplings (4), Fig. 2 (not shown). By-pass valve 15 is movable into its open position by a rod 16 connected by link 17 to a pivoted lever 18 biased by spring 19 to open the by-pass valve, and connected to a rope 21 which is tensioned to close the bypass valve. A pressure-relief valve 13 also is provided.
