Abstract
1423879 Reciprocating pumps MASCHINENFABRIK WALTER SCHEELE 5 Oct 1973 [5 Oct 1972] 46544/73 Heading F1A A concrete pump comprises two piston/cylinder units 1, 2 operating out of phase, and alternately drawing concrete from a common inlet 3 and discharging it to a common outlet 4 under the control of a valve comprising an oscillatable shaft 9 carrying a plate 8 controlling the alternate connection of passages 17, 18 to inlet 3, and a plate 10 controlling the alternate connection of passages 17, 18 to outlet 4. Plate 10 is pear-shaped and extends downwardly from the top of plate 8. Outlet housing 7 has a flanged portion 11 providing a bearing for shaft 9 and formed with sealing webs (12, 13), Fig. 4 (not shown), engageable by plate 10 on axial adjustment of shaft 9. An intermediate plate 15 has abutments 19 limiting the movement of plate 8. Housing 17 is detachably secured by screws 16 via plate 15 to housing 14 to facilitate access to the valve assembly.
