Abstract

1290504 Valves WALTER SCHEELE KG MASCHINENFABRIK 17 Oct 1969 [18 Oct 1968] 51176/69 Heading F2V [Also in Division F1] A distributing valve for a concrete pump comprises a two-part slide member 8a, 8b controlling flow between inlets 1, outlets 5, 6 and pump cylinders 2, 3. The slide member is part-conical, and has easily replaceable wear-resistant members (16) and sealing members (17), Fig. 5 (not shown). The outer valve housing part containing inlets 1 and outlets 5, 6 is hinged to the inner part 12. The slide member is moved by control pistons acting through a pivoted lever (19), Fig. 1 (not shown).
