Abstract

1,260,374. Concrete pump. F. SCHWING April 10, 1969 [April 11, 1968], No.18333/69. Heading F1A. A concrete pump comprises a pair of cylinders 1, 2 having out-of-phase pistons 3, 4 reciprocable therein, the cylinders 1, 2, being connected to a control housing having an outlet 8 and a pair of inlets 9, 10 and a pair of partially rotatable valve members 6, 7, which in their end positions connect the piston on a suction stroke (piston 4 as shown) to one inlet 10, and the piston on a delivery stroke to the outlet 8. At the end of the piston strokes the valve members switch over to the positions 6a, 7a to connect piston 4 to the outlet 8 and piston 3 to the inlet 9. [GB1260374A]
