Abstract

1,272,789. Reciprocating pumps. H. M. ZIMMERMAN. Dec. 10, 1969, No.60313/69. Heading F1A. A concrete pump, e.g. for mounting on a vehicle Fig. 8 (not shown), comprises a pumping piston 68 reciprocated by a fluid motor 72, 74 and drawing concrete from chamber 26 into chamber 10 via an inlet gate valve 94 and discharging it into pipe 104 via outlet gate valve 102, fluid motors (100) and 110 controlling the valves being actuated synchronously by a control valve in a fluid circuit, Fig. 4 (not shown), and entry of air into chambers 26 and 10 during the pump suction stroke being prevented by flap valve 114. The circuit includes a control valve for actuating motor 72, 74. Concrete is supplied to chamber 26 from a chamber 42 by a feed screw 44 operated by a fluid motor 50 supplied independently of motor 72, 74. Chamber 42 is supplied with concrete by a hopper 56 rotatable about bearings 58, 60 by handle 62, and incorporating an agitator 64, 66 driven by screw motor 50 through chain drive 67. Piston 68 has O-ring seals 80 and a facing 86 of P.T.F.E. or rubber. Chamber 10 is hinged to cylinder 22 for cleaning, Fig. 3 (not shown). (For Figure see next page)
