Abstract

877,598. Flexible chamber pumps. STAVOSTROJ NOVE MESTO, NARODNI PODNIK. Dec. 15, 1959 [Dec. 17, 1958], No. 42606/59. Class 102(1). Flexible sleeves 1, 6 connected in series are subjected to liquid pressure in surrounding chambers 2, 7 connected respectively to the larger and smaller volume chambers of a differential piston and cylinder device 15 driven by a motor 20. The ratio of piston areas is 2 : 1 so that the pump discharges on each stroke of the device 15. An air chamber 24 may be included in the hydraulic circuit. The supply reservoir 21 is removable and the inlet may then be connected to a hose. The pump is used for conveying mortar.
