Abstract

1380812 Peristaltic pumps J W CHAFER Ltd 5 Sept 1973 [28 Sept 1972] 44753/72 Heading F 1 F [ Also in Division F2] A peristaltic pump comprises a length of tubing 1 having an oval cross-sectional shape with an oval inner face 3 and an oval outer face 4 interrupted at diametrically opposite points on the major axis with an axially extending reinforcing rib 6. The ribs 6 are provided at the "corners" of the tubing that are formed when the tubing is rolled flat in use and eliminate the formation of cracks in the tubing. The pump, Fig. 2, comprises a framework 7 with a spindle 8 carrying three rollers 9 spaced at 120 degrees to roll the tubing flat against a backing plate 11 which also extends over an arc of 120 degrees.
