Abstract
Controlling maximum fluid pressure at the outlet end of a peristaltic pump of the general type disclosed in U.S. Pat. No. 4,482,347 is achieved by supporting the resilient tubing of the pump in the trough of a rigid but movable platen mounted upon a compression pad or spring arrangement that resists platen movement until a back pressure of predetermined magnitude occurs, at which time the plate is displaced to reduce pumping efficiency and prevent further increases in outlet pressure.
