Abstract
A pump and a method for pumping liquid or fluid through a pair resilient es includes a shuttle block which partially compresses the tubes in a balanced, alternating manner. The resilient tubes are held in a parallel relationship with a predetermined space defined therebetween. Within the predetermined space, a shuttle block is oscillated along the linear axis to partially compress the tubes in an alternating fashion. As one of the two parallel tubes is compressed, fluid is pumped out of the tube and at the same time fluid is drawn into the second tube as the latter tube resumes its original shape. The resilience of both tubes also is used to assist the pumping action in a balanced fashion, thereby providing a pump that has low power consumption and is lightweight.
