Peristaltic motors

Abstract

A peristaltic motor is provided comprising a reciprocating slave piston adapted to be actuated by the progressive, sequential contraction of two aligned, resiliently deformable peristaltic tubes by a weighted roller such as a wheel of a heavy vehicle. The leading ends of both tubes, that is the ends first contacted by the moving roller, are connected to the slave cylinder, one on either side of the piston and the trailing ends of the tubes are connected to one another so that movement of the roller from the leading end to the trailing end of the first tube causes the hydraulic fluid therein to move down the tube and into the slave cylinder moving the piston through half a stroke. Movement of the roller in the same direction over the second tube, forces the hydraulic fluid into the other side of the slave cylinder to move the piston through the second half of the stroke. The piston is associated with means to utilize its movement such as an air compressor or a pump.
