Abstract
A fluid motor is disclosed that has a housing with a body portion formed as a hollow circular cylinder. A series of peristaltic tubes are disposed in the housing with one end of each tube leading from an inlet manifold on the housing and with the other end of the tubes open to the hollow interior of the housing. The tubes are disposed about the inner perimeter of the cylindrical body. A pair of rollers engage with each tube. The rollers for each tube are mounted on the ends of arms that extend in diametrically opposite directions from a motor shaft journaled in the housing. The rollers for each tube are angularly displaced with respect to the rollers for the other tubes about the axis of the motor shaft. Fluid under pressure entering the inlet will cause the rollers to advance along the length of the tubes and thereby rotate the motor shaft.
Claims9
A fluid motor comprising:
- a hollow enclosure having a fluid inlet and a fluid outlet;
- an output shaft journaled in the enclosure;
- a flexible tube connected at one end to the inlet and opened at its other end to the hollow interior of the enclosure;
- and
- a roller collapsing the tube and movable along the length thereof, said roller being drivingly mounted to the shaft,
- whereby fluid under pressure at said inlet will cause the roller to advance along the length of the tube to thereby move the output shaft and the fluid will exit the tube into the hollow interior to act upon the outer surface of the tube.
A fluid motor comprising:
- a housing having a fluid inlet and a fluid outlet;
- an output shaft journaled in the housing;
- a plurality of flexible tubes in the housing each communicating at one end to the inlet and at their other end being open to the interior of the housing, said flexible tubes being supported throughout their length along one side of the tube;
- and
- a roller for each tube rotatably mounted on the end of an arm extending radially from the shaft, said roller extending into an opposite side of the flexible tube to compress the same.
